Rotproof turns your scroll time into a battery. Your feeds stay locked. The battery charges while you're away from them, and you spend it when you want to scroll. When it's empty, it's empty. Go outside. HOW IT WORKS • Pick the apps that eat your day. Rotproof locks them with Apple's Screen Time. • Every minute away from your feeds charges your scroll battery. • Craving the feed? Pick 5, 15 or 30 minutes and scroll guilt-free. • A Live Activity counts down on your lock screen. When time's up, the apps lock again. CHARGE IT 2× FASTER Start a session for the gym, studying, focus time or a good book. Real life charges your battery twice as fast. Lock your apps for the whole session if you want zero temptation. SEE YOUR BRAIN BOUNCE BACK Progress shows how much you really scrolled, when you scroll most, how long your unlocks last and how much time you charged offline. The battery calendar shows every day at a glance. YOUR DATA STAYS YOURS Rotproof uses Apple's Screen Time API. Apple gives us the apps you pick only as encrypted tokens, so we can't see which apps you chose, and your Screen Time data never leaves your device. We only collect basic in-app analytics, like how long you unlock for, to make Rotproof better. Rotproof is a self-control tool for you, not a parental control app. SUBSCRIPTION Rotproof Premium is an auto-renewing subscription. Payment is charged to your Apple ID at confirmation of purchase. It renews automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel any time in your App Store account settings.
