The alternative chess GUI for Android, Chess Engines Play and Analysis (CEPA) got updated to 3.7 on June,30th.
I can't state CEPA is the best among other GUI's available. However, one thing is sure: It comes with the newest Stockfish development builds, dated June,26th.
The app can be downloaded via GOOGLE PLAY as usual.
Regarding the bundled engines, i will post Stockfish in a separate post, in case you are only interested in these but not the app.
