One rule. Every day. Don't break the chain.
Most habit apps drown you in features, charts, and reminders you ignore. Lock In does the opposite. It's built around a single, unbreakable rule: pick your "one do," show up every day, and don't break the chain. Miss a day and your streak resets to zero. That's the whole point — the cost of skipping is what makes you actually show up.
HOW IT WORKS
1. Take a 60-second quiz. Tell us your goal, what's been holding you back, and what kind of person you're trying to become. We build a personalized plan around your answers — not generic advice.
2. Sign your pact. Press and hold to commit. "One do. Every day. No skips."
3. Pick your one do. Start tiny — read 10 pages, drink water, walk 5k steps, no phone in bed. The smaller the do, the harder it is to skip.
4. Lock in daily. Open the app, check the box, watch the streak climb. Miss a day? It's gone. Start over.
WHAT'S INSIDE
– A streak engine that actually means something. No "streak freezes," no second chances, no participation trophies. The rule is the rule.
– A custom-designed daily home screen built around your streak — clean, focused, no clutter.
– Your Dos: track multiple habits without losing the focus on your primary lock-in.
– Streak stats and XP. Watch the chain grow. See how far you've come.
– Daily reminders. One ping at the time you choose. Adjustable, optional, and never spammy.
– Cross-device sync. Sign in with Apple, Google, or email — your streak follows you everywhere.
– Sign in with Apple is fully supported with privacy-respecting authentication.
– Premium experience with no ads, no tracking pixels, no dark patterns.
WHO IT'S FOR
– People who've tried every habit tracker and given up.
– Builders, lifters, readers, writers, founders, students — anyone with one thing they want to do every single day.
– Anyone tired of streaks that don't matter and "gentle nudges" that change nothing.
WHY LOCK IN IS DIFFERENT
Most apps soften the rules to keep you happy. Lock In keeps the rules sharp to keep you honest. The streak isn't a number — it's a contract with yourself. The only way to win is to show up. The only way to lose is to skip. That's it.
SUBSCRIPTION
Lock In offers a yearly and monthly subscription. Cancel anytime in your Apple ID settings. Subscriptions auto-renew unless turned off at least 24 hours before the end of the current period. Payment is charged to your Apple ID account at confirmation of purchase.
