Timestamp – the log for things you do once in a while. Can't remember when you last changed your toothbrush? Ran a backup? Defrosted the fridge? Opened that tube of tomato paste? Now you can. Create an activity for anything you do occasionally. Every time you do it, tap once to log a timestamp. The app shows you when you last did it – and how many days it's been. Not a habit tracker with streaks and daily goals. A record of the things you only do every few weeks, months, or years – and always forget. WHAT PEOPLE TRACK - Chores – cleaning, laundry, watering plants, changing the sheets - Home & maintenance – filters, backups, car service, oil change - Kitchen – when you opened that jar, sauce, or bottle - Health & routine – medication, haircuts, dentist, workouts - Pets – vet visits, flea treatment, grooming - Anything else you keep forgetting HOW IT WORKS - Create an activity in seconds – no setup, no account - One tap to log: Add timestamp - Instantly see the last time and the days since - Add an optional note to any timestamp - Browse the full history of every activity, grouped by month - Edit or delete any entry

When did you last do that? Sincely answers exactly that one question. Rotate the mattress, deworm the cat, test the smoke detector, call your mother-in-law – one tap logs the moment, and the app shows you plainly: "12 days ago." This is not a to-do app. No streaks, no points, no guilt. The number is the hero – not a red due date screaming at you. Green is the normal state. Red is rare and stays calm. HOW IT WORKS • Add an entry, pick an emoji, done. • One tap on "Done just now" when you did the thing. • An optional interval tells you when it's time again – without nagging. WHAT'S INSIDE • Home & Lock Screen widgets – your status at a glance. • Gentle reminders when an interval comes due (your call). • Full history per entry: average, past times, all editable. • Siri & Shortcuts: "Hey Siri, log watered the plants." • iCloud sync across all your devices. • 100% offline. No account, no tracking, no ads. SINCELY PRO (one-time, no subscription) • Unlimited entries (free: up to 5). • All widget styles for Home & Lock Screen. • Add due dates straight to your calendar. • Icon packs & alternate app icons. Pay once, keep it forever. Notifications stay free too. Promise. Sincely is for the things no calendar holds and no to-do list deserves – but that still want doing. Eventually.

Verdict
The clearest difference is in-app purchases: Timestamp at none against Sincely's 1. Sincely's advantage is update cadence (every 5 days vs every 6 weeks). On price, ads, device support and iOS requirement there is nothing between them.
