In beta, on Android
Music that stays.
Ritmemo teaches music, with the piano as the way in. Short lessons, songs you play from memory, and a way to plug in your own AI, so it can see how you really played and plan your practice.
Built so the music stays with you
Most apps teach you which key to press next. Ritmemo teaches you to understand what you hear and play, and to keep it.
- Remember first
- Every lesson opens with an earlier piece, played from memory before any notes appear. Trying to remember is what makes a song last.
- You judge first
- After a recording you rate it from 1 to 5, then see what the measurement says. Learning to hear yourself is part of learning music.
- Songs come back
- Older pieces return at growing gaps, so nothing quietly disappears after a break.
- Help that fades
- Note letters, lit keys and sheet music that follows you go away over time. The goal is to play with no app at all.
- Music, not only keys
- Pulse, rhythm, melody, harmony, keys, form and expression. One idea per lesson, heard before it's named.
- Honest numbers
- No points, hearts or confetti. It tells you what really happened, including when progress is flat.
A lesson in about 30 minutes
Every lesson has the same six parts, in the same order. You're playing, listening or answering most of the time.
Repetition 5 min
Play something from an earlier lesson from memory, before you see it.
Theory 5 min
One music idea, heard in real music first and named after.
Practice 7 min
Work on the new skill in small sections, at your own pace.
Challenge 5 min
The app shows the next notes and waits for you. Then try to beat your own clean time.
Music 5 min
Use the skill in a real piece, and make some choices of your own.
Test 5 min
One study habit, a task for your paper notebook, and a few questions about the idea.
A lesson often takes several sittings, and that's normal. Each one says when you're ready to move on. After the lesson, Practice brings back what you've learned in rounds of six questions, at gaps of 1, 2, 4, 8 and 16 days.
How it works
You can start with nothing but the app and an instrument. Each step after that adds something.
Follow the course
Music + Piano goes from beginner to advanced, in English and Brazilian Portuguese. Nothing is locked: the order is a suggestion, and the app marks where to continue.
Connect your piano (optional)
With a USB MIDI keyboard, the app records your playing, lights up the sheet music as you go, and its challenges listen to you. The server does the scoring, so the numbers are the same every time.
Plug in your own AI (optional)
Ritmemo doesn't come with an AI. If you use Claude, or any AI that supports MCP, you can connect it to your account with its own token. It can then read your recordings and answers, and write a private daily plan that appears above the course.
It started as an experiment
One adult student learns piano for six months with an AI as their only teacher, and writes a paper about it. The study measures what lasts: songs played from memory after a week away, reading new music, transposing, playing by ear, and expression.
It's a single-case study with no control group, so it can show what happened, not that the AI caused it. The AI teacher logs its own mistakes, and the paper will say where AI teaching helped and where it failed.

Ritmemo is in beta
It works, and it's in daily use for the experiment. It's also early, and here's what that means.
- Android only. The app installs from an APK file, with no store listing yet.
- English and Brazilian Portuguese. The app and every lesson come in both.
- Lessons are still being revised. The course has 62 lessons in three modules. Every version of a lesson is kept, with the reason it changed.
- Things will change. Screens and lessons move as we learn. Your progress lives on the server, so a new phone gets it all back.
- Online only. The app needs an internet connection. Work done during a short drop is sent when it comes back.
- Your data. Your plans and playing are private from other students. Whoever runs the server can technically read its data, as with most apps.
Questions
Do I need a piano?
You need a piano or keyboard to play on. Connecting it to your phone is optional. With a USB MIDI connection, the app records your playing, lights up the sheet music as you go, and its challenges listen to you.
Do I need to read music?
No. At first a letter under each note tells you which key to play, and the lessons teach reading a little at a time, until the letters go away.
Does Ritmemo include an AI?
No. The whole course works on its own, with no AI. If you already use Claude or another AI that supports MCP, you can connect it to your account, and it can plan your practice from how you really played.
Is it a game?
No. There are no points, hearts or confetti. The streak counts only days with real practice, and the daily goal is your own number of minutes.
Is there an iPhone version?
Not yet. The beta is Android only.
What music will I play?
Original exercises and public-domain pieces, in many styles. Songs under copyright are taught from their chords and short patterns, with sheet music you get yourself.
Can the app see my hands?
No. It knows which notes you played, when, and how hard. It can't see your posture, hands or fingering, so watch those yourself. If playing hurts, stop and see a professional.
