I bought loopstation (https://play.google.com/store/apps/details?id=com.zuidsoft.loopstation2) as a tool for songwriting.
I don't know that I'd want to use it for live performance (or any android app for that matter) -- but for laying down melodic ideas quickly and playing over the top, it's super handy.
If you want to do live stuff -- I'd seriously look at investing in a boss loopstation or a digitech jamman. Easily controllable by your feet, and are widely used.
Sadly no there are some equivalents but there not as nice I use loop station

You could try any of the looper applications in the google play store.
