## What is Screen Time & Focus?

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).
- Widget: Start sessions and check your status from your home screen.

— PREMIUM —

Free to use with no ads. Premium unlocks:
- 3x coin multiplier
- Exclusive visual themes
- Detailed statistics

— 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.

### 3/5 — 設定できない

*2026-08-12*

とても良いと思います。ただ、アプリを登録しようとしても検索しても出てこないアプリもあります。なのでそのアプリは仕方なく24時間解除にするしかありません。ジモティーなどは出てきませんでした。なぜ？

### 5/5 — スマホの利用時間記録にもいい

*2026-04-16*

SNSにどのぐらい時間を消費しているか記録したくて使い始めました。

セッション開始時に、時間を指定してからアプリロックを解除するという仕組みが、消費時間の意識づけになってとても良い体験になっています。

使い方でわからなかったのが2点ほど。

ヘルプには自分専用のプリセットも作れると書いてありましたが、作り方がわかりませんでした。

また、セッション時間を5-120分まで設定できると書いてありましたが、実際には最小15分までしか設定できずそれ以下にはできませんでした。

どちらもプレミアムを購入すれば使えるのかな？

2026.04.16 追記

薪ストーブ（テーマ・サウンド）の追加、楽しみにしてます！

### 5/5 — 世界を変える本気のアプリ

*2026-03-02*

ここで開発者本人がレビューをしてしまって良いものか分かりませんが、一番のユーザーであり、かつファンであるという変人なので勝手にレビューしてしまいますw

このアプリは、現代のスマホ依存を根本から解決してくれるであろう画期的なアプリとなっています。スマホやSNSの仕組みそのものを変えてしまうため、習慣的にダラダラと見続けてしまうことがなくなります。

実はこのアプリ、5年の構想と、半年間の開発期間を経て作り上げました。半端な気持ちで作っておりません。悩みに悩み抜いて考えが熟成されて、旨みだけが残りました。そんなアプリをぜひ一度試してみて欲しいです。使い方が分からなければここのレビューでも、個人宛のメールでも良いのでぜひお問い合わせください！必ず返信いたします。

基本は無料で使えますし、広告なども一切表示されません^^

これからもまずは僕のために。その次にみなさまのために、この人生をより有意義で楽しいものにするためにご提供いたします。
引き続きアプリを改善して、より盛り上げていきたいなと思っております。
どうぞよろしくお願いします。
