The downside is it's only available for iPad. We love the new 3D painting features, which mean you can now create pretty much anything you like on the app. Plus, Procreate's colour library is like no other with its ability to create your own palettes, colour options and even colour recommendations.

From the colour picker to the brush size, there are so many options to help improve your workflow. Our testing asserted that Procreate's biggest selling point is its flexible and customisable interface. However, if you're wanting to know more about this brilliant app then have a read through our Procreate 5.2 review.

The app has taken the digital art world by storm with its many different functions, versatile interface and 3D painting abilities (it's actually compatible with Zbrush, Blendr and others).
