StudyIn is an SAT/ACT app blocker designed specifically for students preparing for the Digital SAT/ACT. Block distracting apps like TikTok and Instagram, study, then pass Math or Reading & Writing questions to earn your screen time back. Unlike ordinary screen-time blockers, StudyIn combines app blocking with exam-specific questions, adaptive difficulty and mastery tracking. Block distracting apps, study, then prove you've studied by answering questions that are subject-specific and are the type that actually appear on your exam. Pass? You've earned your screen time! Guilt-free scrolling, and no more nagging feeling in the back of your head. Fail? No more coddling, your future is at stake here. Get back to studying and come back once you know your stuff. You can talk yourself into fifteen more minutes. You can't talk yourself into knowing the answer. HOW IT WORKS 1. Choose the apps that have you scrolling for hours. 2. Customise a study session to fit your needs. 3. Actually do some studying (this one is on you). 4. Answer questions from your real syllabus and see if you've earned access to your apps. 5. Pass, and your apps open for a set window. Enjoy your break. Fail, and the shield stays up. There is no negotiating here. A question doesn't care how tired you are or how much 6. you deserve a break. 7. Get back to studying. Repeat this pattern and see a healthy habit form. 8. Ace your exam! 9. Delete StudyIn or use us for your next exam. THE QUIZ IS THE STUDYING This is the part people don't expect. Twenty years of research on retrieval practice found that testing yourself beats rereading and highlighting, which are the two things almost everyone does (Roediger & Karpicke, 2006). Are you starting to get it? The thing standing between you and that dopamine hit is also the thing improving your score. Now you are training yourself to WANT to study. WHAT'S INSIDE - An OS-level shield on any app you choose, built on Apple's Family Controls framework, so it holds across the whole device instead of inside one app. - Questions from real syllabuses: SAT Reading & Writing, SAT Math, ACT Mathematics, ACT English & Reading. - Adaptive difficulty across four levels. Questions get harder as you improve, and the ones you got wrong come back until you have them locked down. - Per-module mastery tracking, so you can see which topics are costing you marks. - Different modes. Study mode for exam season, interval-gated. Casual mode for maintenance, with lives and a daily unlock budget. - An exam countdown, full session history, and a study companion that reacts to how the session is going. WHY IT COSTS What makes this study system work is the questions we put in front of you at quiz time. Too easy, and you don't learn anything. Too hard, and you lose motivation to study. That's why we use a difficulty-adaptive algorithm built on thousands of past-paper questions. This ensures concepts you have learnt are being reinforced, while also pushing the limits of your understanding. Private SAT tutoring runs $45 to $400 an hour. A year of StudyIn costs less than one of those hours and will help you build a study structure across your entire independent study. Unlike a generic free blocker, StudyIn will actually make you study. Psychological research and behavioural economics studies show time and time again that people who pay for a product, service, or program exhibit stronger commitment, completion rates, and perceived value compared to those who receive the same item for free. By paying, you are making a commitment to yourself about your intentions for studying. StudyIn is a subscription with weekly, monthly and annual plans. There is no free version and no ads. Every plan starts with a 7-day free trial, and you are not charged if you cancel before it ends. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Verdict
The clearest difference is rating: StudyIn at 5.0 against Proll's 4.6. StudyIn also leads on update cadence (every 2 weeks vs every 2 months). Proll's advantage is monetization model (free vs free with in-app purchases) and ratings volume (14 vs 1). On price, review sentiment, ads and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Proll sells 2 in-app purchases, starting at $3.99 per 7 days and StudyIn sells 6 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.
StudyIn holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Proll has 14 ratings behind it against 1, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.
Proll ships an update every 2 months, StudyIn every 2 weeks. Both last shipped on October 24, 2026.
