The brutally simple alarm that won't stop until you actually move. No snooze button. No excuses. Just 30 seconds of walking to dismiss.
The Silent Killer
You know you should move more. But when you're deep in work, hours disappear. The research is clear: prolonged sitting is destroying your body.
People who sit for 8+ hours daily have a 40% increased risk of death compared to those who sit less than 4 hours.
Sedentary behavior is associated with a 147% increase in cardiovascular disease events and 90% increase in cardiovascular mortality.
Sitting for extended periods doubles your risk of depression and anxiety. Movement literally changes your brain chemistry.
Prolonged sitting reduces blood flow to the brain, causing cognitive decline. Short movement breaks restore focus and creativity.

Brutally Simple
Set your work hours. Forget about it. Sitless handles the rest.
During your work hours, you'll get random alarms every 20-90 minutes. No predictable schedule means you can't "time" your breaks to avoid them.
The alarm only stops when your phone's sensors detect real movement. Walk around for 30 seconds. That's it. No button to tap, no way to cheat.
Movement complete. Back to your desk with better blood flow, clearer thinking, and zero guilt. Repeat 8-10 times throughout the day.
No Nonsense
We removed everything that doesn't help you move more.
Uses accelerometer and pedometer together. Can't be fooled by shaking your phone on the desk. You actually have to walk.
Alarms cut through silent mode and Do Not Disturb. Because your health is more important than that Slack notification.
Set your schedule once. Sitless only runs during your work hours, on your work days. Evenings and weekends are yours.
One tap to pause for 30 minutes while driving. No penalty. Your safety comes first.
See your completion rate over the past week. No leaderboards, no social sharing. Just you and your data.
All motion data stays on your device. We track app events for improvement, never your movements or location.

"Sustained movement required. No stopping allowed."
Real Users
"I've tried every productivity app. Standing desk reminders, Pomodoro timers, fitness trackers. This is the only one I can't ignore. It's annoying in the best way possible."
"My back pain is gone. Not reduced—gone. Turns out the solution wasn't an expensive chair or standing desk. It was just moving every hour. Who knew?"
"The meeting mode with debt is genius. Yes, you can skip an alarm during a call. But you'll pay for it later with extra steps. It's accountability without judgment."
"I was skeptical about another health app. But there's no gamification, no streaks to maintain, no social pressure. It just makes you move. That's it. That's the whole app."
"My Apple Watch tells me to stand, and I ignore it. Sitless doesn't give you that option. The alarm keeps going until you physically get up and walk. Brutal. Effective."
"Started on Gentle, now on Hardcore. The progress decay is addictive in a healthy way. You can't stop moving or you lose everything. It's the Dark Souls of health apps."
