Stop scrolling before you study. Start scrolling because you studied. FlashScroll turns your flashcard study sessions into real, spendable time on the apps you actually want to use — Instagram, TikTok, whatever you choose. No willpower required, no guilt trips. Just a simple trade: study first, scroll after. HOW IT WORKS • Create flashcards — organize them into folders by subject, class, or however you think • Review with spaced repetition — our scheduling algorithm shows you cards right before you'd forget them, so studying actually sticks • Earn scroll time — every card you review correctly banks real minutes • Choose your apps — pick which apps on your phone stay locked until you've earned time to use them, using Apple's own Screen Time technology • Unlock and scroll, guilt-free — spend your earned minutes exactly how you want BUILT FOR HOW STUDENTS ACTUALLY STUDY • Smart spaced repetition (SM-2 algorithm) — the same proven method behind Anki and other serious study tools • Study streaks — build a habit, don't just cram • Progress tracking — see what's working and where you're falling behind • Study Timer — bank scroll time for focused study sessions, not just flashcard reviews AI-POWERED FLASHCARD CREATION (Pro) Upload your notes or a PDF and let AI turn them into a ready-to-study deck in seconds. No more spending an hour making cards before you can spend five minutes studying them. MULTIMEDIA FLASHCARDS (Pro) Attach photos to your cards — diagrams, handwritten notes, anything a picture explains better than text. YOUR SCREEN TIME, YOUR RULES FlashScroll uses Apple's Screen Time API to enforce the deal you make with yourself. You choose exactly which apps to restrict — nothing is selected for you, and we never see which apps you picked. It's a tool to build a habit, not a surveillance system. FREE TO START Create up to 3 decks and 150 flashcards, review with full spaced repetition, and earn scroll time — completely free, no trial required. Upgrade to Pro anytime for unlimited decks and cards, unlimited AI-generated flashcards, multimedia cards, a faster scroll-time earn rate, and more. Terms of Use: https://dfelipe2613.github.io/Flash-look-/terms-of-use.html Privacy Policy: https://dfelipe2613.github.io/Flash-look-/privacy-policy.html Study first. Scroll later. FlashScroll.

Verdict
The clearest difference is ads: FlashScroll at none against DuoCards's shown. FlashScroll also leads on update cadence (every 2 weeks vs monthly). DuoCards's advantage is device support (3 vs 1) and iOS requirement (13.0 vs 17.0). On price and in-app purchases there is nothing between them.
