## What is Tutu?

Tutu is a calm little coloring studio for iPad and iPhone.

Pick a picture, follow the numbers, and fill it in — or turn your own photo into a paint-by-number coloring page, entirely on your device.

- Beautiful built-in line art with matched palettes
- Turn any photo into a numbered coloring page
- A smooth zooming canvas: draw with Apple Pencil on iPad, or tap to fill with your finger on iPhone

On iPad, drawing and coloring require Apple Pencil. Fingers pan and zoom the canvas. On iPhone, tap regions with your finger to fill them. Due to the smaller screen, iPhone does not support freehand drawing or direct line-art image imports at this time.

### 5/5 — Actually let’s you color

*2026-09-01*

This app is fantastic.  I get to color instead of just tapping and the color automatically filling.

### 5/5 — Best paint/color app ever!

*2026-07-31*

My favorite most realistic coloring app ever! it’s just like doing a real paint by number! Have to stay in the lines and actually do it! I’ve been waiting for an app like this for so long! The only thing I wish is that there was a way to change language, I can’t read anything on the app. Other than the language issue this is by far the best app ever! I’d buy pro if I could read the benefits of it.

### 5/5 — 很棒！宝藏软件

*2026-07-22*

特别特别特别棒的一个软件，无意中点击下载了这个软件，对于为了找事情打发时间的人来说很nice，首先就是他的数字很清晰，不管放多大数字都很清晰，而且最重要的是如果图的时候把数字涂上了，他可以隐藏画的涂层，直接就可以看到被涂掉的数字是哪个，不需要去分屏找原图，还有就是他也很方便，可以把图片转成油画，且有简单正常精细三个选项，而且也可以调整笔画大小，双指撤回，三指恢复，且可以直接铺颜色，对于ipad党，最好是有笔的宝宝来说使用很有体验感，宝藏软件哇！
