With Dopamine Lock, your brainrot addiction will accidentally made you fit. Dopamine Lock makes you do pushups, walk, or sleep before you can open TikTok, Instagram, or YouTube Shorts. You earn Dopamine Credits for moving your body, then spend them to unlock the apps you actually came here for. 1 pushup = 1 minute of scroll time. HOW IT WORKS • Do pushups in front of your camera. Each rep earns one Dopamine Credit. • Cash out your daily steps. 250 steps = 1 credit. • Sleep 7+ hours for bonus credits. But don't sleep too long, we punish that... • Spend credits to unlock the social apps you locked. • Credits reset at 4 AM. Clean slate every morning. THE BRAINROT RECEIPT When you unlock, you get a receipt. It tells you exactly what you did and what it cost. "47 pushups for 47 minutes of doomscrolling." You can share these if you want. Or not, it's a bit pathetic. WHY THIS APP Scrolling usually makes you feel bad or guilty. This won't fix that, but at least you'll get your steps in too. Real tracking with your camera and HealthKit, all processing done on your phone. WHO SHOULD USE IT • People who open TikTok "for one minute" and surface an hour later. • Anyone who hates productivity apps that lecture them. • People who need to be forced to get fit. A subscription is required to use this app. Terms of Use: https://dopaminelock.app/privacy
