App smashing has become a pretty popular phrase in the edtech crowd. It just means using multiple apps to accomplish something that wasn't possible in any of the apps individually. We've been working on a One Word project here at HSE. See this HAWK Talk from Mr. Phillips for more information.
I've been walking students through some steps to app smash a picture using the camera, photos, and Educreations. We were able to have students quickly add text, crop, and apply a filter to their photo to participate in the One Word Project. It opens up a whole new set of possibilities for our tech learners to think of a project in mind, then apply more than one app to the project.
