Awesome, I'll definitely try it.

I've been paying for Piano Marvel for a few years, and there is tons of room for improvement in this space:

- Native, non-janky app. Ideally cross-platform.

- More inspiring music in lessons.

- Recommendation algorithm for what piece/lesson to practice next.

- More methods of measuring progress over time.

- Spaced repetition for sight reading, technique, scales, ear training, sections of known pieces.

- Splitting pieces automatically into overlapping sections to practice, RH, LH and hands together (whatever makes sense).

- Simple streaming/recording features for use with piano lessons over video chat (screen/video/audio mixed together to a single stream?).

- Show music theory concepts based on what you are playing, in the context of the current piece. E.g. what chord is being played, and its function. Possible continuations.

My setup is a Macbook + FP-30 + USB midi cable. Having the laptop standing on top of the piano makes keyboard and touch pad usage clunky, so navigation must be simple. Also uploading custom scores is a must for me.

It doesn't have most of what you say, but it does let you practice on custom scores (midi files), so maybe it can be part of the solution:
