Sandbox Customer Insights

1. This is my #1 favorite app for a lot of good reasons and that won't change for a while.I would love to give it 5 stars but since it updated a couple days ago I sadly can't😥1st, the color bar at the bottom, I HATE how when you swipe it goes 6 colors at a time.FRUSTRATING and annoying! PLEASE go back to the other way where you can move freely between the numbers! And 2nd I HATE that the colors aren't blured(don't know how else to describe it).

2. Aside from that, you need a separate page that lists only uncolored or unfinished pictures instead of having to scroll through all of them.Great, but could use improvement Sandbox is great & super fun, I use it all the time in waiting rooms.

3. It has a ton of great pictures to color and lots of features that make coloring easy, fun, and relaxing.

4. I even got this before they made the finishing color animation faster! Every time this app updated it made it a million times better, including when they added the option to color photos from my gallery.

5. I might pay a one time price to unlock the extra pics, but I'm not dumb enough to ever give a monthly subscription price to color.

6. Someone would have to be crazy to pay a price every month just to color a few extra pictures.

7. I just wonder why they charge a monthly price for the premium pass to color the extras.

8. If I double tap one of the numbers on the picture, the rest of the squares of that color will become uncolored again.

9. I think it would be better with a slight social concept though, like some people make pictures that I really like & it would be cool to be able to follow them, so you can always find all of their pictures!I love this app.

10. It is fun to color and pass the time.

11. It has a couple nice features like double tapping to fill large spaces, a magnifier, and you can make & name different collections of drawings.
