Vow helps you build sustainable habits through daily check-ins, streak tracking, and partner accountability — all stored privately on your device. Zero backend. Zero excuses.
Simple enough to use every day. Powerful enough to drive real change.
Quick tap-based interface. Mark commitments as Done, Missed, or Skip. Undo anytime with a 5-second grace period.
Current, longest, and personal best streaks per commitment. Earn Streak Savers every 7 days, and use Vacation Mode to pause without penalties.
Invite friends via unique VOW-XXXXXX codes. Share challenges, a live leaderboard, and medal badges to keep each other honest.
Success rate charts, streak longevity rankings, best time-of-day heatmaps, and a year-in-review summary — all on-device.
Standalone watchOS app with today's commitments, haptic feedback, and 5 complication families to keep your streak front and center.
No backend servers. All data stored locally by default. Optional CloudKit sync is end-to-end encrypted — Apple can't read it either.
No account needed. Always free.
Everything in Free, plus:
Name your goal, set a frequency (daily to monthly), add a reminder, and optionally set an end date or difficulty level.
One tap — Done, Missed, or Skip. Your streak updates instantly. Miss one? Use a Streak Saver or trigger Vacation Mode to stay protected.
Watch streaks climb, explore analytics, share progress cards, and keep partners honest with challenges and leaderboards.
Vow is built with the latest Apple frameworks for a performance and privacy level no cross-platform app can match.
