Tomosu: Screen Time & Focus
Digital Detox & App Blocker
Free · In‑App Purchases · Designed for iPad
Your phone. Your rules. Tomosu flips screen time on its head — instead of blocking apps, you choose which ones to open. Take back your day, one session at a time.
Stop scrolling. Start living.
You unlock your phone to check one thing — and an hour disappears. Sound familiar?
Tomosu is a digital wellbeing app that takes a radically different approach. Instead of blocking apps after you've already used them too much, Tomosu restricts all apps by default — 24/7. When you actually need something, you start a Focus Session and unlock only the apps you choose. No notifications. No badges. No distractions. Just intention.
— HOW IT WORKS —
1. All apps are restricted around the clock
Notifications and badges are silenced across your entire phone. Your lock screen becomes peaceful again.
2. Start a Focus Session when you're ready
Choose a preset — Work, Study, Social, Reading — or create your own. Only the apps you select become available.
3. Earn coins for staying focused
Complete sessions to earn coins. Use them to unlock beautiful visual themes — Japanese candles, bonfires, lanterns, and more.
— KEY FEATURES —
- 24/7 App Restriction: Every app is locked by default. Notifications and badges disappear completely.
- Focus Sessions with Presets: One-tap sessions for Work, Study, SNS, and more. Customize which apps are allowed.
- Quick Use Mode: Need to check something fast? 15 or 30-minute light sessions, no setup required.
- SNS Challenge: Before opening social media, complete a quick physical challenge — shake your phone, do a breathing exercise, or stretch. A small pause that makes a big difference.
- Coins & Themes: Beautiful candlelight and fire animations reward your focus. The more you concentrate, the richer your world becomes.
- Achievements: Unlock badges for focus streaks, total hours, and session milestones. Each comes with bonus coins.
- Statistics: See your weekly and monthly focus trends, session history, and progress.
- Social Map: See lights from fellow users around Japan and the world. You're not alone on this journey.
- Live Activity & Dynamic Island: See your remaining session time right on your lock screen (iPhone 14 Pro and later).

— PHILOSOPHY —
Most screen time apps punish you after the damage is done. Tomosu starts from zero — a clean, quiet phone — and lets you choose what to let in. It's not about willpower. It's about designing a better default.
Your phone should serve you. Let's make that happen.
