ScrollVolt

Your scrolling now has a battery. ScrollVolt is a screen time limit and app blocker that doesn't make you quit your phone. Pick the apps that steal your time – social media, short videos, games, whatever it is for you – and give them a scroll battery. Scroll and it drains. Put the phone down and it recharges. Simple. WHY HARD BLOCKING DOESN'T STICK Most blockers lock everything and hope for the best. A day later you turn them off. ScrollVolt gives you a budget instead: you still get to scroll, just not endlessly. Doomscrolling turns into a choice you make on purpose. HOW IT WORKS 1. Choose the apps you want to limit 2. They share one scroll battery that drains while you use them 3. Drag the battery to unlock exactly as many minutes as you want 4. At zero, a calm shield replaces the feed until it recharges 5. Start a focus session to charge it 2x faster THE HALF CHALLENGE ScrollVolt doesn't ask you to go cold turkey. It lowers your daily limit by 5, 10 or 15 minutes a day until you scroll half as much as you do today. Small enough to stick, big enough to win back hours every week. FOCUS SESSIONS Lock in for a workout, study session or deep work. Every distracting app stays locked for the session, and your battery charges twice as fast while you're away. MEET VOLTY Volty is your little battery buddy. Full of energy when you take breaks, running low when you scroll too much. A friendly nudge, not a lecture. WHAT'S INSIDE • Scroll battery for any apps you choose • Drag-to-unlock minute picker • Calm shield screen when the battery is empty • Focus sessions with 2x charging • Half Challenge to cut screen time step by step • Live battery, daily chart and weekly scroll trend • A log of every scroll and focus session PRIVATE BY DESIGN ScrollVolt uses Apple's Screen Time frameworks. Apple only shares anonymous tokens for the apps you choose, everything runs on your iPhone, and there is no account, no tracking and no ads. Less doomscrolling, more life. Charge up. SUBSCRIPTION ScrollVolt Premium is a yearly auto-renewing subscription with a 3-day free trial. Payment is charged to your Apple Account when the trial ends. The subscription renews automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel any time in your Apple Account settings.
