I think if you're looking for a reasonable coloring book application that this one and the first version of Tayasui Color are the only apps worth considering. All other coloring programs are insane with their subscription pricing. I just refuse to pay forever to color, that's ridiculous in my opinion and a huge waste of money.
The Tayasui apps are great, though, I think and offer a lot of quality features. You have lots of different pages to choose from and great art tools as well I believe.
The only function that keeps me from giving this app five stars is the community feature. Any social sharing options in this developer's programs never seem to work properly as far as I'm concerned. In this one in the community section you're able to always see the "Featured" section quite well I think. But, if you choose the "Popular" or "Last Posted" sections you just get no results no matter how long you sit there waiting for it load I've found. Which is quite frustrating and the reason I don't give this otherwise great program five stars as I've said. Yet, if the sharing function isn't important to you I could easily see others viewing this app as perfect.
Many thanks to the developer, Tayasui, for another great art application. I will always look forward to any applications that this developer releases. Thanks, again, for this program and God bless.
