Sparky makes screen time feel intentional, not forbidden. Do one small real-life win, earn Scroll Energy, then spend it through Time Bank to open the apps and categories you choose. Most blockers just say no. Timers nag you to stop at the worst moment. Sparky flips it around: do the thing first, then scroll on purpose, guilt-free. HOW IT WORKS 1. Pick your daily wins. Move, read, focus, drink water, wind down, or build your own. 2. Choose your App Gates. The apps and categories that pull you into autopilot wait behind a gentle gate. 3. Earn Scroll Energy. Every check-in tops up your bank. 4. Spend on purpose. Start Time Bank when you are ready, and the minutes you do not use come straight back when you stop early. WHY SPARKY IS DIFFERENT - A warm companion, never a nag. Sparky celebrates your wins instead of shaming your slips. - App Gates powered by Apple Screen Time, all on your device. - Daily budgets, Auto-Gates, and per-app limits you actually control. - Streaks, history, and gentle insights that show your time getting calmer. - Widgets, Shortcuts, and Live Activities for one-tap Time Bank. - Unlock new Sparky worlds and app icons as your streak grows. Sparky is for people who still love their favorite apps and just want a better trade: one small real win before the feed. PRO (OPTIONAL) The core loop is free, with no account to create. Upgrade to Pro to run more than five habits at once, plus advanced rules, deeper history, and export. Pro is available as a monthly or yearly subscription, or a one-time lifetime unlock. Payment is charged to your Apple Account at confirmation of purchase. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period, and you can manage or cancel them anytime in your Apple Account settings. PRIVACY Your habits and Screen Time data stay on your device. Screen Time access is optional and you can change it anytime in Settings. Try one tiny win before your next scroll.
