Wrenwhistle: Stoppuhr, Timer und Wecker

Stopwatch, countdown timers and alarms in one small toolbar popup: laps you can export, as many named timers as you need, and alarms that tell you when they were missed.

Type the time like on an oven: 2, 5, 0 gives 2:50. Or click a preset (1, 3, 5, 10, 25, 45 minutes, or your own) and the timer runs. Give each timer a name and a colour, so you always know which one is ringing: «Steeping tea», «Laundry», «Standup call».

• Stopwatch with hundredths, laps (key L), fastest and slowest lap marked, copy or CSV export for a spreadsheet
• Up to 20 named countdown timers at once, from 1 second to 99:59:59, with pause, +1 min and Repeat
• Countdown on the toolbar button: 12m, then seconds in the last minute
• Rings with the popup closed: a notification with the timer name and one of 8 alarm sounds, or your own MP3, OGG or WAV
• Alarms for a time of day, by weekday or once, with snooze; a new alarm is on right away
• If the browser was closed at alarm time, you see «Missed at 07:30» instead of a late ring
• Big view in its own tab for classrooms, meetings and projectors: huge digits, a tick ruler of the time left, the time in the tab title, full screen with F
• Keyboard control: Space, L, R, N, F, plus browser shortcuts to open the popup, start the stopwatch and stop a ring
• History of the last 30 stopwatch sessions
• Backup to a JSON file and import in a new browser
• Light and dark theme, 16 languages, right-to-left layout for Arabic

Compact by design: the popup is 360 × 520 pixels and never covers the page you are reading.

Private: only the permissions a timer needs (alarms, notifications, storage; in Opera also offscreen, to play the sound). No access to the websites you visit, no account, no analytics, no network requests. Your timers, alarms and sessions stay in this browser. Works offline in Firefox and Opera.
