About this app

"moku" comes from the Japanese word "moku," meaning silence, stillness, and concentration.

First thing in the morning, while your mind is still groggy, you reach for your smartphone. During work breaks, you glance at social media. Before going to sleep, you find yourself watching videos for an hour without realizing it. These small things add up, gradually eroding precious time.

It's difficult to effectively distance yourself from your smartphone through willpower alone. moku is a quiet ally that protects your concentration through a "system," not willpower. While all functions work with the app alone, using the NFC gadget "moku device" (optional, sold separately), which is unique to moku, can further enhance your concentration. Why not reclaim your time?


◆ Recommended for those who:

・Are aware of their smartphone addiction and want to reduce screen time

・Want to concentrate on reading or studying but keep checking notifications

・Want to regain focus while working from home

・Want to stop mindlessly using their smartphone before bed and get quality sleep

・Want to make digital detox a habit

・Have not been able to stick with other concentration apps or app restriction features

◆ Block SNS, games, and videos all at once with one tap

X (Twitter), Instagram, YouTube, TikTok. Block all the apps that bother you at once and create time to concentrate only on what's in front of you. If you try to open an app while it's blocked, moku will gently stop you saying, "Now is time to concentrate." You're not scolded, you're watched over. That's moku's blocking.

◆ A small character, "moku," that accompanies your concentration

During concentration sessions, a character named moku appears on the screen. It spends its time leisurely in a 3D room, breathing and walking around.

Concentration time becomes not a matter of "endurance," but a "peaceful time" spent with moku. That's the experience moku aims to provide.

◆ Modes that can be switched for each scene

A standard "Reading Mode" is available. When you want to concentrate on a physical book, you can block out distracting apps and immerse yourself in the world of the book.

In addition, you can freely create your own custom modes. You can save and use multiple block settings for different purposes, such as "Morning Study Mode," "Evening Writing Mode," and "Weekend Digital Detox." Each mode is assigned a different room, and the scenery changes each time you switch.

Even during a session, you can switch the blocked items by simply tapping the mode name. The timer doesn't stop, so you can freely switch between reading and studying, or work and reading, according to your mood.

◆ Lights Off Mode – Put down your smartphone and let moku sleep

In Lights Off Mode, which dims the screen, you can achieve even deeper concentration.

If you quietly put down your smartphone, moku will sleep soundly. However, if you move the smartphone, moku will be startled and wake up. Because you don't want to wake it, your hand naturally puts it down.

It creates time away from your smartphone, much like watching over a small pet.

◆ A unique option only moku offers – transcending "willpower" with an NFC device

What sets moku apart from other concentration apps is its physical mechanism: an "NFC device."

Using the separately sold moku device (an NFC-enabled bookmark), you need to touch the device to end a concentration session. In other words, concentration cannot be interrupted unless the device is at hand. It overcomes the weakness of giving in to self-doubt ("just 5 more minutes...") not through willpower, but through a system.

Of course, all moku's concentration features are available even without the device. The app itself works for everything: blocks, timers, and characters. The device is an advanced option for those who "just can't maintain concentration with willpower alone."

◆ Visible progress in concentration

Daily concentration time is recorded in a graph. A 100-level system, where your level increases the more you concentrate, visualizes your progress.


Starting with "The First Step," and continuing through "The Beginning of Habit," "The Gateway to Silence," "The Budding of Concentration," "The Door to Immersion"... and culminating in the final chapter, "The Legendary Silence," this 10-chapter story quietly watches over your journey of concentration.

◆ Automatically Start Your Daily Concentration

"No more smartphones at 10 PM every night," "Work mode from 9 AM on weekdays." Using the scheduling function, blocks begin automatically at set times. It also supports daily repetition.

By transforming concentration from a "decision to make each time" to an "automatically starting habit," the hurdle to continuing is significantly lowered.

◆ Incorporate moku into Your Day

In the morning, start with "Reading Mode" upon waking. Instead of social media, you'll have time to open a book by your bedside.

At noon, switch to Concentration Mode when heading to work. You can make progress on tasks you wanted to complete in a few hours free from notifications.

At night, activate Lights Off Mode before going to sleep. Get away from bright screens and prepare for a peaceful sleep.

At every stage of your day, you'll find yourself thinking, "I'm glad I put my phone down."

◆ Data is stored on your device

Session history, mode settings, and schedules are all stored only on your device. No account registration is required, and your concentration records are never sent to external servers.

◆ From the Developer

moku is an app created by an individual developer. A single engineer, who constantly blamed himself for his "weak willpower," meticulously crafted this app to "protect concentration through a system, not willpower."

It's neither a free app full of ads nor a feature-rich overseas app. It aims to be a concentration app that quietly delivers only what's necessary.

It's not your fault that your smartphone steals your time. You can regain your concentration by changing the system. We hope moku can be that small step for you.

Why not try changing how you interact with your smartphone, just a little?

moku quietly supports your desire to "concentrate."

* Fully Japanese UI. English is also available.

* App blocking requires permission for "Access to Usage Data" and "Display over other apps" (there's an explanation screen within the app before granting permission).

* NFC device sold separately and optional. You can use all the focus features without a device.
