“I always had the will on Sunday night, but as soon as Monday morning came, it was ‘maybe next week.’ So I built Commity. Now missing a commitment has an instant consequence. Losing a couple of bucks gives you a ‘let's just do this’ feeling rather than the one where you just stay in bed.”
“I'm pretty consistent, but there are days when I just need a push, and Commity does it for me. Some days, the thought of losing 50 bucks for skipping the thing I wanted just the night before is enough to send me there… :)”
“I really like the app and It's features. I needed an app for motivation and when I had similar apps I could just lie about going to the library to study. However, Commity needs your phone to be in the desired location in order to complete the task! I like that feature very much. Also, at first I was using free trial, but now motivation is even higher when there is real money at stake.😁”

Pick your spot, set your goal, choose your rules, put money on it, and sign the pact.
The campus library, a reading room or your study café - drop a pin and set a fence around it. From now on, standing inside that circle is the only thing that saves your money.
15 minutes or 2 hours — pick the daily time that would satisfy you and choose only the days you can honestly make. The plan should fit your real life, not an ideal week.
Strict means every scheduled day truly counts. And if you do miss one, it's not the end — a 5-day comeback wins 66% of your stake right back.
$5 or $50 — pick an amount that gets you out of the house. Nothing is charged today, you lose money only moves if you bail on your goals.
Read every line, it's a promise to you, not to us. Put your signature, seal it and start showing up. In the app, this is the moment it becomes real.
A "mark as done" button is easy to fool at 11pm. Commity's check-in is different: when you arrive you tap I'm here, and a live GPS check has to confirm you're actually at the library before a single minute counts.
This is what a study tracker looks like when it can't be fooled. No self-reported hours, no focus timer you can pause from bed.
You walk into the campus library and tap "I'm here." GPS confirms you're inside the fence, and your study check-in begins.
Read, write, revise — the minutes count in the background. A coffee run outside the fence pauses the clock until you're back.
Ninety verified minutes. Your study streak grows, your stake stays yours, and tomorrow starts from momentum instead of guilt.
Pin your gym or library on the map. When you arrive, one tap checks you in and GPS has to confirm you're really there before a single minute counts.
The moment you hit your daily goal, the session ends on its own. If you leave early, you must return inside the radius in order to continue. There's no check-out button to forget.
No tracking, no pressure, and never a charge on days you didn't schedule.
Put real money behind your word. You're only charged when you miss, handled securely by Stripe.
Tap in, pocket your phone, and go. The timer keeps running and reminders fire even after a restart.
Commitments renew weekly and you can cancel at the end of any week.
Start your comeback.
Five clean days and 66% of your money comes back. Pick the days that fit — then just show up.
of your $25 stake
Up to 5 days — fewer days means more weeks.
Head to your spot on each comeback day, tap "I'm here" to check in, and hit your daily goal. It counts in the background once you've tapped in.
Every day you complete lights up one of your 5. Watch the comeback streak fill on your dashboard.
Miss a single comeback day and the streak ends — no win-back. That's the deal that makes it work.
Complete all 5 and $16.50 lands back on your card automatically. Done.
Most habit apps punish a slip and walk away. Commity gives you a way back. If your stake ever does get charged, you have 30 days to start a comeback.
Put together a streak of 5 days which you can schedule in the next 5 weeks and 66% of your money comes back. Show up from the start and you're never charged at all — the door is never locked.
Start a commitmentChecking in takes one tap when you arrive. After that you can put your phone away — your timer keeps counting in the background, and Commity nudges you near your spot so you never forget the tap.
A quick GPS check confirms you're really there, and your timer starts on the spot.
Close the app, lock your phone — every minute inside your spot keeps counting in the background.
Commity reminds you when you're near your spot, and again in the evening — so a missed tap never means a missed day.
Showing up isn't only about the money. Each completed day earns Grit — points that rank you up through six friendly tiers, build your streaks, and unlock badges. A little proof, on your profile, of exactly how far you've come.






No professor takes attendance on your ambitions. Commity is the commitment device app that does.
Finals in six weeks? Five library days a week with a small stake beats a beautiful color-coded plan you'll abandon by Wednesday.
Nobody checks whether chapter four got written today. The fence does. Show up, check in, and let the pages pile up.
Bar exam, language cert, career switch — studying alone means nobody notices when you don't. A stake notices. (Squats instead of citations? The same pact runs our gym accountability app.)

