## What is Sincery?

Sincery is the days since counter you have always wanted. Add an activity. Check in when you do it. Sincery shows how many days have passed since the last time. That is all.

Some things come around regularly — watering the plants, changing the sheets, calling a parent, taking the car in for service. Not often enough to keep precisely in your head, but often enough to matter. Sincery keeps track of the gap so you do not have to.

HOW IT WORKS

Add an activity and give it a name. Hold the number button to check in. Sincery shows the date of the last check-in and the number of calendar days elapsed. Set an optional expiry period and the check-in button changes color when you are overdue. Sort your activities by name or by days.

NO NOISE

No subscription. No ads. No account. No cloud sync. No notifications. No streaks. No scores. No data collection. Your activities stay on your device and nowhere else.

PRICING

Sincery is free for up to three concurrent activities. A one-time purchase unlocks unlimited activities — no ongoing fees.
