Receira for Papra
Receira is a fast, private, native app for your self hosted Papra document server. Capture, organize, search, sign, and read your entire archive, from receipts and bills to contracts and IDs, right from your iPhone, iPad, and Apple Watch. Everything stays on a server you control. Receira is completely free. There is no subscription, no in app purchase, and no account to buy. You connect the app to a Papra server you run or have access to, and your documents are instantly at your fingertips. Think of it like a mail app, but for your personal paperwork. SET UP IN UNDER A MINUTE A simple, guided setup walks you through connecting to your server and signing in. Point Receira at your Papra address, choose how you sign in, and you are ready to go. SCAN AND CAPTURE Scan paper with your camera and Receira reads the merchant, date, and total on device, then names and files it for you. An adaptive review screen recognizes whether you are capturing a receipt, a card, or a document and shows the right fields. Import from Files or Photos, upload several at once, or scan a multi page stack and split it into separate documents. FIND ANYTHING Full text search looks inside your documents, not just their titles. Organize with color coded tags and one tap suggestions, and let the Smart Inbox surface anything still untagged. READ THE TEXT ON ANY SCAN With Live Text, tap a phone number, address, link, or date on a scanned page to call, open, or save it in a moment, or simply select and copy the text you need. SIGN AND MARK UP Sign and annotate documents right on your device. Open a PDF, add your signature, notes, or highlights, and Receira saves the result as a new copy so your original always stays untouched. Your signature stays exactly where you place it and syncs across your devices. NEVER MISS A DEADLINE Set a reminder on any document, whether it is a bill due, a warranty window, or a renewal, and Receira notifies you before it matters. Reminders sync across your devices. YOUR SERVER AT A GLANCE A clear Server and Storage view shows your connection status, latency, last sync, and how much you are storing, all in one place. ON YOUR WRIST A companion Apple Watch app puts your recent documents, search, and offline favorites right on your wrist. SIGN IN YOUR WAY Connect with email and password, add two factor authentication, or use single sign on (SSO or OAuth) if your server runs Authentik, Keycloak, Google, and more. SHARE WITH FAMILY AND TEAMMATES Create organizations and invite people by email as Members or Admins, manage roles, and switch between organizations anytime. When you share a file into Receira, you can choose exactly which organization it goes to. PRIVATE BY DESIGN Your documents live on your server, never ours.

Splash: Chlorine Pool Care
Pay once for Pro. No subscription, no ads, no account. Works offline. Splash is the iOS chemistry assistant for chlorinated freshwater pool owners. Enter your test readings — free chlorine, pH, total alkalinity, calcium hardness, cyanuric acid, water temperature — and get exact doses scaled to your pool volume. Source-aware: pick your chlorine source (trichlor tablets, cal hypo, dichlor, liquid bleach) and Splash factors how each one moves CYA and CH alongside the chlorine. Why source-aware matters: every pound of trichlor tabs adds about 6 ppm of cyanuric acid to a 10,000-gallon pool. Most pool apps recommend "shock with trichlor" without forecasting where your CYA will be in eight weeks. Splash projects CYA forward based on your dose history and warns you before the pool chlorine-locks. Features • Test & Adjust: 6-parameter readings → recommendations with brand-cited dose math • Source-aware dosing for trichlor, cal hypo, dichlor, and liquid bleach • CYA trajectory: forecasts where your stabilizer will be in 4 / 8 / 12 weeks • FC/CYA active-chlorine visualizer — what percent of your FC is actually sanitizing • CSI (Calcium Saturation Index) — scale vs etch risk indicator • SLAM mode — TFP-validated algae recovery walkthrough with FC target by CYA • Brand-cited dose math for HTH, Clorox Pool & Spa, BioGuard, Pool Essentials, Leslie's, In The Swim, and generics • Pool volume estimator for rectangular, round, oval, and kidney shapes • Named-source citations: Trouble Free Pool methodology, manufacturer documentation • Universal app for iPhone and iPad For pool owners who don't want to memorize forum threads. Chlorinated freshwater pools 1,000–100,000 gallons. Free download with the basic liquid-bleach calculator unlocked. $6.99 one-time unlocks Splash Pro permanently — source-aware dosing for trichlor / cal hypo / dichlor, CYA trajectory, FC/CYA visualizer, CSI, and SLAM mode. No subscription, no ads, no account, no cloud. Privacy: Splash collects nothing. No analytics, no accounts, no network requests. Your settings live on your device. Have a saltwater pool? Look up Saline by the same developer for cell-aware saltwater chemistry.
