Features

Simple tools for
lasting change.

Daily check-ins

Mark habits done or skipped — one tap, no confirmation dialogs. Skips happen; they don't break your streak.

Honest streaks

Missing a day breaks your streak. That's the point. A streak is only valuable if it's real.

Activity heatmap

A 4-month GitHub-style calendar showing your history at a glance. Pattern recognition, simplified.

Daily reminders

Optional per-habit notifications at a time you choose. Never nagging — only when you want them.

Offline-first PWA

All data lives in IndexedDB on your device. Works without a network. Add to home screen for a native feel.

Zero accounts

No sign-up, no server, no data ever leaving your device. Uninstall the app and your data is gone. Period.

Philosophy

No backend.
No database.
No analytics.

Habits are personal. Your data should be too. Flint stores everything in IndexedDB on your device — there is no server to leak it. There is no analytics to track you. There is, simply, just an app.

Tech stack

Lean tech, sharp edges.

The 2026 rebuild is going fully native — Swift & SwiftUI, on-device storage, the works. Below is the stack the original web prototype was forged on.
