This was a pretty good app, but the ads have made it almost unusable. The program crashes frequently so you're encouraged to save a lot, only to get sometime UNSKIPABLE ads when you save. You also get ads when trying to go to another canvas and sometimes the ads force you to go to the app store because their close button doesn't work. It's honestly both insane and depressing how awful this has made the app and I cannot recommend it to anyone anymore.
