Description

"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.