Motivation is unreliable. A good commitment device turns showing up into the default. Commity uses real stakes + GPS check-in at your library so you build study streaks even when you don't feel like it.
Consistency isn't willpower — it's a system that makes showing up the easy choice. The trick is to give skipping a real, immediate cost. Commity does this by letting you put a small stake on your study days: show up at the library and you pay nothing, miss a scheduled session and your stake is charged. Suddenly "I'll study tomorrow" has a price, and staying consistent stops depending on how you feel that morning.
Motivation fades. Real commitment devices don't. Commity is a habit tracker and accountability app that lets you put a stake on your gym, fitness or study goals. With GPS check-in you prove you showed up. The plan runs automatically — perfect for building discipline even on low-motivation days.
Skipping has a real cost when money is on the line. Commity lets you stake on your study goals. Pin your library, use GPS check-in when you arrive, and keep your stake by showing up. Miss a scheduled day and you pay — most people need just that small push to build a real study streak.
Because the reward for a habit is far away, while the reward for skipping is instant — so your brain takes the easy win. Commitment devices fix this by moving a consequence into the present, and that's the science Commity is built on. By putting a small stake on each scheduled day, your long-term goal finally gets a short-term reason to win, and the habit has a chance to stick.
Yes — pin any place you actually go: the public library, a campus reading room, your favorite study café or a co-working space. If it has an address, the fence works.
Shorter than you think. Pick a goal you can hit on your worst day — 30 to 45 minutes is plenty to start — and let the streak do the compounding. You can always stay longer.
It can't write the essay for you, but it can make the couch cost money. A small stake plus GPS check-in at your study spot ends the nightly negotiation: show up or pay.
Spaced, repeated sessions are how material actually sticks — consistency beats cramming every time. Here's how to build a study habit that survives real weeks.
Forty-five real minutes at the library beats a fantasy four-hour block. Set a goal you can hit on your worst day — you can always stay longer.
Pick the days that fit your classes or shifts. Scheduled days build the study streak; everything else is a bonus.
Miss a session and the 5-day comeback starts: five show-ups, 66% of your stake back. One bad day never erases the habit — that's why staking money works.
Pin your library or study spot, put a small stake on your sessions, and use GPS check-in to prove you showed up. Commity makes study accountability simple — free to start, only charged if you miss.
Every payment runs through Stripe, the secure platform behind millions of businesses worldwide. Your full card details are stored by Stripe and never by us, everything is encrypted, and you're only ever charged automatically for a scheduled day you missed. Show up and it's always $0.
When you create a commitment you pin a place and a radius — your "geofence." When you arrive you open Commity and tap I'm here, and a live GPS check has to confirm you're actually inside that area before a single minute counts — so there's nothing to fake from the couch. From then on it's automatic: Commity logs your minutes and ends the day on its own the moment you hit your goal.
Yes — Commity is free to use, and you can start a 14-day trial with no card at all. After that you add a card so a small stake can back your goal, but you're charged exactly $0 for as long as you keep showing up on your scheduled days.
Yes. All payments are handled by Stripe — the same secure payments platform trusted by millions of businesses worldwide. Your full card details are stored by Stripe, never by Commity, and everything is encrypted end to end.
Only when you miss a day you scheduled. Show up on every scheduled day and the charge is automatically $0. There are no surprise fees, no subscriptions to your stake, and nothing ever happens on your rest days.
Yes. The moment you reach your minutes for the day, your day is marked complete and tracking stops automatically. You don't need to check out or remember to close anything — it just knows you're done.
Rest days are fully respected. On days you didn't schedule, nothing is tracked and nothing counts against you — no check-ins, no pressure, no charge. Rest is part of the plan, not a penalty.
Your stake is charged, but you get a comeback. Start a 5-day streak within 30 days and win 66% of your money back. Commity is built as a commitment tracker — it punishes misses lightly and rewards the return with streaks and discipline.
StickK and Beeminder proved that money on the line works — but both still rely on self-reporting or manual data entry. Commity closes that gap: a live GPS check-in confirms you're actually at your gym, library or studio, so there's no honor system to cheat. And a slip isn't just punished — you can win 66% of your stake back with a 5-day comeback. Read the full breakdowns: Commity vs Beeminder and the best StickK alternative.
Commity is built to be light on battery, and it only ever watches the one spot you pinned — never everywhere you go. On the days you've scheduled it does check your location in the background, so it can tell when you arrive and keep your timer running even with the app closed. To save power it stays on low accuracy while you're away from your spot and only switches on precise GPS once you're nearby — then it idles automatically the moment you hit your goal, and stays off entirely on your rest days.
Only for the tap. You open Commity and tap I'm here when you arrive — after that you can close it and your timer keeps counting in the background until you hit your goal. Reminders are scheduled on your phone too, so they fire even if the app is closed or your phone restarts.
Both. Commity runs natively on iOS and Android with the same check-in, streaks, reminders and comeback system on each.
Yes. You can adjust your goal, change your scheduled days, or cancel whenever you like. You're only ever charged for a scheduled day you missed before cancelling — never for stopping.
