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.