Aquascape: Planted Tank Calc
Free to download. Try every Pro feature free for 48 hours, then unlock for life with a one-time purchase. No subscription, no ads, no account. Works offline. Aquascape is the iOS planted-aquarium fertilizer dosing calculator. Pick a methodology — Estimative Index, PPS-Pro, or PMDD — choose a tank type, enter your tank's volume, and Aquascape computes a per-salt weekly schedule plus a Today card that shows what to dose right now. The Moon Dog wedge for Aquascape is brand-aware liquid dosing on top of methodology. Pick Seachem Flourish, NilocG Thrive, or 2HR APT and the Liquid Dose screen scales each SKU's manufacturer-label rate to your tank's volume — with shrimp-safe gating that removes Flourish Excel from shrimp tanks because glutaraldehyde stresses inverts. Every dose recommendation cites its source URL inline. Features • EI (Standard, Daily, Low Light / Weekly), PPS-Pro, and PMDD — methodology recipes from Tom Barr, ChrisCowAU/Edward, and Sears & Conlin • Per-salt weekly schedule: KNO₃, KH₂PO₄, K₂SO₄, MgSO₄, CSM+B with Mon/Wed/Fri macros and Tue/Thu/Sat traces • Liquid Dose by Brand: Seachem Flourish (7 SKUs), NilocG Thrive (4 SKUs), 2HR APT (APT 1, APT 3, APT e) — scaled to tank volume, methodology-filtered, source URL cited • CO₂ estimator: pH + KH → ppm with six colored safety zones (too-low, low-normal, target 25–35 ppm, high-normal, warning >40 ppm, danger >60 ppm) and plain-English advice for each band • GH/KH remineralization: Seachem Equilibrium, Salty Shrimp GH+, Salty Shrimp GH/KH+ — grams to dose, plus shrimp species ranges (Neocaridina, Caridina, Sulawesi) for shrimp tanks • Multi-tank: track a nano, a display tank, and a shrimp tank in parallel — each with its own methodology, volume, units, and dosing history • Dose history: one-tap log per day, swipe-to-delete, grouped by day • High-tech or shrimp tank type — shrimp tanks gate Excel-class products and surface species GH/KH ranges • Liter or US-gallon units, switchable per tank • Universal app for iPhone and iPad For planted-tank hobbyists running EI, PPS-Pro, or PMDD with dry salts or brand-aware liquid bottles. The audience is r/PlantedTank, Barr Report, and the broader UKAPS / 2HR Aquarist / RotalaButterfly readership — anyone who's been pasting numbers into a web calculator and wants an iOS-native tool that runs on a plane. Free to download and dose one tank with the full methodology dry-salt engine. Aquascape Pro — a one-time $6.99 unlock, free to try for 48 hours — adds Liquid Dose by Brand, the CO₂ estimator, GH/KH tools, unlimited tanks, and dose history. No subscription, no ads, no account, no cloud sync. Privacy: Aquascape collects nothing. No analytics, no accounts, no network requests. Your tanks, methodologies, brand selections, and dose history live on your device via SwiftData. Brand dose tables and methodology recipes are bundled at install time and never touch the network either. Methodology sources cited in-app: Tom Barr (Estimative Index, Barr Report Forum), ChrisCowAU and Edward (PPS-Pro original recipe), Sears & Conlin 1996 (Poor Man's Dosing Drops). Brand sources cited in-app: Seachem's per-SKU dosing labels, NilocG's published dosing-information page, 2HR Aquarist's APT methodology FAQ. Chemistry sources: Chuck Gadd's pH/KH/CO₂ table, Seachem's Equilibrium label, Salty Shrimp's GH+ / GH/KH+ labels. Planted-aquarium nutrient targets are hobbyist-canonical. No peer-reviewed publications were used; targets follow the methodology authors and brand label rates. The CO₂ estimator assumes carbonate buffering is the only contributor to pH — if you dose phosphate buffers, run Indian almond leaves or peat, or have soft acidic source water, the estimate will overstate actual CO₂.
