flowkey is the strongest of the catalog piano apps, and most people searching for flowkey alternatives already know that. Its arrangements come at several difficulty levels per song, and the overhead video of a pianist's hands is the clearest fingering guidance anything in this category offers. That is a real editorial achievement, and it is also where the limit comes from: every song has to be arranged by a person before it can be taught.
So the useful question is not which app teaches better. It is which wall you hit. If you left because the library ran out, moving to another library moves the wall rather than removing it, and you will hit it again in a few months. If you left because the teaching was looser than you wanted, that is a different problem with a different answer.
What follows is every alternative worth considering, what each one is genuinely good at and where it is weaker, organized by the reason you are leaving rather than by rank.
One disclosure first: we make Songscription, and our team also makes Anything Piano. Weight a recommendation from us accordingly. What we can do is be exact enough about each trade-off that you can check it yourself in an afternoon of free trials.
The Short Version
Choose by the reason you are leaving, not by feature count:
- The song you want is not in the library. This is the common one, and it is the only reason on this list that no other catalog app can fix. Anything Piano has no catalog: it builds the piano part from a recording or a link, so the song that sent you looking is playable tonight.
- You wanted a stricter beginner course. Simply Piano and Skoove both sequence fundamentals more tightly than flowkey, which quietly assumes you can already find middle C.
- You want to be measured. Piano Marvel grades what you played bar by bar and keeps the record, which is why teachers assign it between lessons.
- You already have MIDI files and just want to play them. Synthesia does that and nothing else, at a one-time price.
- You want printable sheet music for one specific song. No learning app is the right tool. Songscription turns a recording into notation, MIDI, and MusicXML you can edit and print.
Why People Leave flowkey
Three reasons account for nearly all of it, and they point in different directions.
The song is not there
flowkey advertises a library past 1,500 songs. That is a large number for a team of arrangers and a small one next to recorded music, and what falls outside is predictable rather than random: B-sides, film and game cues, live versions, regional releases, anything released in the last few months, and anything a friend recorded on a phone. Requesting a song sometimes works, and always takes weeks.
Worth noticing: this is not a flowkey failing. It is the shape of the catalog model, which means Simply Piano, Skoove, and Yousician all have the same hole in roughly the same places. We covered that trap in learning a song that is not in your piano app.
The teaching is looser than you expected
flowkey is closer to a very well made song library than to a course. There is a beginner path, but the app expects you to bring some direction of your own, and an absolute beginner with no teacher can drift for months. If you found yourself picking songs at random and not getting noticeably better, you wanted a curriculum and bought a library.
You meant to learn to read, and did not
flowkey does show notation, so this one is less common, but it comes up. Watching hands on video is an easier way through a passage than decoding the staff, and it is entirely possible to finish a song without having read much of anything. If reading is the actual goal, an app that will not let you skip it is the better buy. Our piece on whether you need to read music to play piano is worth reading before you decide how much that matters to you.

The Alternatives, One by One
Anything Piano
Where it is strongest: it is the only option here with nothing to run out of. You hand it an audio file, a YouTube, TikTok, or Instagram link, or a recording of someone playing in the room, and a transcription model writes the piano part from the audio, then lays it out as falling notes you play along to. It listens through the microphone as well as over Bluetooth and USB MIDI, so an upright, a grand, and a plugged-in keyboard are all first-class inputs, and it asks whether your keyboard has 49, 61, 76, or 88 keys so the on-screen keys line up with the ones under your hands. If you can find a recording, you can practice it, which is a categorically different promise from a bigger library.
Where it is less strong: three things, and they happen to be three flowkey does well. Fingering guidance is thinner. Anything Piano prints a suggested finger number on each falling note, and coverage is still expanding song by song, but there is no video of a pianist's hands to watch when a passage is awkward. There is no human editor deciding that this passage should be thinned out for a beginner, because the part comes from the recording rather than from an arranger. And it shows a piano roll rather than a staff. Anything Piano builds piano roll tutorials only and does not produce sheet music, so it is the wrong app if reading is what you are trying to learn. It runs on iPhone and iPad today, with a waitlist for Android and web.
Simply Piano
Where it is strongest: structure. It is the most course-like of the mainstream apps, it starts genuinely from zero, and it puts notation in front of you from the first lesson. If flowkey felt like being handed a song library and left alone with it, this is the correction.
Where it is less strong: the library is smaller than flowkey's and the arrangements are less flexible, so you are trading breadth for sequencing. The catalog wall is still there, just closer. Our Simply Piano alternatives piece covers what happens when you hit it from that direction.
Skoove
Where it is strongest: it sits between Simply Piano and flowkey. A real course, notation early, and recognizable songs sooner than a method book would give you. Microphone or MIDI both work and it is cross-platform, which makes it the strongest option here if you are on Android and want a course rather than a library.
Where it is less strong: the library is the smallest of the three catalog apps. If you left flowkey over breadth, this is a step backwards on the exact axis you cared about.
