Create a Coloring MasterpieceColorBook is rated at 5.0 stars in Google Play. It is rated at 3.4 stars in the Amazon Appstore.
ColorBook is a photo-editing app for your Android device that lets you turn your own personal pictures into coloring book images. Create colored masterpieces and share them with your family and friends; each image you create will be truly one of a kind.
Select Your Palette
It's easy to turn a photo into a customized coloring book image. Just open the ColorBook app and take a photo (or choose one from your personal photo gallery or Facebook profile). The photo will appear on your screen transformed into a black and white, pencil-drawn image.
If you like, you can change the visual style of the image before you go any further. Touch the Menu button, then select Style, and you'll find three options: ColorBook (the default line-drawing style), GrayScale, and Original. Pick your favorite. Now it's time to get coloring!
Stay Inside the Lines--or Don't
Start by choosing a brush size and paint color from the tabs at the bottom of the screen. Create broad strokes with a large brush, or pick one that's pinpoint-sized to get precise. For detail work, you can use the app's two-finger zoom feature to see up close and make sure you color inside the lines.
The color choices are wide open, so be creative. Basic options are available at a single touch, but you can also bring up a color wheel and choose the exact shade you want.
Coloring is easy. Using your finger, touch the screen anywhere. You'll see the color appear immediately, as if you're holding a crayon or pen. If you make a mistake, touch the Erase tab and use your finger to remove the offending strokes.
Save and Share Your Work
When you've finished your masterpiece, make sure you share it with your friends. You can post it to Facebook or send it via e-mail or text message.
And remember to save your work to your device! You can make sure you never lose a project by selecting "Auto save" in the app's Menu settings. Then anything you're working will automatically be preserved for you whenever you exit the app. Happy coloring!
That 5.0 star Google Play rating is generated by just two ratings. However, there is a free version in Google Play that has a 4.2 star average and 178 ratings overall.
The app is downrated because some bugs. One person, however, said the app said there was insufficient RAM on his phone, but then didn't list the phone. There are quite a few Android phones with minimal RAM and would not necessarily downgrade the app for that.
That said, there are other ratings regarding the app not working, as well.

Amazon.com opened up the Appstore despite a lawsuit by Apple, which has previously trademarked the term "App Store." Microsoft has filed an appeal against that trademark, saying the term is too generic. Amazon.com has responded to the lawsuit in the same manner.
