The developers of Acid APE Chess have released an OEX installer which comes with 2 engines Hakkapeliitta 3.0 and Stockfish 8.0. Following the first version of the app (that i may have skipped somehow), this is now v1.1 coming to add Senpai 1.0 into the package. This makes 3 alternative builds for us.
The builds are OEX compatible, so they will be automatically recognized by all compatible GUIs, like CfA and Droidfish.
The app is available for download at GOOGLE PLAY.
