If you are looking for more of a podcasting tool, you might check out Audioboo. This FREE tool is both app and web-based and also allows you to upload an image. The advantage is that you can record up to 3 minutes, pause and add to your recording without having to start the recording over as you do in Fotobabble. However, you cannot add effects or edit your image as you can in Fotobabble. Read more about Audioboo in education.
Annotate any image and have students share their learning. Take photos of a math problem, science lab, class work or a website and have students record their learning to share with parents and more.
