I have come across a nice training App from Nic Barrow. It is in the apple app store (not sure about android, i don't have a android device) and is free with in app purchases. I feel that there are drills in here that can benefit both players although being made for snooker players. It called PracticeGuru, it's the only app of it's kind so it's the only one to show up
Just thought i'd share (maybe some can check and post if it's on android)
