About this app

Turn 31 days into lasting habits — with accountability that actually works.

31Done is a social habit-tracking app built around one simple idea: you're more likely to stick with something when someone's counting with you.

How it works:

Create or join 31-day challenges around anything — fitness, reading, meditation, learning a language, or whatever habit you want to lock in. Track your daily progress, share updates on the social feed, and let your friends hold you accountable.

Key features:

🏋️ 31-Day Challenges — Set a goal, track your progress day by day, and watch your streak grow. Public, friends-only, or private — you control who sees what.

👥 Social Accountability — Connect with friends, send and accept friend requests, and see each other's progress in real time. Nothing motivates like knowing someone's watching.

💬 Social Feed — Share updates, post photos, and react to your friends' challenges. Celebrate wins and encourage each other through the tough days.

👨‍👩‍👧 Groups — Create groups and invite friends to share challenges together. Keep your closest circle accountable as a team.

📊 Stats & Streaks — Track your total challenges, active challenges, completion
percentage, and longest streaks. See your growth over time.

🔔 Push Notifications — Get reminded to log your daily progress so you never break the chain.

🔒 Private & Secure — Your data is yours. Set challenges to private, friends-only, or public. Create an account with secure email verification and persistent login.

Why 31Done?

Research shows it takes anywhere from 18 to 254 days to form a new habit. 31 days is the sweet spot — long enough to wire in real behavior change, short enough to actually commit to it. And when you add social accountability to the mix, success rates skyrocket.

Whether you're trying to get in shape, read more, meditate daily, or break a bad habit, 31Done gives you the structure and the community to make it stick.
