When you launch the app, you can choose the dimensions of the image you want to create there are presets for various sizes, or you can go with a custom size. By its very design (and similarity to Microsoft Paint), the app is not really suitable for creating high quality art on your computer, however, for most simple image creation tasks, the app will work perfectly fine. Just like Microsoft Paint, the interface is incredibly simple, and easy to use. The free app is exactly the same as its Windows’ counterpart, and has all the tools you’d find in the Paint app, right down to the spray can. If you’re looking for an app that works exactly the way Paint does on Windows, look no further than Paintbrush.
