It is as easy to use as Lucidpress, but I feel it's main goal is for web based graphics, much like the "infographics" you see. It has templates for many things such as Twitter headers, Google+ Photos, Photo Collages, etc.
Here is an example I did in about 5 minutes:
Teachers and Coffee
You can easily download the images to be used however and wherever you wish.
The one thing that I do not like is that it is not integrated with GDrive like Lucidpress is. At any rate, it is a very useful app that I imagine many of my students will enjoy using this year!!
Try it out and let me know what you think!!
