HOW IT WORKS

Willpower fades.
A locked app doesn't.

PrepScroll runs quietly in the background using Apple's Screen Time. Setup takes a couple of minutes, and then every break you take starts with a little practice.

    Your apps lock

    Pick the apps that eat your evenings. When your earned time runs out, they lock.

  2. 2

    You answer three questions

    A short round of real-format SAT & ACT practice, with an explanation for every answer.

    Your feed comes back

    Correct answers turn into minutes. Scroll guilt-free, then earn the next break.

Questions

Something else? Visit support or email prepscrollapp@gmail.com.

Can I still get calls and texts?

Yes. You choose which apps to lock. Keep Phone and Messages on the Always Allowed list in iOS Settings so they're never blocked.

Which apps can I lock?

Any app you choose — most people start with Instagram, TikTok, YouTube and Snapchat.

Is this official College Board material?

No. Questions are modeled on real exam formats, but PrepScroll isn't affiliated with, endorsed by, or sponsored by the College Board or ACT, Inc.

Can parents set it up?

Yes. PrepScroll works with Apple Family Sharing, so a parent or guardian keeps oversight through Apple's parental controls.

How do I cancel?

Anytime, in Settings → Apple ID → Subscriptions. You keep access until the end of the current billing period. Deleting the app doesn't cancel the subscription.
