Knojo

Everything you learn starts fading the moment you close the book. Knojo brings each idea back the moment before it slips — so what you study actually sticks. Knojo is a spaced-repetition flashcard app built for calm, consistent learning. Turn your notes, articles, and study material into smart flashcards, tie them to real goals like "React interview prep," "Dutch vocabulary," or "Biology exam," and let Knojo handle the rest. Every day it surfaces only the cards that are due — usually a focused five-minute review — and schedules the next one based on how well you remembered. What you can do with Knojo: • Spaced repetition that works — rate each card Forgot, Hard, Good, or Easy and Knojo schedules the perfect next review. • AI-generated flashcards — paste your notes or an article and get clean, study-ready cards in seconds. • Learning goals — organize cards around what you're actually working toward. • Daily review queue — see only what's due today, with no endless decks and no overwhelm. • Quiz mode — test recall with AI-powered quizzes. • Streaks & achievements — build a memory habit you'll keep. • One gentle daily reminder — show up for a few focused minutes, then get on with your day. • Your memory coach — guidance that keeps you consistent. Knojo is a dojo for your memory — disciplined, quiet, and designed to fight overwhelm instead of adding to it. Whether you're preparing for an exam, learning a language, prepping for interviews, or just refusing to forget the books you read, Knojo protects what you learn before it fades. Free to start. Upgrade to Pro for unlimited AI cards and quizzes. Download Knojo and start remembering what matters. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Verdict
The clearest difference is update cadence: Knojo at every 5 days against Frontend Masters's every 3 weeks. Frontend Masters's advantage is iOS requirement (11.0 vs 15.1). On price, ads, in-app purchases and device support there is nothing between them.
