What's the best Android app for learning piano with a realistic keyboard interface?

Real Piano For Pianists is an Android application that provides a detailed piano simulation tailored for users seeking to learn or refine their piano skills. It features a full 88-key keyboard with multi-touch support and velocity-sensitive response, allowing players to experience dynamic sound changes based on touch pressure, much like an acoustic piano. This makes it suitable for practicing scales, chords, and songs in real-world scenarios, such as during commutes or in small living spaces. The app includes a built-in metronome for timing exercises and recording functionality to track progress over time. Users can switch between different instrument sounds, which aids in exploring musical styles and composition. Reviews indicate that many find the interface intuitive and the sound quality impressive for a mobile app. However, some users report occasional latency on older Android devices, and the free version includes advertisements that can interrupt focused practice sessions. Despite these limitations, it serves as a reliable tool for daily practice, though it shouldn't replace formal lessons or high-end equipment for advanced training.
