First of all let me thank the whole Duolingo team for a fantastic website and phone app. After using Duolingo for a couple of weeks I have a suggestion which may move it forward. As everyone knows, when you log into the website you are asked if you would like to use a microphone. This is great, as it really helps you get handle on pronunciation. However, the one thing everyone who has the app, has, is a microphone on their smartphone, yet there is no option to use it. Maybe you could look at this and in a future update include it.
