Pros: my toddler loves this coloring app and has been playing this since 18 months, and I believe it has taught her to start coloring within the lines. Really easy for her to navigate and lots of coloring tools and pictures to choose from. First 10 coloring pages or so are free with a couple free tools. The packs aren't ridiculously expensive either. Cons: It occasionally glitches when you color a section, and it will simultaneously erase another section that you previously colored. A little annoying, and it does bother my toddler a bit too. I feel like if I'm putting money into an app, I would like them to use their profits towards repairing this glitch. Also, the app has randomly started running on it's own while my tablet is off too... Not sure if that's an app issue or a device issue though. Overall, I recommend this app among other BimiBoo apps. My 22 month old loves BimiBoo, and I am still willing to keep investing money in these apps provided they continue to provide me with quality gameplay.

Jan 2021- If you have a tablet with multiple users the app constantly wakes up in the background and plays the music no matter what user profile you are on. Used on a Tab S7. Even Samsung's device care states issues with the app waking up to frequently. Giving two stars only because my kids like it. Once the wakeup issue is fixed will rereview. Update May 2021: Still not fixed. Plays music in the background on Tab S7 profiles... will do this on multiple profiles for each kid. Will hear this song playing in the middle of the night if we don't force close the app or shut down the tablets. No other app does this... which is very annoying. Removing another star... will do 4 to 5 starts if resolved.. otherwise support of the app is lacking.
