What's a good Android game that might help with relaxation and focus through music?

I sometimes suggest "Piano" to clients who are looking for ways to incorporate more mindful activities into their day. It’s not just a game; it's a way to engage with music in an active way. The thoughtful design choices, like the gentle feedback and increasing levels of challenge, encourage healthy usage patterns rather than addictive gameplay. Plus, it's a nice alternative to social media scrolling when I need a little mental break. It doesn't sell your data to Facebook, which is a huge plus for me. I find it's perfect for an evening wind-down to help track patterns without being invasive and prepare for sleep.
