Cycle Count Simply

Most period apps show you a confident date even when they're guessing. Cycle shows its confidence honestly: "about 9 times in 10, it lands in this window" — and tells you what would sharpen it.

EVERYTHING STAYS ON YOUR PHONE
No account. No server. No analytics. Your logs live in one file on your device; export them as JSON or CSV any time, or delete them truly — there is no cloud copy to linger.

AN ENGINE THAT LEARNS YOU
• Interactive cycle ring — drag to any day and it explains itself
• Predictions from your own last six cycles, recent ones weighted more
• Under 3 logged cycles it says "estimate" instead of pretending
• Irregular cycles get a wide honest window, not a fake date

LOGGING THAT TAKES 15 SECONDS
• Flow in real millilitres, not marketing words
• 0–10 pain with plain-language anchors
• Symptoms plus your own custom trackables — backdate up to a week
• No streaks, no guilt, ever

PATTERNS, NOT PLATITUDES
• "Your headaches cluster in the 3 days before your period — 8 of 10 cycles"
• Changes from YOUR baseline get flagged as "worth asking a doctor about"
• One-tap doctor report: cycle history, pain trends, questions to ask — as a PDF made for a 12-minute appointment

ASK ANYTHING
An on-device Q&A that reads your own logs, answers "is this normal for ME", escalates urgent symptoms to "see a doctor today", and never diagnoses. No question is too embarrassing, and nothing you ask leaves the phone.

Cycle describes; your doctor diagnoses. General information, not medical advice.
