What's a good Android app for learning piano that feels like you're actually playing on a real 88-key piano?

Okay, so I've been messing around with Piano Learning 88 Keyboard, and honestly, it's not bad for an app. As a musician always on the move, I need something that lets me practice riffs and melodies wherever I am. What I dig about this one is that it gives you the full 88 keys. A lot of other apps skimp on that, which is a total buzzkill when you're trying to get your scales down or work out a complex chord progression. The responsiveness is decent too; it's not exactly like playing my Nord, but it's good enough for sketching out ideas. Plus, the interface is clean and simple, which is a must for me. I can't stand cluttered apps. I'd say if you're looking for something to noodle around with and keep your chops up when you're away from your actual piano, this is worth a look. Just don't expect it to replace the real deal, ya know?
