Echo Prof app for iPhone and iPad

Echo Prof is a study aid designed to help you memorize information efficiently and with lower effort than other memory apps.

The app is designed such that it will ask you a question out loud, and you can respond out loud. This reduces strain on your eyes (since you do not need to look at the screen) and back (since you do not need to hold your device). The app is also really great for ensuring good pronunciation (because it uses speech recognition) and fluency (because you need to answer questions within 5 seconds).

Each time you answer a particular question correctly, the app will wait longer until it gives you a review.
