Flowkeeper vs Tomato Timer

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.

Tomato Timer is a focus timer for the browser and macOS, with a task list alongside timed work sessions. Its pattern alternates focused work with short breaks, then takes a longer break after four rounds. The browser timer includes a todo list for connecting sessions to tasks and lets users set custom focus durations; it runs without a download or signup. Browser data stays locally on the device. The native Mac app places its countdown in the menu bar and includes a todo list. It works offline, storing todos and timer history locally; the app's privacy policy says task, timer, and settings data are encrypted and not sent to external servers or third parties. The Mac app requires macOS 12.2 or later and supports Apple Silicon and Intel Macs. The web timer is free. The macOS app costs $3.99, paid once, with no subscription. Listed platforms are Linux, macOS, web, and Windows.
