Nothing sounds better than another 3000+ ELO engine made available for Android. Please welcome Chiron and my thanks to Alex for the notification.
These are the good news. The bad news on the other side is that the engine is NOT FREE. It must be purchased via GOOGLE PLAY and just like Komodo, a licence check is necessary for getting it running under Chess for Android, Chessbase or Droidfish...
Now should we scream in agony with empty pockets? Nooo... Chiron for Android is absolutely not expensive: 3 EUR vs approx 30 EUR for the PC version is not significant.
If i call the above a bad news, there's nothing related to the cost. Actually if i'm not too comfortable with paid engines, that's because of the downloads via Google Play and online checking for every device i'm using for chess. It's not possible to duplicate it offline even after purchasing it for a device.
But we cares about installation ergonomics? I'm happy i can introduce another strong engine in Rapidroid, probably in June-2016 ranking.
