Paintbrush is a Microsoft Paint clone for Mac - in other words, a basic picture editor that even kids will find easy to use.
It's not often that a Microsoft product gets remade for Mac but Paintbrush is more or less a version of MS Paint which comes by default with Windows - you know, the kids app that you never used when you were on Windows. Be warned that it's not quite as simple as Paint, but it follows a similar pick-up-and-paint format and is easy to learn with just a little perseverance.
Paintbrush is an extremely simple app – don’t make the mistake of thinking it’s a photo editor or replacement for an image editor like Photoshop. You've got a toolbox which allows you to use a paintbrush, rubber, color palette, area selector and little more than that. In other words, Paintbrush won't appeal to any serious artist but it could be useful to keep your kids happy for a while or simply if you want to doodle a few minutes away.
You can save your Paintbrush masterpieces in most major formats, although you can only select one default save format (.PNG). It's not easy to paint on Paintbrush when using a mouse, however; the app should support the addition of a light-pen and pad to make it more usable.
Simple to use and easy to get going, Paintbrush is the blank canvas that will take you back to kindergarten.
