It's called Star Walk 2 https://play.google.com/store/apps/details?id=com.vitotechno... Just a FYI that if you choose to purchase the app you will still have to purchase the "all in one bundle" inside the app, I believe it's ~$5 and it gives you the sattelites, extended solar system, deep space objects and more. There's also a free ad supported version that offers the same base catalogue.
