Another gift from Aprijal Pasaribu is the new Sting for Android. Sting is a Stockfish derivative forked from v2.3.1 a long time ago and maintained by Marek Kwiatkowski.
Sting is simply not a clone of the latest versions. That's why it resides in Rapidroid ranking and deserves attention for being in Top-10 with 3000+ ELO.
