What it does – The Pomodoro Timer by DangNH Studio turns the classic 25‑minute work / 5‑minute break technique into a simple, offline web app. It tracks each session, stores results in localStorage, and lets you adjust lengths for custom workflows.
Key features
- Standard 25/5 cycle with optional long breaks
- Custom session lengths (e.g., 50‑10, 15‑5)
- Real‑time countdown with audible alerts
- Local statistics saved in the browser (no server needed)
- Responsive design for mobile and desktop
Basic usage steps 1. Open the app at /apps/pomodoro?lang=en on any device. 2. Press Start to begin a 25‑minute focus timer (or set a custom duration in Settings). 3. When the timer ends, a short alert signals a 5‑minute break; click Start Break. 4. After the break, click Resume to begin the next Pomodoro. Stats update automatically.
Short example – You need to write a report. Open the timer, hit Start, work for 25 minutes, then click Start Break for a 5‑minute walk. After three cycles, the app suggests a longer 15‑minute break. All sessions appear in the local stats panel.

FAQ
Can I change the default 25‑minute work period?
Yes. Open Settings, adjust the Work Duration field, and save. The new length applies to all future sessions.
Where are my Pomodoro statistics stored?
Statistics are saved locally in the browser’s localStorage, so they persist across sessions on the same device.
Does the timer work offline?
Absolutely. After the initial page load, the app runs completely offline and does not require any server calls.
Can I use the timer on a smartphone?
The interface is fully responsive and optimized for mobile browsers, so you can start, pause, and view stats on any phone.
