KeyDo - Learn. Earn. Unlock. Turn screen time into learning time. Every parent knows the daily standoff: reminders, negotiations, timers, and "just one more minute." KeyDo changes the pattern. Instead of simply limiting device use, KeyDo turns your child's favorite apps into something they earn by answering short, fun learning challenges first. Less arguing. More learning. Better habits. And they're not alone. Key the Fox, your child's clever, encouraging learning buddy, cheers them on at every step, turning study time into a quest instead of a chore. How It Works Learn Kids complete quick, age-appropriate challenges matched to their grade and subject, with read-aloud, tap, drag, and spell activities that feel like a game. Earn Every correct answer earns XP. Answer in a row to build a streak and earn even more, connecting effort directly to reward. Unlock When the learning goal is met, kids trade their XP to unlock real screen time on approved apps, safely powered by Apple Screen Time.

Ask the assistant about any lesson – it knows the notes made from your recordings, board photos and your class's shared notes, and finds the right lesson for you automatically. NOTES THAT REPLACE THE RECORDING Record a lesson (even with the screen off) or photograph the board and your notebook – the app turns it into a complete, organized note: definitions, explanations, examples, worked problems and homework. It's a lossless note, not a summary – it only skips filler and repetition, and it's meant to replace the recording itself. AN ASSISTANT THAT KNOWS YOUR LESSONS Ask "what did we do in the last physics lesson" or "what was covered on Thursday in math" – the assistant checks your calendar and finds the right lesson itself, no dates needed. It walks you through homework step by step instead of just handing you the answer, builds quiz questions from your notes before a test, and remembers your timetable. CALENDAR AND TIMETABLE Enter your timetable once, for the whole year – days, times and subjects. Every lesson in the week gets its own materials and its own note, day by day. Homework and tests remind you by themselves. Search finds a lesson by keyword, no scrolling through a notebook. CLASSES AND SHARING – KNOWLEDGE, NEVER FILES Join a class or start your own – you share knowledge, not files. No one in the class can see or download your recordings and photos, and it never shows who added what. You can also share a single subject with someone who has an account, or send a one-time link to a single lesson. PRIVACY No one sees the raw transcript or the text read from your photos – not even you. Only the finished lesson note is kept. Material marked private never reaches any class or shared note. We don't sell data, show ads or track you across other apps. The app is free to download, and an account starts on the free Standard plan. The interface is available in 18 languages. A ClassFlowy account is required (sign up in the app).

Verdict
The clearest difference is in-app purchases: ClassFlowy at none against Keydo App's 3. ClassFlowy also leads on update cadence (every 2 days vs every 4 months) and iOS requirement (15.0 vs 18.0). On price, ads and device support there is nothing between them.
