Easy Shot Email Cam is a really basic camera utility. The reason I like it: students can only take one picture at a time and email it all from the same application. There is not a lot to say about the actual functionality of the app; it is pretty straightforward.
How this applies to teachers you ask? Teachers (primary in particular) need an app that easily allows students to take a picture of their work and email it quickly. Students could share what they accomplished during math or word study. How easy is it to remember what every student accomplished with his/her unifix cubes during math without meeting with every single child and taking notes? It just isn't possible. This app would allow you to receive the proof that Jimmy or Suzy were able to accomplish a few tasks when you were not able to meet with them on a one-on-one basis.
