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. ### 3/5 — Moves to much *2021-03-31* I would like the coloring app but it does move to much when you color, to jumpy. Hope this problem does get fixed. Would like to try it down the road. ### 4/5 — 4 Stars *2020-03-29* Very relaxing but with a lot of ads. Need to strain your vision and is helpful after a long day. Music is calming and welcoming. Makes me feel safe. ### 4/5 — Great *2020-03-19* Just started the app and it’s fun to do. Like the way it tells you how many colors ### 5/5 — Wonder coolor *2020-01-18, version 1.4* It is one of my favorites ### 4/5 — Needs work *2019-10-06* Although it’s a good coloring app, it would need a little more work to be awesome!!!🤗 **Developer response:** Thank you for playing Wonder Color. We are hard working to improve the game. ## Most critical reviews (10 lowest-rated) ### 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! ### 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!!! ### 1/5 — WONDER COLOR *2020-06-18, version 1.5.3* I accidentally hit one star. I have contacted you in the past. When there are places to cover the number to use is NOT SHOWING. IF I COULD DO THE ENTIRE PICTURE I WOULD GIVE YOU A MILLION STARS. I WOULD PAY FOR PREMIUM. HOPE YOU GRT THIS FIXED. ### 1/5 — Wish I liked this app :-/ *2020-06-17* I gave this app one star because it made me nauseated every time I touched the picture it move, WAY too much!! And wow the ads are ridiculous!!! Every 5 seconds an ad popped up on the screen. I get it we have to pay to remove ads but geesh that’s a bit much. I migh try this app another time when the glitches are fixed. Bye for now 🙋🏻‍♀️ **Developer response:** Thank you for your feedback. We will check soon ### 2/5 — Glitches *2026-03-20* Can you please fix the game because it keeps crashing and glitching. 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. ### 2/5 — Lines to thick and black *2020-10-19* I like lots of the pictures but the lines are too harsh, black and thick. In some spots the color doesn’t even show up and there are too many small blank white spots that make it difficult to find spots that need color. ### 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! ## Most praised reviews (10 highest-rated) ### 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.

I also like the music in the background. ### 5/5 — Love it! *2020-06-03* I normally don’t purchase and I can’t remember the last time I gave 5 stars. Enjoy this so much that I spent the one time fee.
