About
SAT Locker asks you one SAT practice question before you open the apps you scroll the most. Get it right and they open for a few minutes, so the time you already spend on your phone becomes SAT prep.
WHAT YOU GET
- 1,500 original SAT practice questions across all 8 content areas of the digital SAT, so you practice Math and Reading and Writing evenly
- An explanation after every answer, so you learn from the questions you miss
- A study plan toward your goal score and test date, so you know where you stand each day
- A projected score estimate that updates as you answer, so you can see your progress
- A review list with the questions you got wrong, so they come back until you get them right
- A daily streak, reminders and a countdown to test day, so you keep practicing every day
HOW THE LOCK WORKS
SAT Locker uses Apple's Screen Time on your own iPhone. You pick the apps in Apple's picker, and Apple keeps that list private, even from us. When you open one of them, tap Answer a question, answer it in SAT Locker, and the apps open for the minutes you chose. You get one emergency pause a day.
SUBSCRIPTION
SAT Locker is free to download. The questions, the study plan and the projected score need a subscription: 3 days free, then $29.99 per month. Payment is charged to your Apple ID when you confirm the purchase. The subscription renews automatically unless you cancel at least 24 hours before the end of the current period. Manage or cancel it in your iPhone Settings, under your name, then Subscriptions. When your subscription ends, SAT Locker removes the lock from your apps.
The projected score is an estimate, not an official score. SAT® is a trademark registered and owned by the College Board, which is not affiliated with and does not endorse this product.
