The short version

  • Each has a real cost: Melodics it requires MIDI-capable hardware to function at all, so it is not usable with an acoustic piano, an acoustic guitar or any instrument without a MIDI connection.; Stellarium it is desktop-only software, so it has no native touch-optimised phone interface; the similarly named mobile app is a different paid product from a different company.
  • They diverge on capability: Melodics covers MIDI-only input, Stellarium covers Photorealistic sky rendering.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Melodics

  • It requires MIDI-capable hardware to function at all, so it is not usable with an acoustic piano, an acoustic guitar or any instrument without a MIDI connection.
  • Its content is weighted toward electronic, hip-hop and contemporary genres, so a classical piano student will find the repertoire a poor fit compared with Flowkey.
  • It is not aimed at complete beginners deciding whether to learn an instrument, since it assumes you already own compatible gear and have basic familiarity with it.
  • Platform support is narrower than the microphone-based apps in this cluster, without the same breadth of mobile phone accessibility.
  • The precision it offers only matters if your MIDI hardware itself has good build quality and low latency; cheap or poorly calibrated controllers will still produce inconsistent scoring regardless of your playing.

Stellarium

  • It is desktop-only software, so it has no native touch-optimised phone interface; the similarly named mobile app is a different paid product from a different company.
  • As a volunteer-maintained open source project, support is community-based rather than a guaranteed commercial help desk.
  • The interface, while capable, is less immediately intuitive for a first-time user than a polished commercial phone app.
  • Telescope control and some advanced plugins require additional setup that a non-technical user may find fiddly.
  • Because it shares a name with the unrelated paid Stellarium Mobile Plus app, buyers researching pricing online can easily conflate the two products.

Answered from the vendors’ own pages

Melodics: Do I need special hardware for Melodics?

Yes, a MIDI keyboard, pad controller or electronic drum kit is required; there is no microphone-only mode.

Stellarium: Is Stellarium really free?

The desktop software is free and open source under the GPL licence. The separate mobile app, Stellarium Mobile Plus, is a different paid product.

Melodics: Does it teach classical piano?

Not really, its content leans toward electronic, hip-hop and contemporary genres rather than classical repertoire.

Stellarium: Is the mobile app made by the same team?

No. Stellarium Mobile Plus is built by Noctua Software, a different company, and is sold on subscription.

Melodics: How does it compare to Yousician or Flowkey on accuracy?

It is more precise because it reads exact MIDI data rather than inferring notes from audio, but only for users who own the required hardware.

Stellarium: What platforms does the free version run on?

Windows, macOS and Linux desktop.
