No. FlowStack works entirely offline with no account, no signup, and no cloud storage. All your session data, tags, and settings are stored locally on your device using IndexedDB.
Can I install FlowStack on my phone's home screen?
Yes. FlowStack is a Progressive Web App (PWA) that installs to your home screen on Android, iOS, and desktop. Once installed, it works offline and launches in its own window — just like a native app, without any app store.
Does FlowStack have both Pomodoro and stopwatch modes?
Yes. FlowStack includes both a configurable Pomodoro timer (with work/break interval switching) and a free-form stopwatch mode for deep work sessions where you want to focus until you're done.
📲 Add to Home Screen — one tap to focus. Works offline, no account needed.
