Bonsai Timer | A board of countdown timers, plus pomodoro and stopwatches

01Features

What it does

It works without an account and keeps everything on the device; signing in syncs the timer board, preset library, pomodoro settings and saved stopwatch results between devices, while live stopwatches and the running pomodoro stay on the device they started on.

01Board

Timers that run side by side

Each timer is a glass bubble with a coloured ring that drains as the time runs down. Tap a bubble to start or pause it, and long press it to change its settings. Timers count towards a fixed end time, so they stay accurate when the app is closed and opened again.

Add as many timers as you like with the + button
Set a name, a duration in hours, minutes and seconds, a colour and an alarm tone for each timer
A finished timer turns red and keeps sounding until you tap it
A timer that ran out while the app was closed comes back stopped at zero instead of ringing
Save any timer to the library from its settings

02Library

Presets you can start in one tap

The library keeps the durations you use often. Tap a card and a running copy goes onto the board, or long press it to edit or delete it.

Four starter presets on a fresh install
Each preset keeps its own colour and alarm tone
Durations read plainly, like 6 m 30 s or 2 h 30 m
Create presets with the + button or save them from a live timer

03Sounds

A different tone for every timer

Every timer and preset has its own alarm sound, so you can tell which one finished without looking. Tapping a tone in the picker plays a preview. Seventeen of the eighteen tones were synthesised for the app.

Tones include Singing Bowl, Temple Bell, Marimba, Kalimba, Gong, Koto, Cuckoo and Retro
Previews play on their own channel, so they never cut off a timer that is ringing
The pomodoro has one tone for the end of focus and another for the end of a break

04Pomodoro

A pomodoro cycle with long breaks

Focus, short break and long break run in order, with a long break after a set number of focus rounds. Only finished focus intervals count towards the long break, so skipping one does not bring the break forward.

Focus up to 180 minutes, short breaks up to 60 and long breaks up to 120
Choose 2 to 8 rounds per set
Breaks start on their own by default and focus waits for a tap, and both can be changed
Restart the current interval, skip to the next one or reset the whole cycle
Round dots and a count of finished focus intervals show where you are

05Stopwatch

Several stopwatches, each with laps

Keep more than one stopwatch, each with its own name, and switch between them from the chips at the top. The lap list shows each split and the running total, with the fastest lap in green and the slowest in red.

Lap, save, reset and delete buttons sit under the dial
Tap the name to rename a stopwatch
The ring sweeps once a minute, like a second hand
A running stopwatch is still running when you reopen the app

06Results

Saved results with every lap

Save a stopwatch reading to keep its total and all its laps. Results are listed newest first with the date and lap count, and a row opens to show every lap.
