Yes, completely free. No sign-up, no payment, and no ads. Just open the page in your browser and it's ready to use.

Does the timer keep running if I switch tabs?

Yes. It uses a Web Worker to count the time, so the countdown stays accurate while you are looking at another tab.

Can I set a length other than 5 minutes?

Yes. Set any duration with the presets, the stepper, or the keypad. Pin the ones you use most and you can start them again in a single tap.

Does it work on my phone?

Yes. It runs in the browser on iPhone, iPad and Android with nothing to install. Add it to your home screen to use it full-screen like an app.

FAQ

What is the Pomodoro Technique?
Focus for 25 minutes, then rest for 5. After four cycles, take a longer 15-minute break. Pomo Clock lets you customise focus, short break and long break durations down to the minute.
Is it really completely free?
Yes — every feature is free right now, and there are no ads. We run it as part of Mihata's content marketing.
Will Pomo Clock ever become paid?
If we expand into bigger features (cloud sync, calendar integration, richer notifications), a paid plan may eventually appear. Our intent, though, is to keep the free tier genuinely usable, and to make any paid plan something you'd actually want to keep using.
Do I need an account?
No login required. Open the page in any browser and you're ready. Settings are saved only to your browser's local storage; nothing is sent to a server.
Where are my settings saved? Is my data private?
Only in your browser's local storage and IndexedDB (for uploaded images). Nothing ever reaches Mihata's servers, and there's no account, so no third party can see your data.
Which devices does it work on? Does it support iPhone, iPad, Mac, PC, and Android?
Yes — Pomo Clock runs on any device with a modern browser, including iPhone, iPad, Mac, Windows PC, Android, and Chromebook. No installation required; just open the page and start using it.
Does it work without an always-on display? Will the screen stay on?
Yes. Pomo Clock has a built-in screen wake lock — the display stays on as long as the page is open, even if your device's auto-lock is set to a short interval. Just leave it charging and it doubles as a beautiful standby clock, no always-on display needed. Add it to your home screen (PWA) for the best experience.
Does the Pomodoro keep running when the tab is in the background?
Yes — a Web Worker keeps the timer accurate even with the tab hidden. When a session finishes, you get a browser notification (permission required) and an audio chime.
Can I reuse an old iPad or smartphone as a desk clock?
Yes. Open Pomo Clock in your browser, disable the screen auto-lock, and add it to your home screen (PWA). You can repurpose an unused old iPad, iPhone, or Android as an aesthetic desk clock, sleep clock, or standby screen on a charging dock.
Can I use my own YouTube videos or playlists as BGM?
Yes. Open the Music & Ambient panel, switch to YouTube, and paste any video or playlist URL. Playback runs through YouTube's official IFrame Player API, so it stays compliant with YouTube's Terms of Service.
Will Pomo Clock be released on the App Store or Google Play?
Right now we ship as a browser app + PWA (add to home screen). We're considering native iOS / Android distribution and Google Calendar integration in the future. The plan is to grow the free web version first, listen to feedback, and bring those features in over time.
Who builds and maintains this app?
Pomo Clock is built and operated by Mihata, a small team focused on web development, custom AI development and AI integration support. The clock is the kind of focus app we wanted for ourselves — equal parts design / UX craft and AI-augmented engineering. Read the in-panel column for the full story.
Where can I send feature requests or bug reports?
Use the 'Contact' link inside this panel — it goes straight to Mihata's contact form. Even rough "would be nice if…" ideas are welcome. We can't promise to ship every request, but we read each one carefully when planning updates.
