Multiple strategies to reduce your screentime 1. Delay before opening your app: A bit of time before choosing if you need to open your distracting app. You can have the wait time increase each time you open your app. 2. Interrupt your scrolling: Check your distracting apps for short periods of time so you don't get sucked in. 3. Set an app goal and optionally block when you reach your limit. 4. Configurable for different days of the week and time by app. 5. Messages like "Is this important" before opening your app. 6. See your screen time for only your distracting apps. Don't worry about Google Maps bloating up your time. 7. Strict block your apps: Either for time ranges, after a certain number of opens or ScreenTime. 8. Locks on Settings to prevent you from changing your settings when you want to open an app. 9. Breathing and other activities to encourage you not to need to open the app while waiting for it to unlock. 10. Streaks to encourage you not to exceed your limits or override your settings.

Take back your day with Shelly — your friendly screen time coach to help you build healthy phone habits. Shelly is a cute snail who lives on your phone. The less you doom-scroll, the healthier Shelly gets. The more you mindlessly scroll, the more Shelly retreats into her shell. It's a simple visual nudge that works — no guilt trips, no lectures, just a little friend keeping you honest. Most of us spend 5+ hours glued to our screens without realizing it. Shelly flips the script: block the apps that drain your time, set focus schedules, and get gentle breathing reminders when you're about to spiral into another scroll session. WHY SHELLY WORKS - Visual motivation: Watch Shelly's health improve as your screen time drops - Gentle nudges, not guilt: Breathing exercises instead of harsh lockouts - Smart schedules: Auto-block apps during bedtime, work hours, or study sessions - Shell Mode: Total focus mode that blocks everything except what you whitelist - Real insights: See exactly which apps eat your time and track your progress FEATURES - Instant App Blocking: Pick the apps and sites to block. Done in seconds. - Shell Mode: Block everything except what you whitelist. Total focus. - Breathing Interventions: A 10-second breathing pause before any tracked app opens. - Smart Schedules: Auto-block apps at bedtime, work hours, or custom windows. - Daily Time Allowances: Cap usage on any app. Hit the limit, Shelly blocks it. - Escape Hatch: Need a blocked app? Simple unblock. - Streak Tracking: Stay under your goal. Watch the streak grow. - Home Screen Widget: Today's health score, always visible. - History & Insights: Weekly charts to spot patterns and celebrate wins. DESIGNED FOR - Students who lose hours to scrolling before exams - Creators who need to focus on making, not consuming - Professionals who want deep work without distractions - Parents building healthier phone habits for the family - Anyone who's tired of picking up their phone 150+ times a day PRIVATE & SECURE Shelly uses Apple's Screen Time API. All monitoring and blocking happen entirely on your device. Your usage data never leaves your phone — ever. No tracking. No ads. Just you and Shelly. FOUNDERS NOTE: I built Shelly because I was scrolling for 6 hours a day on my phone and couldn't stop. None of the screen time apps felt right — they were either too strict, too preachy, too complicated, or too easy to bypass. Shelly is the app I wished existed: simple, kind, and effective.
