The app allows you to define time budgets, which are not much more than a few mutually exclusive countdown timers. The UX is essentially that of a chess clock for an arbitrary number of players with configurable time.
The whole point of the app is to kick you out of the running role/priority when its time is up. One feature that was essential for me was AlarmKit alarms, which only became possible last year (>= iOS 26.1). Another was watchOS support, as a natural surface for time-related matters.
The current version is strictly focussed. The timers track time allocation during one day. All timers are reset at midnight. I didn't build any statistics - you can export the raw internal SQLite store and make any evaluation or dashboard you want from there.
I don't plan to extend the app nor to convert it into a service. All data stays local on your devices (synced between phone and watch locally) and fully open to you. No need for an account or subscription. Thus, I ask for a small one-time fee of $1.99.
