Questions, answered.

A movement game for people who sit for a living. Short sets your phone's camera counts, small wins between meetings, a trail to climb and a streak that forgives a busy week. Lose weight, get stronger or just feel better. No gym needed.

See every feature

Your phone, a chair, a wall and a little space beside your desk. No gym, no weights, no watch.

No. You can play on your own without one. Sign in with Apple or Google to join leagues, crews and clubs, and to keep your progress in your account, so a new phone or your other phones get it back.

Moves made for a desk day, each a ladder from gentle to harder: chair squats, squats and slow squats; wall, desk and knee push-ups, push-ups with your hands on a stair, and full push-ups; desk planks, knee planks and planks; the wall sit; and hip hinges, good mornings and hands-up good mornings.

Every move has a guide with a wordless video, three steps, the muscles it works and its sources.

Count by tapping, with a timer for holds. A tapped set is a small win toward your streak. Sets the camera counts also earn XP and count in leagues.

Nudges come in your work hours and fit around your meals and bedtime. With Skip my meetings on, a nudge waits until your meeting ends; only start and end times are read, on your phone. Quiet hours hold alerts until they end, and you can pause everything for today.

Yes. You set your work days, your work hours and the day your week starts. Water works in ml or fl oz, weight in kg or lb, and height in cm or ft. Ramadan mode works out suhoor and iftar times for your city, on your phone.

Tell the morning check-in, and Sitbuster backs off: sore muscles rest, and pain pauses those moves until you say it's gone. It's a game, not medical advice: if pain doesn't pass, stop and see a doctor or physiotherapist.

Yes. The move break has a seated set, seated moves count as moves, and timers say "Walk or wheel". In a wheelchair, put the brakes on first. You can also tell Sitbuster to go easy on your knees, back, wrists or shoulders.

Before your first set there's a short health check that follows exercise guidelines. When you have a warning sign, it suggests checking with a doctor first, and it adds follow-ups for things like blood pressure, low blood sugar or pregnancy. Small wins are for feeling better, not treatment: if you have a health condition, follow your care team.

No. Fixed rules, run on your phone. Not AI. Each Monday it looks at how your sets felt, your mornings and your days, and every change comes with its reason.

No. Sitbuster never counts calories. Weight goals are for adults only, your weight is never ranked, and it only goes on a share card if you switch that on for the card.

A camera set, or a few different small wins with a move among them. The streak sheet shows what today still needs.

A freeze covers it, if you have one saved. You earn freezes as you level up, and they're never sold. Planned rest days count anyway, Away pauses the streak when life gets in the way, and after a break you get a way to earn your days back.

Your targets grow as you get stronger, and each change comes with a reason. When a move feels easy, the next rung is offered; when it feels hard, an easier one. A harder rung is only ever offered. You choose.

No. To count reps, the app reads your body's position on the phone. Each camera frame is read in memory and dropped. Nothing is recorded, saved or uploaded.

Without an account, nothing about your game. If you sign in, the server keeps your name, your email address, the XP you earn each day for leagues and crews, and a copy of your progress and settings.

Your health answers and steps join that copy only after your yes to Sync health answers, and Ramadan settings only after their own yes. No ads, no analytics, no tracking. Nothing is sold.

In the app, go to You, then Settings, then Delete account. Without the app, use the account deletion page. Deleting your account doesn't cancel a subscription: cancel it in your App Store or Google Play settings.

Players in your league see your name in the form you chose, your XP and your active days, and your steps and small wins only if you show them. You're only placed in a league after you say yes on day 3, and you can choose "Just me" any time. Leagues are for adults, 18 and over.

Everyone in a workplace club sees the same page, owners too. There are no reports, exports or "who's quiet" lists. You choose how the club sees you: Rank only, Name and rank, or Count me quietly, and nobody is told when you change it.

There's no free-text chat. Crews send high-fives, and friends and crewmates can send one of six fixed nudges, like "Stretch break?" or "Walk with me?". Anyone can turn nudges off, and you can report or block any player.

Yes. Free stays free: every move, the daily loop, your streak and freezes, 15 trail chapters, leagues, crews, and one coach change a week. No ads.

Everything that's free · What Plus adds

The price shows in your local currency, in the app and on the App Store or Google Play, before you pay. Plus is monthly or yearly. The yearly plan starts with 7 days free, and we remind you the day before the trial ends; monthly has no trial. Cancel any time in your store settings.

Yes, with Plus. Your own nudges are reminders in your words, at your time, on your days: "Call Mom", every Sunday at 18:30, say. They come every week on top of Sitbuster's planned nudges. If Plus ends, they stop but stay saved.

Your own nudges

No. Freezes are earned, never sold, not even in Plus.
