Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Busuu
- The free tier is limited enough that meaningful progress in most languages effectively requires the Premium subscription within a few weeks of use.
- Community correction quality depends on other users being active in your target language at the time you submit, so response speed and quality vary noticeably by language and time zone.
- Since the 2022 Chegg acquisition, Busuu sits inside a company built around subscription homework and study services, and Chegg has faced its own commercial pressure from AI tools reducing demand for its core products, which is a relevant roadmap risk.
- Course depth and language coverage are uneven; widely spoken languages such as Spanish and French have far more content than smaller language courses.
- The official Busuu certificate is not a recognised external qualification equivalent to something like an IELTS or DELF exam, so it carries limited weight outside informal 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.
