Finding good quality learning apps that actully enhance learning can be tricky. We spent several hours researching and testing educational ad learning app.
Based on out research, we think a good learning app should be provocative, exploratory, and open-ended. It should have been designed with primary input from educators and curriculum developers, or shown in educational research to be an effective learning tool. The apps we cover in this guide are greate learning apps not because they're designed to make kids smarter, to drill facts, or to replace in-school learning, but because they're fun and interesting for all.
