Certain: OCD ADHD Reassurance

Ever left home and wondered "Did I lock the front door?" or "Did I switch off the gas hob?" Certain is designed to give you peace of mind by helping you confirm and record important safety tasks before you leave home.
Whether you experience OCD, ADHD, anxiety, or simply want better reassurance about everyday safety routines, Certain provides a simple solution to stop the endless loop of doubt.
How It Works:
Create items you want to track; doors, windows, lights, gas hobs, appliances, or anything that matters to you. Organise them by room for easy reference.
When you lock or switch off each item, record that action in the app. Each confirmation includes a timestamp, and you can attach an optional photo for visual proof.
Later, when doubt creeps in, review your confirmations anytime. See exactly when you completed each task, complete with the photo evidence you captured.
Key Features:
• Simple, intuitive interface designed to reduce anxiety
• Photo evidence with each confirmation
• Date and time stamps for every action
• Organise items by room
• Two item types: Lock/Unlock and On/Off
Privacy First:
All your data stays on your device. No cloud storage, no tracking, no accounts required. Your confirmations are yours alone.
Free & Premium:
Free: Track up to 5 items
Certain Plus: Unlimited items and photos for £0.99/month or £6.99/year
Certain is a record-keeping tool that helps you document what you've done, providing reassurance when you need it most.
