Black out seems to be a great app that does simply what it promises: An easy way to black out content on images and save / share the images afterwards. The interface is clean, and easy to use and the most important things are always visible and built-in. I will continue to use it in future and it saves me doing the same task in more complex, slow to load image editors.
I'm fairly new to doing graphics, and usually use Preview for this. It works but Black Out is much easier and no metadata worries. Thanks! I'll be recommending to friends.
