## What is App Blocker & Focus?

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.
