DailyStreak is a habit tracker built around an opinion: tracking a habit should cost seconds, never minutes, and missing a day should be information, not punishment.

It’s also the proving ground for Tracker OS — the first complete product built on the shared platform.

Product choices

One-tap everything. The core loop — open app, see today, tap done — is engineered to be the fastest path in the product. Undo, skip, notes, and backfilling exist, but never in the way of the main tap.

Humane streaks. Streaks motivate until they shame. DailyStreak’s streak rules treat planned skips and rest days as part of a sustainable pattern rather than failures, and the weekly review speaks in terms of trends (“up 12 points from last week”) instead of broken chains.

Insight that respects the user. The stats engine computes completion rates, weekday patterns (your strongest and toughest days), per-habit streaks, and a weekly review with tone-aware recommendations — all from local data.

Genuinely useful free plan. Up to five habits with reminders, streaks, calendar, and notes — enough to live with daily. Pro adds depth: unlimited habits, advanced statistics, weekly review, themes, export, and cloud sync.

Built to be reliable

  • Works fully offline and anonymously — no account required to use the whole app.
  • Syncs across your devices once you sign in, with changes that hold up even on a flaky connection.
  • Native home-screen widgets on Android and iOS, always up to date.
  • Available in many languages, including right-to-left layouts.
  • Privacy-preserving by design — your habit names and notes never leave your control for analytics.
  • Extensively tested, with every change verified automatically before it ships.
