The new Chiron 4 is about 70 points stronger than Chiron 3, according to the author Ubaldo Andrea Farina. Although it's an update to the engine, the Android app is a different one and will keep Chiron 3 alive on the same device. Interested users can even make two versions play each other the same way as it's possible between Komodo versions.
Chiron 4 costs 2.5 EUR only and the licence checking works exactly like Komodo via Google Play.
WHAT'S NEW (10-Jan-17):

I made first test between Chiron 3 and 4, Lenovo TAB 1GB RAM, 4 cores, 64mb hash, 100 games, book-Rybka.bin, time 2min+1sec.
Score - Chiron 3 (39)-Chiron 4 (61), it's a good start!!
Yes indeed. I still need time to publish a Rapidroid update. However, first rounds leave no doubt about Chiron 4 in 3rd place behind Stockfish and Komodo. It performed better than the oldie Critter arm5. Something that took too long to happen...
