Start timers for anything: learning Danish, Company A, meditation. Run several at once, pause and resume, and see where the time went. Works offline, no account needed.

What it does

Several timers can run at the same time, and each can be paused and resumed.
Tags that nest: org:ob, ob:support. Filter by one and its children are included.
Reports for a day, week, month or any range, with the time zone and the day start shown every time.
A day starts when you say it does: work until 3am still counts as yesterday.
Works fully offline from your device. Sign in with Google only if you want your devices in sync.
Free, no ads. Anonymous usage counts and crash reports only if you say yes.
