My favourtie drawing app. BUT after the lastest update I cannot focus on my work. It's not a good choice to have ads pop up EVERY time the save button is used. It wastes time not to mention that it causes the app to crash before saving sometimes. It would be better if users could watch ads to use premium perks for a limited time. Perks like tone curve are too important to be locked behind a paywall. I'm a bit disappointed.(Also please, add symmetry tool. Tool not brush.)
