About

Pact31

Read full description

Pact31 is the accountability app that turns consistency into a team sport. Show up, prove it, and let your pact keep you honest—at any fitness level. Pact = Your squad, 31 = days/month max. Create or join a pact: a group committed to moving every day. Your daily target is the day of the month—do 1 rep on the 1st, 15 on the 15th, 31 on the 31st. Finish your set, submit proof, and earn your points. Your pact sees it, reacts, and keeps you going. Miss a day? A makeup submission still counts for half credit—because showing up late beats not showing up at all. No shortcuts, no excuses—just steady progress together. FEATURES • Daily proof check-ins — video for gym moves, photo for distance activities (miles, cycling, steps, swimming). Proof builds trust and momentum • Day-based targets — the date sets your reps or distance (1–31) for a simple, scalable challenge • Points that reward consistency — on-time check-in earns 10 pts, makeup earns 5. Every rep counts • Pact chat — real-time group messages with emoji reactions • Absence votes — miss 3 days in a row and your pact gets a 24-hour vote on whether to remove you. Majority rules. Stay consistent or get cut. • Pact vs. Pact Battles — challenge rival groups to a month-long battle. Scores are averaged per member so any size pact can compete fairly. Winners get a shareable Certificate of Victory and a permanent win on the leaderboard • Battle Feed — watch rival proof roll in live, track the real-time scoreboard, and fire off trash talk in the battle chat • Challenge wins history — your all-time win record never gets deleted. Build your legacy • Money Pot — set stakes for a challenge; losers see exactly what they owe and settle up directly with the winners via Venmo, PayPal, or cash, outside the app • Leaderboards — see who's leading inside your pact and globally across all public pacts • Workout calendar — track your streak and makeup days at a glance • Custom ranks — climb from Couch Potato to Unstoppable as your lifetime completions grow • Reminders — set your daily nudge to stay on track • Personal stats — streak, best streak, total days done, rank progress • Notifications — get notifications when another pact member submits their check-in and/or option to set a daily reminder for yourself • Supports push-ups, sit-ups, squats, pull-ups, burpees, lunges, dips, plank, jumping jacks, mountain climbers, miles run, cycling, daily steps, swimming, yoga, and more Whether you're just getting started or pushing PRs, solo or with friends, Pact31 keeps you consistent—and makes it fun. Make your pact. Keep it.
