Review. *2026-03-06* Good pictures to color, but still could be improved upon. Like more realistic pictures, better shading and brighter colors. But if they are constantly working on and improving, it will be great! ### 5/5 — Corrupted *2026-03-05* This app is corrupted! It only works half the time!! It is so annoying to deal with it. I love the pictures and would really like to use but until these many bugs are fixed I will not be using it anymore. After my last review I was contacted by the creators telling me they had made corrections and ask me to try again. I am very happy with the results!! The app seems to be working beautifully now! It’s my favorite paint-by-number app! **Developer response:** We hear you, and we’re sorry for the trouble!

More than once, I’ve been the victim of a bait and switch. Shame on you for trying to get business in such an underhanded way. **Developer response:** We sincerely apologize for the confusion!
