Dopamine should cost effort. Your phone gives it away for free. That's why you can't stop scrolling, even when you want to. EarnScreen makes cheap dopamine expensive. Block the apps stealing your time β and earn minutes back through real effort. Push-ups. Squats. Steps. Math challenges. The price is set. No bargaining with yourself. SUBSCRIPTION REQUIRED FOR FULL ACCESS EarnScreen is free to download. Core app blocking, exercise tracking, AI rep counting, streaks, and unlimited unlocks require an active auto-renewable subscription or lifetime purchase (pricing shown in the app before you subscribe). A free trial may be available for eligible plans. WHY IT WORKS WHEN NOTHING ELSE DID Native Screen Time fails because ignoring it is free. One tap and you're back. Willpower runs out. App blockers feel like punishment. This is different. You don't fight your phone. You pay for it β with your body or your mind. Every minute of scrolling has a cost. Every cost makes you stronger. HOW IT WORKS 1. Choose the apps you want to control. 2. When you try to open them, they're locked (Premium). 3. Earn coins through effort: push-ups, squats, steps, or math problems (Premium features as marked in the app). 4. Spend coins to unlock screen time. Or close the app and move on with your day. The exchange rates are fixed. You can't lower the price. You can't trick the system. That's the point. WHAT YOU GET (with an active Premium subscription) β Less screen time. Many users aim to cut 2β3 hours per day. β Stronger body. Push-ups, squats, and steps tracked with AI rep counting (Premium). β Sharper mind. Math challenges before you scroll (Premium). β A new relationship with your phone. You own it. It doesn't own you. Results vary. Features above require a separate in-app purchase; see the paywall for current plans, duration, and price. WHO THIS IS FOR This is a discipline tool, not a wellness app. It's built for people who are tired of losing hours to their phone and ready to do something about it. If you want gentle reminders and motivational quotes, this isn't for you. If you want friction that actually works, you're in the right place. WHAT USERS SAY "Lost 4kg in 2 months. The app made me train without me noticing." "I used to fight my phone. Now I just pay it with squats. It's not even hard." "Tried every screen time blocker. This is the first one that actually works because you can't cheat it." DOPAMINE THROUGH EFFORT Cheap dopamine made you weak. Earned dopamine makes you strong. Download the app, see subscription options in the app, pay the price, get your time back. β Privacy Policy: https://earnscreen.com/privacy-policy Terms of Use (EULA): https://earnscreen.com/terms Privacy: We don't sell your data.