Flush: Mushroom Cultivation
Pay once for Pro. No subscription, no ads, no account. Works offline. Flush is the iOS calculator and grow tracker for gourmet and medicinal mushroom cultivation. Enter substrate weight, pick a species, and get hydration math, sterilization protocols, biological efficiency forecasts, and per-flush yield predictions. Named-source citations on every default — Stamets's Growing Gourmet & Medicinal Mushrooms, Cotter's Organic Mushroom Farming and Mycoremediation, Cornell Small Farms' Northeast Mushroom Project, Field & Forest plug-spawn standards, and peer-reviewed studies in Journal of Fungi and PLOS One. Hard scope: gourmet and medicinal edible species only. Oyster, lion's mane, shiitake, king oyster, reishi, maitake, pioppino, enoki, chestnut, turkey tail, and cordyceps militaris. Flush does not support, reference, or instruct on psilocybin or any controlled substance. Why named-source citations matter: practitioner trust depends on tracing every default — sterilization PSI/time, biological efficiency range, fruiting CO₂ ppm, spawn-to-bulk ratio — to a source you can verify yourself. Flush surfaces "Per Stamets:", "Per Cornell BMP:", "Per Field & Forest:" on every numeric default, with a Sources tab linking to the original references. Features • Hydration calculator: HWP, CVG, straw, Masters Mix, supp. sawdust, Wu '93 shiitake — exact water-to-add math, squeeze-test guidance • Grain spawn: rye, millet, wheat, sorghum, popcorn — per-grain hydration %, soak time, sterilization PSI / time, jar fill • Agar recipes: MEA, PDA, DFA (Cotter's Dog Food Agar shortcut) — scale to any volume • Liquid culture: 4% LME, honey, corn syrup — with downstream inoculation rates • Sterilization matrix: PSI / time / method per substrate • Biological efficiency forecast: per-species BE range × dry weight → lifetime yield with first-flush and per-flush decrement curves • Plug spawn for logs: Cornell BMP geometry + Field & Forest 50-plug standard + Hericium 80-plug exception • Eleven species library: oyster, lion's mane, shiitake, king oyster, reishi (kidney-cap vs antler CO₂ targets), maitake, pioppino, enoki, chestnut, turkey tail, cordyceps militaris — each with colonization and fruiting temp/RH/CO₂/BE/casing rules and citation lineage • Brand presets: Field & Forest, North Spore, Mushroom Mountain, Out-Grow • Multi-grow tracker: log substrate batches, readings (temp, RH, CO₂), events (inoculation, shake-break, fruiting init, FAE adjust, contamination), per-flush harvests with auto-computed BE • Sources tab: named-source attribution with direct links • Universal app for iPhone and iPad For home and small-farm growers using PF Tek, monotub, shotgun fruiting chamber, Martha tents, agar work, grain-to-grain transfers, liquid culture, and outdoor logs. Free download with the hydration calculator, BE formula, three species (oyster, lion's mane, shiitake), and one active grow. $6.99 one-time unlocks Flush Pro permanently: Masters Mix and supp. sawdust calculators, agar, liquid culture, grain spawn protocol, the expanded eight-species library, reishi's inverted CO₂ kidney-cap vs antler target, plug spawn for logs, multi-flush yield tracker, unlimited grows, and brand-aware preset detail. 48-hour trial starts when you first tap a Pro feature. Privacy: Flush collects nothing. No analytics, no accounts, no network requests. Your grows live on your device. Like calculators with citations? Look up Press (hard cider), Crust (pizza dough), Trace (cold-process soap), Splash (chlorine pools), and Hide (leatherworking) by the same developer.
Hide: Leathermaker's Calc
Hide is a leatherworking calculator with cited math. Every SPI, every thread-length rule, every edge-finish recommendation names its source. Pay once at $6.99 for Hide Pro — no subscription, no ads, no scanner. The wedge Most leatherworking apps stop at thread length.

