MyChronoWorks

Timers that decide what happens over time

Instead of asking how long, MyChronoWorks asks what should happen over time. Every timer, stopwatch, interval trainer or alarm is a job: a timeline of phases with cues attached to moments in it. Start from a template or build your own, and run as many as you like at once.

What is in the app

  • Jobs made of phases

    A job is a timeline of phases such as work, rest and preparation, with repeat blocks. Timers, stopwatches, interval trainers and alarms are all jobs.

  • Cues at any moment

    A cue can beep, speak, vibrate, flash the torch, ring a bell or show a notification, at the start, every so often, before the end or at random. It can act differently with headphones, low battery or a silent ringer.

  • Templates to start with

    Sport, Health, Cooking, Work and Chimes templates such as HIIT, Pomodoro, Tea, Stopwatch, a Speaking timer, a Talking clock and Ship's bells. The app remembers the values you used last.

  • Many jobs at once

    Tea, eggs and laundry can count down together, each with its own card and notification. Jobs can start other jobs, and a group starts several with one tap.

  • Start by sound

    Give a job a sound trigger, a clap or a whistle, or clap during a run to take a lap or skip a phase. The microphone listens only while the app is on screen.

  • History and event log

    Every finished or cancelled run is recorded with each phase change and cue. See laps and insights, share them as CSV, and choose how long history is kept.

  • Game clocks and tools

    Clocks for chess, Go, shogi, backgammon and Scrabble, a tally counter with timestamps, event countdowns and a pace calculator.

  • World clock and planner

    Add cities or your own places, see every clock from another city's point of view, drag a time slider and find the best shared hours for a call.

  • Widgets, tile and shortcuts

    Home-screen widgets for a job, your clocks, a binary clock and a countdown, a Quick Settings tile, and launcher shortcuts for a new job.

Questions and answers

Does MyChronoWorks need an internet connection?

No. Everything works offline, and the app has no network permission at all.

Why does the app ask for the microphone?

Only for sound triggers: a clap, a whistle or a loud noise that starts a job, or a clap during a run. If you never use them, you are never asked. It listens only while the app is on screen, and no audio is stored or sent.

Will my timers fire on time when the phone sleeps?

Yes. The app sets exact alarms and keeps a running job alive with a foreground service, so cues fire on time while the phone sleeps. If your phone holds background apps back, the ChronoLab screen shows it: it checks exact alarms, notifications and battery optimization, and runs a 60-second self-test that shows how many milliseconds late a cue fired.

Can I move my jobs to a new phone?

Yes. Export jobs writes all your jobs and groups to one file, and Import jobs reads it back after showing what it contains. You can also share a single job with a friend.

Does the world clock use my location?

No. The city list is built into the app, and places you add yourself are entered by name and coordinates.

What is a cue that did not sound?

The finish ring uses the alarm volume, ticks and speech use the media volume, and a conditional cue may have taken its other branch. The run's event log in History shows which one fired.

What does it cost?

Nothing. MyChronoWorks is free. There is nothing to buy in the app, no subscription and no advertisements.
