Lock Instagram & TikTok behind your OWN notes. Snap them, we turn them into questions - answer one to scroll. Every unlock is a rep for your next exam.
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.

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 :)
honestly changed my life

i am an avid doomscroller and also a pre-PA student with adhd. this app genuinely has been the best decision ive made this year. it feels so rewarding to get an MCAT question right (even tho im personally not going to take the MCAT) and reduce my instagram usage at the same time. i highly recommend for students or anyone wishing to decrease their time on social media. i love the pause option for nights im not doing work or during my lunch break! please never get rid of the free version. if i had more money id pay for the pro version because thats how much this app genuinely benefits me. it will change your life! do it!
Good App with One Downside
ThatRandomTrash
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.
This way of learning is it!

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.
Your notes just got more room.
• DROP IN A WHOLE TEXTBOOK — pick a big PDF and choose exactly which part to use. Tap any page to read it full-size before you decide.
• PASTE AS MUCH AS YOU WANT — up to ~125 pages at once. We'll find the most testable parts and build your pack from those.
• KNOW WHAT'S IN YOUR PACK — a live page meter while you paste, and a receipt showing exactly which pages your pack was built from.
• NO MORE MYSTERY WAITS — while your questions are written, you'll see what's happening step by step. If your upload can't become questions, we tell you why and let you try different material.
• PACKS FINISH THEMSELVES — if you finish setup before we finish writing, the rest of your questions now arrive on their own.
• PACK CLEARED — a little celebration when you've seen every card in a pack, and a one-tap way to build your next one.
• START FRESH — swipe any pack to reset its progress.
• NIGHT-FRIENDLY — a new Appearance setting lets the answer and upload sheets go dark with your phone.
