Store listing

By Yuichiro Honda, from the App Store
Description by Yuichiro Honda Written by the developer, not by AppBrain. Click to read.
No social media in the hour before bed. Videos capped at one hour a day.
Set it once, and Isshin blocks those apps automatically when the time comes.

■ HOW IT DIFFERS FROM IPHONE SCREEN TIME
Built-in Screen Time limits are easy to turn off yourself. Isshin adds a moment of friction right when you reach for your phone out of habit.

• A breathing pause before you can unblock
• Choose from four strictness levels: longer waits, or missions you must clear to unblock. In Deep (Pro), you can't unblock, and you can't delete any app on your iPhone, until the block ends

■ WHAT YOU CAN DO
[FOCUS TIMER]
For when you need to focus now. Pick a duration and tap to lock your apps. The apps you chose stay closed until the timer ends.

[RULES]
Limit apps automatically at the same times every day.
For example:
• Schedule: pause social media on weekdays from 9 PM to 7 AM
• Time limit: short-video apps for up to 30 minutes a day
• Open limit: games up to 5 times a day
• Walk to unlock (Pro): locked until you walk 3,000 steps
Every rule is fully customizable, so you can build ones you'll actually stick with.

[BLOCK MISSIONS (Pro)]
A small task before you unblock: trace a dot, turn your phone, solve a math problem, or copy a passage.

[STATS]
Look back on your screen time trends and the time you've taken back.

■ MADE FOR YOU IF
• Late-night scrolling is cutting into your sleep
• A quick video between tasks turns into an hour
• You keep opening social media while studying for exams
• You've switched off your own Screen Time limits before
• You want to make digital detox an easy habit

■ FREE
• Focus timer (unlimited sessions)
