Thank you ### 2/5 — App not working properly *2024-03-11* For some reason this app keeps on going back to Home Screen. when browsing through/scrolling down through the diffrent options of pictures to colour In please fix this issue as it is a frustrating and annoying inconvenience. ### 5/5 — AMAZING!!!!!!!!! *2023-03-28* I LOVE IT!!!!!!!!!!!!!!! ### 5/5 — Having fun relaxing *2023-01-31* I love coloring to relax it’s been the best thing I’ve ever done, I have a lot of coloring books that I do so I have a variety. That way I don’t get bored with just one. I am glad they came out with this idea!!!!! Angel Enjoy Relaxing ### 1/5 — Quits saved pictures *2022-10-26* I like this app and paid for the upgrade but I have the issues that others have noted here. I can’t resume a saved picture. Please fix!! ### 1/5 — Keeps crashing *2022-03-17* Every time I go to finish a picture it crashes. They won’t pull up so I can finish. Please check into this issue since I just upgraded & would like to finish the ones I’ve started. Thank you. March 17, 2022 This still hasn’t been fixed. I have even deleted the app & reinstalled thinking that may help. And of course I lost all everything. I have started over again & still unable to go in to finish the ones I couldn’t complete in one sitting. Please please fix this! ### 3/5 — Cannot finish saved pictures *2022-03-14* I like this app BUT if I cannot complete on one sitting I cannot got back and complete. Every time I hit continue it shuts the app down. Ver discouraging, especially on a daily picture, to have to start over when over half completed on a detailed one. Fix this bug! ### 1/5 — Wonder colour Colour by no *2021-10-11* I just paid £10.00 for this and cannot resume my picture that I started, I don’t think much of this app if it keeps doing this Lynn ### 1/5 — Won’t open picture to finish coloring *2021-07-12* Used to love this app but it won’t let me open the pictures now to let me finish them. It just spins. Please fix or I’ll have to delete it!!! ### 3/5 — Messed up *2021-06-15* Downloaded this app few days ago and every time I go back in to complete a picture it keeps kicking me out. I have 3 unfinished pictures but I can’t complete any of them. Would give this 5 stars but for that problem, will have to delete if that continues. Revising my review, I now give this game a 2 star (at best) I now have 5 puzzles all unfinished and no way of finishing them, was able to work on one 3-4 days after I started it. There is a my Art category with an arrow that says continue but click on that and get ( wait a while) message and then kicks me out. I guess wait a while means forever, not worth the hassle don’t think the developers know what they are doing. Really bad App. ## Frequently asked questions about Wonder Color ### What is Wonder Color - Color by Number?
