Every time you reach for Instagram, ScrollToll asks one question first. Get it right and you scroll. Miss it and it comes back later. You're studying — without choosing to. **BUILT ON DISTRIBUTED RECALL™** The same spaced-repetition science behind every serious study tool (Cepeda et al., 2006), delivered where you actually pick up your phone. Cards you struggle with surface more often. Cards you've mastered get out of your way. You don't have to remember to open the app — you already do, 96 times a day. **ANKI ONLY WORKS WHEN YOU OPEN ANKI** We work because you open your phone. Move to China and you'll learn Chinese without trying — you can't help it. ScrollToll does the same thing for the MCAT (and SAT, USMLE prep, mental math, vocabulary, chess, and any topic you want to learn passively). **HOW IT WORKS** 1. Pick the apps that waste your time 2. ScrollToll locks them behind a single question 3. Solve it — usually an MCAT question, mental math problem, chess tactic, or vocabulary card 4. Get 5 minutes, then it relocks automatically 5. Every unlock IS a study session — distributed across your real day **WHO IT'S FOR** - Premeds prepping for the MCAT who want discipline they can't fake - Med students grinding USMLE Step 1 - Students who open Instagram "for a second" and lose an evening - Professionals who lose hours to their phone during deep work - Anyone who's tried Anki, fallen off, and wants the spacing without the discipline tax **THE MATH** The average person unlocks their phone 96 times per day. ScrollToll turns 50+ of those into deliberate, spaced-practice moments. In a month, you've passively practiced over 1,400 questions — without ever sitting down with a textbook. **REAL BLOCKING, NOT A SUGGESTION** ScrollToll uses Apple's Screen Time API to block apps at the OS level. No overlay you can swipe away. No "are you sure?" button. When an app is locked, it's locked — until you earn your way in. - OS-level blocking — can't be bypassed or dismissed - Distributed Recall™ — adaptive spaced repetition built into every unlock - Auto-relock after 5 minutes — no honor system - MCAT, USMLE, mental math, chess, vocabulary, and custom packs - 3 difficulty levels — beginner to advanced - Works with any app — social media, news, dating apps - On-device puzzle delivery — your usage stays private ScrollToll doesn't ask you to quit your phone. It asks you to earn it. Download free. Upgrade for advanced packs, Distributed Recall™ across all topics, and unlimited app blocking.

While getting set up was a little intimidating, once you get started, it’s really helpful! It helps me keep track of my doomscrolling habit, and it’s a really nice way to review content and concepts. Great app ### 2/5 — Great until it wasn’t *2026-08-09* For a few days, this app was everything I’d hoped it’d be. But turns out that that’s just the free trial of the paid version, of which the app is basically useless without. I’d be interested in trying it again if this got resolved, but until then I can’t recommend it. ### 5/5 — A big fan of this work in progress *2026-08-06* I love this app! The developer is clearly working very hard on this and I use it a lot. That being said, the multiple choice can present some challenges on here for me in terms of memorizing the beginning of the answer/question and it would be really cool to see some short answer or jeopardy style questions to facilitate some deeper learning (maybe thats just me though 😂) Theres a good range of topics that already have questions decks and you can import your own too! I was a little bummed that I no longer saw NCLEX questions but otherwise fantastic so far. I pay for premium and feel its worth the (quite low) cost :) ### 5/5 — Helping the doomscrolling *2026-07-27* So happy I found this. It is really just what you need to help you stop doomscrolling and actually think about your goals and get back to studying. ### 1/5 — Paywall??? *2026-07-27* After about a week, the app suddenly limited me to one puzzle per hour and locked me out completely, I couldn’t even leave the payment screen to use the rest of the app. This wasn’t mentioned when I downloaded it. I understand needing to monetize, but springing a hard paywall on users with no warning, and trapping them on the payment screen with no way out, is just bad way to do it. ### 5/5 — ADHD life hack *2026-07-24* For my fellow medbros with attention span issues (most of us, don’t even lie about it) it’s great for when you’re allergic to sitting down long enough for a traditional Kaplan study session. Highly recommend- though you may want to have another more traditional study plan to supplement :) happy studying! ### 5/5 — 2nd Uworld *2026-07-22* Designed incredibly well, this app allows you to fit in a couple of reps every time you open social media. since it’s only one question, it’s not taxing at all. before you know it, you’ve done at least 30 q a day ### 4/5 — Good App with One Downside *2026-07-18* I really like this app and it teaches a lot of randomized MCAT questions. I like the setup and it shows you how many you got right vs how many you got wrong and explains it VERY well and shows you what subjects you need the most help in, HOWEVER. This app is not truly a free app. After consistently playing you are paywalled to practice questions. You have an hour cooldown to answer 1 question and have to pay for the premium subscription to continue studying. This also means your apps stay locked for an hour unless you pay extra… so it defeats the purpose of the app. I’m not sure if this is because I primarily use the app for studying as opposed to a doom-scroll blocker but yeah. ### 5/5 — Helpful *2026-07-17* Don’t have premium but still love the app! It refreshes on some of my prior classes and goes into topics I haven’t yet studied ## Frequently asked questions about ScrollToll ### How does ScrollToll work to help me study?

Smaller screens, no more guessing what the card is covering. ## Apps similar to ScrollToll | App | Rating | Price | Category | | --- | --- | --- | --- | | [Clema: Screen Time Companion](https://appshunter.io/ios/app/clema-screen-time-companion/id6753151263) | 4.8 (990) | Free | Productivity | | [AnkiLock](https://appshunter.io/ios/app/ankilock/id6748466549) | 5.0 (10) | Free | Productivity | | [Friend Controls: Screen Time](https://appshunter.io/ios/app/friend-controls-screen-time/id6651826679) | 4.7 (559) | Free | Productivity | | [Pebble AI: To-Do & Focus](https://appshunter.io/ios/app/pebble-ai-to-do-and-focus/id6746818767) | 4.3 (56) | Free | Productivity | | [breakfree: screen time control](https://appshunter.io/ios/app/breakfree-screen-time-control/id6755940453) | 4.5 (114) | Free | Productivity | | [Scroll Toll: Screen Pledge](https://appshunter.io/ios/app/scroll-toll-screen-pledge/id6741488055) | 5.0 (17) | Free | Productivity | --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
