Klaviero vs Simply Piano
Checked on 2026-08-06
Klaviero needs a MIDI keyboard and Chrome, Edge, Firefox or Opera on a desktop or laptop. It cannot run in Safari or on an iPhone or iPad, because Apple does not support Web MIDI. Simply Piano is a phone and tablet app and runs where Klaviero cannot. Full requirements.
Different device, different input, different goal
Simply Piano is a phone and tablet app. It listens through the microphone by default and supports MIDI as an accuracy upgrade. It is a structured course aimed at people starting from zero, and it is extremely good at getting a complete beginner to a first song.
Klaviero runs in a desktop browser, takes MIDI only for scoring, and gives you 315 classical charts with a rhythm-game score on top. It is not a beginner course.

Where Simply Piano wins
Absolute beginners. If you cannot find middle C, start there.
Portability. It is on your phone. Klaviero needs a computer and a cable.
Acoustic pianos. Microphone input means it works on a real piano with nothing plugged in.
Where Klaviero wins
Precision. Microphone detection has to guess at a chord. MIDI does not guess. When your score is the point, that difference is the point.
The classical library. 315 pieces, 811,562 notes, 27 composers, both hands charted separately, with the density of every piece published. The range runs from Satie's Gnossienne No. 3 at 2.7 notes per second to Liszt's Un Sospiro at 31.4.
The desktop. If you already sit at a keyboard next to a computer, a phone propped on the music desk is the worse setup and you know it.
Which to pick
Complete beginner with a phone and an acoustic piano: Simply Piano.
You own a MIDI keyboard, you can already play a bit, and you want a reason to practise for an hour: Klaviero.
