## What is Hirake?

Hirake is a focus app that locks the apps you open out of habit—social media, games, anything—and only unlocks them once you answer a quiz correctly. It combines Screen Time limits with real study, turning the time you mindlessly scroll into time you spend learning.

■ Key features
・Lock the apps you choose. To unlock them you have to answer a set number of quiz questions correctly.
・Includes question banks for certification exams, organized by year.
・Question banks are cached on your device, so you can answer and unlock even with no connection.
・After unlocking, you can use the app for the time you set. When it runs out, it locks again automatically.
・Check your daily quiz count and accuracy in the Stats tab. Your progress is clear at a glance.
・A minimal black-and-white design built to keep you focused, not distracted.

■ Great for you if you want to
・Cut down the time you spend on social media and video apps.
・Keep studying for certifications in spare moments.
・Stick to app limits that willpower alone never kept.
・Use it as a kind of parental control.

■ How it works (privacy)
The locking is powered by Apple's Screen Time / Family Controls. We never collect a history of which apps you open. Only downloading question banks and account features work online; everything else is completed offline.

More question banks are on the way. Rebuild your study habit and a healthier relationship with your phone, with Hirake.
