About App Blocker & Focus - Isshin
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) • 1 rule • Block up to 5 apps • Block screen with a breathing pause • All-time stats ■ ISSHIN PRO • Unlimited rules • Block up to 49 apps, plus categories and websites • Allow list: block everything except the apps you choose • Harder-to-unblock levels (Strict / Intense / Deep) and block missions • Step-based rules with Apple Health • Always-on blocking and adult website blocking • Weekly and daily stats, plus more themes Try Isshin Pro free for 7 days with the annual plan. Start taking back your time today. ■ PRIVACY Isshin uses Apple's Screen Time API. Your Screen Time data never leaves your device, and Isshin can't see what you do inside your apps.
