Stick to your study plan orlose money.

An app that notices when you don't study. Most are timers you can pause or logs you fill in yourself. Commity checks with GPS that you're actually at your study spot and puts a small stake on each scheduled session, so skipping costs money and showing up costs nothing.

Make the plan specific, make it checkable, and give skipping an immediate cost. In Commity that means a place (your library or café), a daily minute goal, the days you'll go, how many weeks you're in for, and a stake you'd hate to lose.

Pick a term that ends after your last exam. If finals are seven weeks away, choose 8 weeks: the week you sign up counts as week 1 and the commitment ends on its own on the final Sunday. A midterm block fits 4 weeks; a thesis or long self-study plan fits Ongoing.

Commity only counts minutes inside the place you pin, so it works best for somewhere you have to go: a library, reading room, café or co-working space. Getting out the door is usually the hard part, and that is exactly the part Commity checks.

Yes. The free plan covers three commitments, and stakes start at $5. What matters is that it stings a little, not the size. Show up and you pay $0. Premium ($4.99/month) is only for running more than three goals at once.

Yes. Add friends in your profile and the leaderboard switches to just your circle, ranked by Grit from the days you each showed up. Everyone keeps their own stake and their own spot.

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: the free plan runs three commitments at a time with a 51% comeback. You add a card when you start a commitment so a stake can back your goal, but you're charged $0 for as long as you show up on your scheduled days. Premium is optional at $4.99/month and adds unlimited commitments, a 66% comeback, three Journal posts a day and a checkmark by your name.

Premium is $4.99/month and adds unlimited commitments at once (free runs three), a 66% comeback instead of 51%, three Journal posts a day instead of one a week, and a checkmark by your name. What you don't win back after a miss is donated each month to a charity you pick (UNICEF, WWF, Helen Keller Intl or Doctors Without Borders, or one you suggest), and you get the charity's receipt by email. In a duo challenge, a missed stake goes to charity in full (less card fees) instead of 75%. It's billed by the App Store or Google Play and you can cancel anytime. Compare Free and Premium.

Challenge a friend with a link or a code. You each make your own pact with your own stake, and both end on the same Sunday. The first to miss a scheduled day pays a charity the other one picks, never the friend: 75% of the missed stake on the free plan, or all of it minus card fees on Premium. Duos run on fixed terms of 1 to 12 weeks, there’s no comeback in a duo, and no money ever moves between users.

Yes. On the goal step, switch to Just one day and pick today or tomorrow. It works like any pact, with the same GPS check-in and stake, and it ends on its own at midnight. Today is only offered while there’s still time to hit your goal. Miss it and the usual 5-day comeback opens.

Tap I’m here anyway. GPS works without a data connection, so Commity still checks you’re inside your spot, times the visit on your phone, and syncs it as soon as you’re back online. A basement gym or a library with thick walls won’t cost you a day.

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 back 51% of the charge on the free plan, or 66% with Premium. Commity punishes a slip lightly and rewards the return.

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 up to 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.

You choose when you create it: just one day (today or tomorrow), 1, 2, 4, 8 or 12 weeks, or Ongoing. A fixed term counts the week you sign up as week 1, ends on its own on its last Sunday, and can't be cancelled early, which is the point. A one-day pact ends at midnight. An Ongoing commitment renews every week until you cancel, and a cancellation takes effect that Sunday. You're only ever charged for a scheduled day you missed.
