ScrollToll locks Instagram, TikTok until you answer an MCAT or TEAS question. Practice every time you unlock — no app to remember to open.
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.

Solid app - and I say that as someone burned out on Kaplan and UWorld. The hook is your distraction apps are locked behind a study question, so you either study or stay off Instagram. Either outcome is a win honestly. The mechanic actually works because you can't just dismiss it. Small note that the questions could use more difficulty variation / matching in some packs but otherwise really solid.
Developer Response
Thanks for this. The difficulty-variation note is fair - tighter difficulty matching within some packs is on the list and actively being worked on. Appreciate you giving it a real shot, and good luck with the prep.
Awesome

I have a bad habit of forgetting to use the study apps. This eliminated that problem. It has helpful explanations and also super fair premium price. Not a price gouge like a lot of study tools are. Plus the creator is really nice and willing to help as well as listen to feedback. If you’re looking for a good study tool you’ve found it.
It’s great at first, but it’s a scam

I just got charged ~30 for the student yearly only for the puzzle tobe played every one hour in order to unlock. I hate this app because Of the confusing pricing. The limitations aren’t Clearly said
Developer Response
Thanks for the honest review, and I'm sorry the cost and the one-puzzle-per-hour limit on the free tier weren't clear before you subscribed. That's a communication gap on my end and I'm working on fixing it. If ScrollToll isn't the right fit, feel free to reach out through the support link on our App Store page, we'll get you set up with a refund right away. Thank you for giving it a try.

I have only used it for a brief time but I think this will really help any MCAT test takers who constantly scroll on apps! Even if it’s just a few questions a day, it’s still review and I am loving it!!
• Combine MCAT sections — Bio/Biochem, Chem/Phys and Psych/Soc now mix into one practice stream, so every unlock pulls across all three
• Combine TEAS Science + English the same way, and pick exactly which sections you want combined in Settings
• New Sound Effects and Haptics toggles — turn them on or off in Settings
• Sort and filter within a pack's question list
• Small fixes and polish
