4Hack - 集中を開放する

"4hack" is a completely new digital detox app that restricts and manages the use of specific apps on your smartphone by using a physical NFC tag as a key.

It helps reduce the time spent on social media and video apps, allowing you to dedicate more time to things you truly want to focus on.

[Main Features]
・Register NFC tags as "keys"
Register your existing NFC tags with this app. This will be the sole key to start and release restrictions.

・Freely select apps to restrict
Select the apps you want to restrict from the list and set them as restricted.

・Strong usage restriction activation and deactivation
Touching the registered NFC tag to your smartphone will start the restriction on the target app.

Touching the same NFC tag is required to deactivate the restriction. This prevents easy deactivation by keeping the physical key away from you.

・Reliable restriction persists even after restarting
The restriction status is maintained even after restarting your device.

[Required Permissions]
The following permissions are required for this app to function correctly.

* Permission to access usage: Used to detect when a restricted app is launched.

* Display over other apps: Used to display a screen blocking the use of a restricted app when it is launched.

[Important Notes]
To use the main functions of this app, you will need a commercially available NFC card and a smartphone that supports NFC reading.
This app detects app launches by running in the background. Depending on your device's power saving settings and memory management status, the restrictions may not function correctly. If you are unsure whether it will work correctly on your device, please check beforehand.
