## What is moku・App Blocker & Focus Timer?

"moku" means silence in Japanese. Stillness, focus, a small distance from your phone.

You reach for your phone before you're fully awake. You watch videos late into the night. Small habits quietly take your time away.

Willpower alone isn't enough. moku protects your focus with structure — and uniquely among focus apps, an optional NFC device stands in when willpower isn't enough. Your time, back in your hands.


◆ WHO MOKU IS FOR

- You want to reduce screen time and phone dependence
- You want to read or study, but keep checking notifications
- You need focus during remote work
- You want a phone-free bedtime routine
- Other focus apps haven't stuck for you


◆ ONE TAP TO BLOCK WHAT DISTRACTS YOU

Block Twitter/X, Instagram, YouTube, TikTok — all at once. Try to open a blocked app, and moku gently stops you: "This is your focus time." Not scolded. Watched over.


◆ MOKU — A QUIET COMPANION

During a session, a character named moku appears on screen. A small creature in a 3D room, breathing, walking quietly. Focus becomes "quiet time with moku," not restraint.


◆ ONE PRESET, UNLIMITED CUSTOM MODES

A Reading preset is included. Create your own modes freely: "Morning Study," "Deep Work," "Weekend Detox." Each mode assigns its own 3D room, so the view changes as you switch.

Set what to block by app, category, or website. Switch between "block selected" and "allow only selected."


◆ WEBSITE BLOCKING

Block specific sites, or allow only the ones you choose. No more browser loophole.


◆ LIGHTS-OFF MODE — LET MOKU SLEEP

Darken the screen for deeper focus. Leave your phone still and moku sleeps. Move it, and moku wakes up startled. You don't want to wake them — so your hand naturally leaves the phone.


◆ WHAT SETS MOKU APART — THE OPTIONAL NFC DEVICE

No other focus app offers this: an optional physical NFC device (a bookmark with a built-in NFC tag, sold separately). With it, ending a session requires tapping the device. If the device isn't in reach, you physically can't interrupt your focus.

moku works fully without the device. Every feature — blocking, character, lights-off, timer — runs on the app alone. The device is for those moments when willpower isn't enough.


◆ YOUR FOCUS, MADE VISIBLE

Daily focus time is graphed. A 100-level system across 10 story chapters tracks your growth — from "First Steps" to "The Legendary moku."


◆ AUTOMATIC FOCUS, EVERY DAY

Schedule sessions to start on their own — "No phone after 10pm," "Deep Work from 9am weekdays." Focus becomes a habit that begins without a decision.


◆ MORE

- Dynamic Island & Live Activity — timer on your lock screen
- Gentle reminders when you pick up your phone mid-session
- Switch modes mid-session without stopping the timer
- iCloud sync for history, modes, schedules. No account needed.


◆ WHY MOKU

- Apple's native Screen Time API — few ways around the block
- "Time with a character," not restraint
- Optional NFC device for physical lock-out — uniquely moku
- Freemium — all core features are free


◆ MOKU PREMIUM

Free: one-tap blocking, focus sessions, the character, the Reading preset.

Premium unlocks:
- Unlimited custom modes
- Up to 10 scheduled sessions
- Lights-off mode
- Cheat Lock (prevents app deletion)
- Content Filter (blocks adult content)
- Ad-free experience

Choose Lifetime, Yearly, or Monthly.


◆ FAQ

Q. Does it really block apps?
A. Yes. moku uses Apple's native Screen Time API.

Q. Do I need the NFC device?
A. No. All focus features work with the app alone.

Q. Where is my data stored?
A. Only on your device and your iCloud.

### 4/5 — 制限アプリとしてだいぶ優秀

*2026-08-15*

なんか達成した時とか集中の時間中にキャラクターが成長するとかレベルが上がるとかコインがもらえて背景や家具を購入できるとかマルチで記録を競えるとかなんでもいいのでモチベ要素が増えるともっと最高です。

### 5/5 — とても気に入っています

*2026-07-18*

物理カードがあって初めて、スマホを手放せる効果を感じました！集中モードオンにするオフにするときにアプリを開いてモードをオンにするオフにすると言うステップが発生して少しだけ手間なのでウィジェットとかあれば便利かなとか思いました。アプリ開かなくても物理カードに携帯タップするだけでオンにできるオフにできるみたいな手軽さとかもあると個人的にとてもうれしいです

**Developer response:** いつもmokuをご利用いただき、誠にありがとうございます。
レビューを投稿いただき、誠にありがとうございます！

物理カードもご利用いただけているとのことで、大変嬉しく思っております。開発者冥利につきます。

集中モードの切り替えのたびにアプリを開く一手間については、ご指摘の通りだと感じています。カードをかざすだけでオン・オフが完結する手軽さ、より自然にモードを切り替えられる形を目指して、実現に向けて取り組んでまいります。

ウィジェットの件につきましても、前向きに検討させていただきますので、アップデートにご期待いただけますと幸いです。

今後ともmokuをよろしくお願いいたします。
