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.

Verdict

The call

The clearest difference is update cadence: ScrollToll at every 4 days against AnkiLock's every 3 weeks. ScrollToll also leads on ratings volume (570 vs 13). AnkiLock's advantage is review sentiment (100% vs 76%) and rating (5.0 vs 4.8). On price, ads, in-app purchases and monetization model there is nothing between them.
