Your app keeps freezing up – Pixel Artist: Color Number Review

I like the pixel artist app, except for one thing. Every time I have colored several of the pictures, it ends up freezing up and I have to end up deleting it and starting over. I don’t want to pay for the yearly cost and have it keep freezing up. I don’t see a place to contact anyone to figure out why it keeps freezing up, so I may just have to go with another app.....