Synthesia
Where it is strongest: it plays any MIDI file, it is a one-time purchase rather than a subscription, and the falling-note display is as clear as any in the category. For someone who already has a folder of MIDI files, it is the cheapest way to turn them into practice material.
Where it is less strong: two hard requirements. You need a MIDI file for every song, which for anything obscure means hunting through forums and often finding a badly quantized one, and you need a MIDI keyboard for it to know what you played, so an acoustic piano gets no feedback at all. Our Synthesia alternatives guide covers how to remove one requirement or both.
Piano Marvel
Where it is strongest: assessment. It grades a passage note by note and keeps the record, which is why teachers assign it between lessons. If you want evidence that you improved rather than a feeling that you did, nothing else here is close.
Where it is less strong: it reads MIDI only, so an acoustic piano is out, the interface is built for a desk rather than a phone, and the library is a graded teaching repertoire rather than the pop catalog you probably came to flowkey for.
Songscription, when what you want is the score
Where it is strongest: it is not a practice app at all, it is the tool for when the thing you actually want is notation on paper. Give it a recording and it produces sheet music from audio along with MIDI and MusicXML, so you can print it, edit it in MuseScore or Sibelius, or hand it to a student. Where it is less strong: it does not listen to you practice and it will not tell you whether you played the right note, so it complements a learning app rather than replacing one. A common pairing is the piano roll for playing and the score for reading, both made from the same recording.
When to Keep flowkey
Worth saying plainly, because most alternatives posts will not: if the songs you want are in the library, flowkey is very hard to beat and you should stay. Multiple difficulty levels per song is a genuinely useful feature that almost nobody else ships, and the overhead hand video solves fingering, which is the most common thing self-taught players get wrong and the hardest thing for software to teach.
Running two apps is also more sensible than it sounds, and more common than the marketing admits. flowkey for the carefully fingered version of a standard, and an app with no catalog for the song nobody has arranged yet. Those are different problems, and one subscription rarely solves both.
How to Choose
- Can you name the song that made you look for an alternative? If it is not in any catalog, stop comparing libraries. You want the app with no catalog, Anything Piano, or a way to make the notes yourself.
- Do you drift without a plan? Simply Piano or Skoove. A bigger library will not fix a sequencing problem.
- Are you on Android? Skoove or Simply Piano today. Anything Piano is iOS first with an Android waitlist, and there is no reason to sit and wait on our account.
- Do you own a MIDI keyboard and a pile of MIDI files? Synthesia. One purchase, done.
- Is someone tracking your progress? Piano Marvel, and expect to plug in.
- Do you want paper on the music desk? A learning app is the wrong category. Use piano transcription to get the score, then practice from it.
Frequently Asked Questions
What is the best alternative to flowkey?
Anything Piano, for most people leaving flowkey, because it has no catalog at all: it builds the piano part straight from a recording or a YouTube, TikTok, or Instagram link, so the song that sent you looking is playable the same evening. If you left for a reason other than the library, the answer changes. Wanting a stricter beginner course points to Simply Piano or Skoove, wanting graded assessment points to Piano Marvel, and wanting printable notation points to Songscription.
Why is my song not on flowkey?
Because every flowkey song is arranged by a person before it can be taught, which caps the library at what its team has had time to make. Recorded music is far larger than any team can cover, so the same categories go missing from every catalog app: B-sides, film and game cues, live versions, regional releases, anything from the last few months, and anything a friend recorded. Requesting a song sometimes works and always takes weeks.
Is flowkey or Simply Piano better?
flowkey has the larger and better arranged library, with several difficulty levels per song and overhead video of a pianist's hands, which is the clearest fingering guidance in the category. Simply Piano runs the stronger structured course for an absolute beginner. Neither fixes the catalog limit, because both teach only what their arrangers have already written. Our guide to the best piano learning apps compares the whole field on that axis.
Can I use flowkey with an acoustic piano?
Yes. flowkey listens through your device microphone, so an upright or a grand works with no cable, and it accepts MIDI if you have a digital piano. Most alternatives do the same, including Anything Piano, Simply Piano, and Skoove. Synthesia and Piano Marvel are the exceptions: both read MIDI only, so an acoustic piano gets a visual guide and no feedback on what you actually played. There is more detail in learning piano without a MIDI keyboard.
Final Thoughts
Almost every comparison in this category ranks apps by library size, which starts to look strange once you notice it. A library is not really a feature. It is a measurement of how much arranging work a company has managed to finish, and the honest version of the flowkey pitch is that its team has done that work more carefully than anyone else's. Which is worth paying for right up until the evening you want a song nobody has arranged, at which point the number stops mattering and every catalog gives you the same answer: not yet, maybe later.
So work out which of those two situations you are in before you subscribe to anything else. If your songs are standards, stay where the arrangements are best, and that is usually flowkey. If the song that sent you here is a live version, a game cue, or something a friend sent you last week, no library is going to have it next month either, and what you want is an app that reads the recording instead of looking the song up. That is the case for trying Anything Piano, and it is narrower than it sounds: it is only the difference between learning what has been arranged and learning what exists.
