## What is SAT Locker?

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.

## Version history (last 5 releases)

### 1.0.5 — 2026-11-04

Your Home screen now shows a trail of levels from your starting score to your goal.

Start a challenge with friends, share the code, and see who gets the most questions right.

See your week and your wins in one place, and meet the new teacher cat.

### 1.0.4 — 2026-10-29

With a goal of 1400 or more, your plan now gives you more hard questions, and the hardest ones come with a longer, step-by-step explanation.

In the last 30 days before your test, the Plan screen shows what to focus on each day.

If you already took the SAT, you can enter your Math and Reading and Writing scores. Your plan starts with your lower section, and the Plan screen shows each attempt and your superscore.

### 1.0.3 — 2026-10-29

The screen where you start your plan now opens with your goal score and test date, and the list of what the plan includes is shorter.

The 12-month plan offer shows what it costs per month and how much you save compared with paying every month. The practice tests offer has a shorter description.

If your plan is paused, the Home screen shows how many questions you answered and has a button to restart your plan. Your answers and your review list stay saved.

Some of the text in the first-time setup is clearer.

### 1.0.2 — 2026-10-27

You can now switch from the monthly plan to a 12-month plan with one payment, in Settings, Subscription.

You can buy 2 full-length practice tests with the same sections, number of questions and time limits as the digital SAT. Each one ends with a score estimate.

Math focus and Reading and Writing focus add 200 new questions for each section, included in your plan. Math explanations show how to solve each question in Desmos, and Reading and Writing explanations name the rule the question tests.

### 1.0.1 — 2026-10-25

New App Store screenshots and description. The app itself works the same as in version 1.0.