Garage: Car Care & Service Log
The complete owner's log for everything your car needs you to remember — fuel, service, repairs, and what's due next — kept offline on your phone, and exportable as the service record a buyer actually wants at resale. No subscription. No account. No cloud required. FUEL & ECONOMY Log every fill-up and Garage tracks your real fuel economy between full tanks — MPG, or L/100km, in whatever units your car uses. Spot a sudden drop before it becomes a repair bill. SERVICE & REPAIR HISTORY Record every oil change, brake job, tire rotation, fluid flush, and mod — date, mileage, shop, cost, and notes. A clean, complete timeline you'll be glad you kept. MAINTENANCE REMINDERS THAT THINK AHEAD Track each maintenance item by mileage, by time, or both — whichever comes due first. Garage ships with the common items already set up (oil, tires, brakes, filters, coolant, spark plugs, timing belt, brake fluid) using typical normal-vs-severe intervals you can edit to match your own owner's manual. A "Due Soon" view shows what needs attention across all your vehicles at a glance. RESALE-READY EXPORT Export any vehicle's full history as a clean PDF to hand a private buyer, or as CSV for your own records. A documented service history is one of the simplest ways to protect a car's value — these are records that pay you back at sale. ADD A CAR IN SECONDS Type a VIN and Garage fills in make, model, and year from the free NHTSA database — or enter the details by hand. Add a photo and current odometer and you're logging. HONEST BY DESIGN The maintenance intervals in Garage are typical, editable defaults — not a reproduction of your manufacturer's exact factory schedule. Always confirm against your owner's manual. Garage is a record-keeping tool; it doesn't give mechanical or safety advice. BUILT RIGHT • Works fully offline — your garage, your data, no tracking. • Miles or kilometers; US, Imperial, or metric fuel units. • Multiple vehicles for the whole household or your project cars. • Dark theme, full Dynamic Type, and VoiceOver support. • Universal — iPhone and iPad. FREE TO TRY, PAY ONCE Log your first vehicle and everything that goes with it for free. A one-time unlock adds multiple vehicles, PDF/CSV resale export, and custom reminders — yours forever, no subscription. Try every feature free for 48 hours.
Wick: Candle Maker's Calc
Wick is the candle-maker's calculator — every number you need to pour a candle, cited and in one place, instead of a stack of web pages. Enter your vessel and wax, and Wick gives you: • WAX NEEDED — by vessel volume and container count (volume × the wax's specific gravity). • FRAGRANCE LOAD — the oil weight for your target %, with a safety guardrail: it warns when you exceed your wax's max or your fragrance's IFRA limit (oil bleed and wick-choke are real fire risks). • WICK SIZE — a starting-point ECO/CD recommendation by container diameter, bumped up for a heavy load or dark dye. • ADD / POUR TEMPS and CURE TIME for your wax. • COST & PRICING — your true cost per candle and your margin, for makers who sell. WHY WICK Every number traces to a named source — CandleScience and The Flaming Candle wick guides, IFRA Category 12 limits, and wax-manufacturer spec sheets. No guesswork, no "trust our formula." • Save unlimited recipes and reuse them • Ounces or grams • 100% private and offline — no account, no cloud, no ads • Pay once. No subscription, ever. Wick's numbers are a cited starting point. Candle making involves open flame and hot wax — always burn-test your own candle for safety.
