Zero friction to start. Open a browser, go to pure-flon.com/tools/pomodoro/, press Start. No app store, no download, no account creation. You can be running your first Pomodoro in under 10 seconds.
Works everywhere equally. Same experience on your work laptop, home computer, phone, and tablet. Forest's desktop support is limited to a Chrome extension; our tool works in any modern browser on any platform.
Completely free, forever. No "freemium" tier, no ads, no subscription to unlock features. The tool is entirely supported by voluntary GitHub Sponsors, Ko-fi, and PayPal.
Zero data collection. Your focus sessions are tracked locally in your browser. Nothing is sent to a server. If privacy is important to you (it should be), browser-based tools with local storage are the more private choice.
You need phone-locking to prevent distraction. Forest's signature feature — locking your phone screen during a session — is a powerful intervention for people who habitually check their phone. A browser timer can't do this. If your main enemy is your phone, Forest's lock feature is genuinely useful.
Gamification keeps you motivated. Growing a virtual forest, collecting tree species, and contributing to real-world tree planting resonates deeply with some users — especially students. If visual rewards and environmental impact keep you engaged, Forest's gamification may be worth the cost.
You want detailed historical statistics. Forest tracks months of focus data with daily/weekly charts, streak calendars, and productivity patterns. If long-term tracking matters to you, Forest's data features are more comprehensive than our timer's session counters.
For most users who want a fast, free, no-friction Pomodoro timer that works on any device, the pure-flon timer is the better default choice. For users who specifically need phone-locking or want long-term gamified motivation, Forest is worth the small cost.
Forest is $1.99 on iOS. On Android it's free with ads; a paid version removes ads. The Chrome extension is free with limited features. Premium subscriptions unlock advanced statistics and more tree species. pure-flon Pomodoro Timer has no paid tier — it's free in all browsers with no ads.
Yes. pure-flon Pomodoro Timer runs at pure-flon.com/tools/pomodoro/ in any modern browser. No install, no account. On mobile, you can add it to your home screen for app-like access (Safari on iOS: Share → Add to Home Screen; Chrome on Android: Menu → Add to Home Screen).
Yes. Forest partners with Trees for the Future (trees.org). Users earn virtual coins by completing focus sessions, and those coins can be spent to have Forest make a real-world donation for tree planting. It's a genuine component of the app, independently verified by the nonprofit partner.
For a free, browser-based alternative without gamification, pure-flon Pomodoro Timer is a strong choice. For web-based alternatives with task tracking, Pomofocus.io is worth trying. For macOS/iOS users who want a free native app, Be Focused has a generous free tier.
