iPhone
The only habit tracker that works like a game. Create challenges for reading, studying, or waking up early. Hold friends accountable and celebrate streaks together.
Build better habits with friends. Nudge is the social accountability app that helps you actually stick to your goals—with real stakes.
Tired of breaking promises to yourself? Nudge turns your goals into group challenges where friends hold each other accountable. Set the rules, track daily progress, and face real consequences when you slip up. No more excuses.
HOW IT WORKS
Create a Challenge – Start a challenge for any goal—waking up early, reading daily, learning a language, or staying sober. Set the duration and invite friends with a simple code.
Define the Rules – Add rules like "Read for 30 minutes daily" or "Journal for 5 minutes." Require photo proof for extra accountability. You set the stakes.
Log Daily – When you open the app, you will see your daily check-in. Tap to confirm you completed your tasks or upload photo proof. Takes seconds.
Face Real Consequences – Miss a day? You will owe the group. Set money fines (paid via Venmo) or custom social forfeits like "Buy everyone coffee" or "Post an embarrassing photo." Your friends decide.
Celebrate Together – See your group's progress in the daily feed. Send reactions. Build streaks. Watch everyone level up together.

WHY NUDGE WORKS
Most habit apps rely on willpower alone. Nudge adds what is missing: social pressure and real consequences.
When your friends can see whether you logged, you show up. When skipping means paying $5 or completing a social forfeit, you think twice. When everyone is building streaks together, you do not want to be the one who breaks the chain.