Well: Off-Grid Water Calc
Well is an off-grid water-system sizing calculator and log for homesteaders, rural property owners, and households on private wells, cisterns, or rainwater catchment. Every threshold, every dose, every sizing recommendation cites a named source — Penn State Extension, USDA NRCS, ARCSA, Texas A&M AgriLife, EPA, USGS, NSF/ANSI 55. The Safe Drinking Water Act doesn't regulate private wells. 23 million US households are on their own. Well makes the official guidance readable, calculable, and tied to your specific system. WHAT WELL DOES • Rainwater harvest — Roof area × annual rainfall × material runoff coefficient. Metal 0.95, tile 0.90, asphalt 0.80, green 0.30 per Texas A&M AgriLife. Optional first-flush per ARCSA 63-2020. • Tank and cistern volume — Vertical cylinder, horizontal cylinder, rectangular. Plus the 10–15% freeboard rule for real working volume. • Cistern sizing for demand — Household × per-person daily use × buffer days (3, 7, 14, 30) → required gallons. Recommended Norwesco HDPE preset. • Pump sizing — Bathrooms → peak GPM. TDH = pumping level + above-ground rise + delivery pressure × 2.31 + 5% friction. HP recommendation against Goulds GS (Xylem) or Franklin Electric FS / FPS / 3200 curve range. Per USDA NRCS 210-NEH Parts 631 + 650 Ch 12. • Pressure tank drawdown — Amtrol Well-X-Trol WX-201 / -202 / -203 / -255 / -302 drawdown at 30/50, 40/60, 50/70 PSI. Motor-protection pump-cycle target. • Well drawdown + recovery — Pumping test math. Static vs pumping water level, specific capacity, sustainable yield, recovery time. Per USDA NRCS CPS 642. • UV dose — NSF/ANSI 55 Class A (40 mJ/cm² anti-pathogenic) vs Class B (16 mJ/cm² supplemental). Viqua VH150 / VH200 / VH410 sizing. Pre-filter check (hardness > 7 grains/gal or iron > 0.3 mg/L). 9,000-hour lamp schedule. • Filtration stages — Ordered recommender from your water-test inputs: sediment → iron/manganese → softener → arsenic → carbon → UV. Softener sized in grains by household × hardness × 5-day regen cycle. Arsenic flagged at 0.005 mg/L (recommended) and 0.010 mg/L (EPA MCL). • ARCSA checklist — 16-item compliance checklist per ARCSA/ASPE/ANSI 63-2020 covering catchment, conveyance, tank entry, treatment, distribution, backflow prevention. MULTI-ENTITY HISTORY Save unlimited water systems with components (well, pump, pressure tank, storage, UV, filter, softener, RO), water-test results with EPA MCL badges (green / yellow / red), and recurring maintenance reminders (UV lamp 365 d, pre-filter quarterly, pressure-tank precharge annually). SwiftUI Charts trend per analyte. PERMANENTLY FREE Safety-critical reference stays free, always: • EPA MCL reference — arsenic, nitrate, lead, coliform, uranium • Rainwater laws by US state — 50 + DC with statute citations (CO HB 16-1005, UT §73-3-1.5, CA SB 1422, TX Tax Code §151.355) • Testing cadence — per Penn State Master Well Owner Network • Citations & Sources with URLs • Water-test result MCL badges — existing logged results stay visible 48-HOUR TRIAL, THEN $9.99 ONE-TIME Every calculator, every brand preset, every paid feature unlocks for the first 48 hours after install. After the trial, $9.99 unlocks Well Pro for life. No subscription. No ads. No analytics. No data collection. Family Sharing not enabled. NOT WHAT WELL IS • Not a medical or water-quality testing device. MCL badges read against your reported lab results — they don't measure water. • Not a state-licensed driller log. • Not an AI advisor. Every recommendation is rule-based against a named-source range. Made by Moon Dog. Pay once, no subscriptions.
Groove: Turntable Setup Calc
Set up your turntable the right way — cartridge alignment, tonearm resonance, and loading — with every number traced to its source. No subscription, no account, works offline. CARTRIDGE ALIGNMENT Enter your tonearm's effective length (or pivot-to-spindle distance) and Groove gives you the exact overhang, offset angle, and null points. Choose your geometry: Baerwald (Löfgren A), Löfgren B, or Stevenson, against IEC or DIN groove radii. The math is the classic Löfgren/Baerwald two-null solution — verified against the published reference values, not guessed. RESONANCE MATCH The single most-asked vinyl question: is my cartridge a good match for my arm? Enter the arm's effective mass and the cartridge's compliance and mass, and Groove shows the tonearm/cartridge resonance frequency — with a clear read on whether it lands in the 8–11 Hz sweet spot, below it (warp and footfall trouble), or above it (into the audible band). Cartridge spec'd at 100 Hz? One toggle converts it. CARTRIDGE LOADING Dial in the electrical load. For moving-magnet cartridges, Groove adds your cable and phono-stage capacitance and compares it to the cartridge's target. For moving-coil, it gives the recommended load impedance. SAVED PER TURNTABLE Keep your deck's numbers in a saved profile so you're not re-entering them every time you swap a cartridge or check resonance. SOURCE-CITED, ALWAYS Every figure names its authority — Löfgren and Baerwald for alignment, Hi-Fi News for the resonance window, the IEC/DIN groove standards, Vinyl Engine and Korf Audio for the reference tables. A Sources screen links them all. Groove tells you where each number comes from so you can verify it yourself. BUILT RIGHT • Works fully offline — no account, no tracking, no data collected. • Dark theme, full Dynamic Type, and VoiceOver support. • Universal — iPhone and iPad. FREE, WITH AN OPTIONAL ONE-TIME UNLOCK Groove is free to use: Baerwald alignment (IEC and DIN), the full resonance calculator, the setup reference, and one saved turntable. Groove Pro is a single one-time purchase — no subscription — that adds: • Löfgren B and Stevenson alignments • Cartridge loading (MM capacitance budget and MC impedance) • Unlimited saved turntables GOOD TO KNOW Groove is a setup aid, not a substitute for your tonearm and cartridge manuals. Compliance and mass figures come from your cartridge's published specs; confirm against the manufacturer. A printable on-screen protractor is on the way in a future update — for now Groove gives you the precise numbers to set on your own protractor.

