Your phone is always right there. One tap and you're back in. Thumb Scroll flips it: do something in real life first, then scroll. Block the apps that steal your time β€” TikTok, Instagram, YouTube, games, any app you pick β€” and unlock minutes only after you've earned them. HOW IT WORKS 1. Pick the apps (and sites) to block 2. Do a real action: make your bed, touch grass, drink water, read a book… 3. Snap a photo: AI verifies it and gives you coins 4. Spend coins to unlock minutes on your blocked apps No coins? Apps stay locked. Simple. You don't have to delete your favorite apps. You just have to do something first. WHY IT WORKS (where blocking alone fails) Other apps just say "stop." But your phone is one tap away and you cave. Thumb Scroll gives you a trade instead: a walk for TikTok, a book for Instagram, a glass of water for two minutes of scroll. Your phone comes after life, not instead of it. WHAT'S INSIDE β€’ App & website blocking via Apple's Screen Time API β€’ Coins earned with real actions, validated by photo + AI (no cheating) β€’ 7 daily actions + Object Hunt: find an object with your camera β€’ Store: turn coins into minutes β€’ 3 difficulty levels (Light, Balanced, Intense) that change the coinsβ†’minutes rate β€’ Bedtime & wake schedule + custom time rules (days and time slots) β€’ Daily and weekly reports, a 0–100 score, day streaks β€’ Your thumb mascot: happy when you unplug, worn out when you scroll too much PRIVATE & SECURE Thumb Scroll uses Apple's Screen Time API: all monitoring and blocking run entirely on your device. Your usage data never leaves your phone. EARLY ACCESS Thumb Scroll is in early access: every feature is available for free, no subscription. Jump in and help us make it better. Less scrolling.
