A simple offline app for tracking when you last did something (Android + iOS)
I made a small app called “LastTap” for tracking irregular things that don’t really belong in a todo list or habit tracker.
Stuff like:
- changing water filters
- watering plants
- oil changes
- replacing contact lenses
- deep cleaning
- pet care
- taking “as needed” medication
- etc.
The idea is intentionally simple:
you tap once when you do something, and later the app tells you how long it’s been and roughly when you’ll probably need to do it again.
No streaks.
No productivity pressure.
No accounts.
No cloud.
Everything is stored locally on-device.
After a few logs, the app can estimate the next likely date based on your history.
Other details:
- fully offline
- no ads
- free version supports up to 3 tracked events
- optional one-time Pro purchase (no subscription)
- Pro also enables backup/export
- backups can be shared between Android and iOS devices
Android:
https://play.google.com/store/apps/details?id=com.lasttap
iOS:

Would love feedback, especially from people who tried similar “last time / since when” apps and found them too complicated or subscription-heavy.
