- They diverge on capability: Melodics covers MIDI-only input, Sky Guide covers Light pollution forecasting.

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.
Sky Guide
- It is iOS-only, unlike SkySafari which also covers Android and desktop.
- It has moved from one-time purchase to a subscription model, and long-time users who paid once for earlier versions have criticised the change publicly.
- Pro tier pricing is high relative to Star Walk 2 for broadly similar core stargazing functionality.
- It has no telescope control, unlike SkySafari Plus and Pro, which limits it to naked-eye and camera-based observing.
- Its relationship to other apps under the same distribution platform is not clearly documented, which makes long-term support commitments harder to assess.

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.
Sky Guide: Is Sky Guide free?
The base app is free to download; Plus and Pro are subscription upgrades for a larger catalogue and forecasting features.
Melodics: Does it teach classical piano?
Not really, its content leans toward electronic, hip-hop and contemporary genres rather than classical repertoire.
Sky Guide: Did Sky Guide used to be a one-time purchase?
Yes, earlier versions were sold as a one-time purchase before it moved to the current free-plus-subscription model.
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.
Sky Guide: Does Sky Guide support telescope control?
No. For telescope control, SkySafari Plus or Pro is the better choice.
