Best tool to track my activities

I’ve been using the app for over two years now to track my activities and it works perfectly for me. Even though I have a smart watch it doesn’t provide such reporting as this app. Fun, simple, functional.

Can’t even use basic functionality without paying

Asking for premium that costs ₹500 just to do the most basic task that is click to mark a date. This is literally the simplest an app can get. Uninstalled this and created my own in 10 mins with Claude.

Super

Pour ceux qui aime tout ecrire et bien organiser les archives cette app est kool et tu paye juste une fois ensuite tu la a vie.

Great!

Simple, easy to use, and does exactly what it’s supposed to do.

I love the app.

I strictly use it to keep track of my day to day movement. It’s an accountability check.

If you look at your month and you’re not happy, then the next month you make sure you visually can see that change. The app does this.
