Zen: Coloring book for adults

All in All a very good app. But it should not be advertised as a free app. When you install it, all you get to do is LOOK at all the pretty art!!!! If you want to color any of it, you have to pay $2.99 to unlock the app. But it is worth $2.99, it just is not free as advertised.

Everything I expected, and more! No problem on my 4 year old PC, with Windows 10. I didn't buy any additional "art" as there are already dozens of designs to choose from. You can custom-make any color by clicking on the palette, and a sliding scale offers endless combinations of brush strokes. I did the first abstract design with full saturation of colors, but thereafter, I "colored" my drawings with shading, water color, texture. Experiment. You can click the counter-clockwise button in the right-hand column to undo your last two or three strokes. I'm very pleasantly surprised by how well the program functioned, along with simplicity with the options to add unique character through texture, lines (black, white, none). Enjoy.

I've seen the intricate paper coloring books for adults, but I have difficulty holding a pencil so I never got one. This is SO MUCH BETTER! I can customize colors for unlimited possibilities. If I want, I can change colors, going back and forth, using new colors until it's just right. And with so many pics, I never run out of new pics to color. And I love having a new, different Mandala to color every day. I can color until I'm tired of coloring and just quit. It saves my progress! But best of all, IT REMOVES ADS WHEN YOU BUY IT. All for less $$ than a burger. Just buying one paper coloring book can be $15.00 or more. I can save my pics, then clear and color them again! I use my saved colored ZEN pages as puzzles with Puzzle Gallery's custom feature that allows me to make puzzles from ANY image. When I save to file, I can change the black lines to white, changing the whole look! So Pretty. I had no idea there were so many possibilities in just one game. Best $2.99 I ever spent!

I love the pics but some have places in the pic that isn't completed so you can't color it separately from the colors around it.

Enjoyed it at first. I paid the 2.99 for all the pictures. After an update I can't access them anymore. Emailed developer. No response. What is the deal? Either fix this or give me my 2.99 back and then I will delete it.
