Came across this endgame tablebase app for free on google play for android tablets. Excellent piece of endgame software. They've added features where you can play the endgame and know whether you made the correct move or not.
Similar to the Naimalov 6 piece now with 100% accuracy you can check out 7 piece endings. Excellent software and free.