Turf: Lawn Care Calculator
Turf is the lawn-care calculator that doesn't sell you fertilizer. Most "lawn apps" are a funnel for one brand's products — Turf is a neutral, citation-backed tool that just does the math: how much nitrogen, how much seed, how much lime, what spreader setting, what dilution. Every number cites a named university turf-extension source. No account, no ads, no subscription, works offline. NITROGEN RATE (FREE, FOREVER) Enter your bag's N-P-K analysis, your target nitrogen rate, and your lawn size. Turf returns pounds of product per 1,000 sq ft and for the whole lawn, bags needed, and a slow-release advisory — with a hard guardrail if you exceed the roughly 1.0 lb N per 1,000 sq ft single-application cap (Purdue, Virginia Cooperative Extension). The hero calculator is free forever, at full citation quality. TURF PRO (ONE-TIME $4.99, NO SUBSCRIPTION) A single $4.99 purchase unlocks the other five calculators — pay once, keep forever, restore across your devices: - Spreader calibration — the weigh-back method to dial any spreader to your target rate, because the settings printed on the bag are starting points, not guarantees (Penn State). - Liquid dilution / tank-mix — convert a product's label rate into ounces per gallon and per 1,000 sq ft, driven by your real, measured sprayer output (US EPA, extension calibration method). - Lime & sulfur pH amendment — pounds per 1,000 sq ft to raise pH with lime or lower it with elemental sulfur, by soil texture (sand / loam / clay), with per-application caps (Michigan State, Penn State, Clemson HGIC, University of Minnesota, NC State). - Grass seed rate — pounds of seed per 1,000 sq ft, new seeding vs. overseed, by species: KBG, tall fescue, perennial ryegrass, fine fescue, bermuda, zoysia, centipede (Penn State, Cornell, Texas A&M). - PGR growing-degree-day timing — accumulate GDD to time your next Primo Maxx / T-Nex (trinexapac-ethyl) application, on the Kreuser & Soldat model. HONEST BY DESIGN Turf shows its work and flags what's disputed. The popular "sand 25 / loam 75 / clay 100" lime table isn't in any primary extension publication, so Turf uses the documented turf topdress band instead — and tells you so. The 200-GDD PGR target is validated for golf putting greens, not home lawns, so Turf says that plainly rather than pretending it's universal. For any pesticide or plant-growth regulator, the law is the product label. SOURCES Purdue Turfgrass, Virginia Cooperative Extension, Clemson HGIC, Penn State Extension, Michigan State University, University of Minnesota, NC State, Cornell, Texas A&M AgriLife, US EPA, and Kreuser & Soldat (PGR growing-degree-day model). DISCLAIMER Turf is an educational reference calculator, not professional agronomic or pesticide-application advice. Always follow the product label and confirm rates with your local cooperative extension office. For any pesticide or plant-growth regulator, the label is the law: it is a violation of federal law to use a product in a manner inconsistent with its labeling (US EPA). Free download includes the full nitrogen-rate calculator. Turf Pro is a single one-time purchase ($4.99) that unlocks spreader calibration, liquid dilution, lime & sulfur, seed rate, and PGR timing. No subscription, no ads, no account.
