Flowkeeper vs Forest

Flowkeeper is a desktop Pomodoro timer and work-tracking tool built around the original Pomodoro Technique. It is available for Linux, macOS, and Windows; the Free plan costs nothing and has no subscriptions or paid features. Work organization includes task lists, daily backlogs, todo lists, reminders, and configurable categories. Fullscreen rest notifications are enabled by default, and users can set a notification to sound one minute before a Pomodoro ends. Keyboard shortcuts, timer and tray icon appearance, themes, and audio are configurable. Work summaries can be exported as Markdown, CSV, or JSON, and data can be exchanged as text. Data is stored locally in plaintext files that users can copy, back up, and edit. Flowkeeper works offline; users can share the data file manually or enable Watch changes, while online sync is under development. It can run external programs on application events. The maker says version 0.7.x only makes network calls to check for updates through the GitHub API, and those checks can be disabled in Settings. The FAQ identifies Constantine Kulak as author and says Flowkeeper is GPL-licensed.

Forest is a focus timer that makes a virtual tree grow during a session and die if the user leaves or breaks the session. Deep Focus can block or redirect attempts to open other apps, including on the free tier. Time Guard schedules recurring app or site blocks; Free covers one app or site, while Plus supports multiple. Plant Together synchronizes a session among friends, and the group’s trees die if anyone gives up. Mindful Space offers guided breathing and soundscapes, and Focus Analytics reports focus patterns and hours by day, week, or month. Plus adds analytics and custom tags. Forest says focus-earned coins can fund real trees through its partnership with Trees for the Future, up to five per account on eligible plans. The timer, tree growth, and local focus data work offline, but group focus, challenges, the shop, seasonal events, and real-tree planting require internet. Forest works on iPhone, iPad, Android, and as a Chrome or Firefox extension; account and focus history can sync across platforms. Forest describes it as a behavioral tool, not an ADHD medical treatment.
