Reviewing educational apps is an important service. There are so many apps now available and the names can sound so familiar it is difficult to sort through what might be useful. Hence, there is a place for recommendation sites. AppoLearning is such an effort for the K-12 community. App recommendations organized by category with a rubric of sorts identifying specific attributes you might want to consider.
BTW – we also have an app recommendation site. Our approach is based on our own experience and considers far fewer examples. We do offer a little more depth in out comments. Our site is likely of greater interest to the technology coordinator/facilitator.
