Where each one falls short

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

Flowkey

  • Microphone-only users, without a MIDI keyboard, still hit the same accuracy limits as Simply Piano on fast or dense passages.
  • Its curriculum is less structured around fundamentals than Simply Piano for a complete beginner with no prior reading ability.
  • It is piano only, so a household wanting to cover guitar or other instruments needs a separate subscription elsewhere.
  • The song licensing model means catalogue availability can shift over time as licences change, occasionally removing a previously available arrangement.
  • Full benefit of its more precise feedback mode requires owning a MIDI-capable keyboard, which is an additional cost beyond the subscription for anyone with only an acoustic piano.

Open edX

  • No license fees for software but requires separate spending on hosting, infrastructure, and maintenance
  • Customization and support from third-party providers requires additional investment
