The app is a augmented reality (AR) professional piano with 61 keys or 88 keys. You can place every plane a real and fine-tuned ar piano called Play Mode.
Additionally, the app can recognize audio or voice and transfer this to piano self-playing called Listen Mode which is specially interesting.
You can record your screen to share your Solo in Play Mode or your Play with Accompaniments by Listen Mode.
More features are on the roadmap.
