I'm looking for a fairly simple app to help me with my gesture drawing sessions. I've tried searching for myself but haven't had any luck. Features I'm looking for: Android compatible One time purchase and no ads. I want to pay for the product, not be the product. Use local photos. I'm bringing my own photo sets. Ability to adjust the time per image and the total time/number of pictures in a session Works while the device is 100% offline Keeps the screen awake Nice to haves: Timed breaks A no repeats mode. It'll only select new pictures from the photo set when possible. Carries across from session to session
