Random question. I just downloaded the app what’s my user name? Or where can I find it. I usually sign in w my email address but it’s saying invalid. Thanks 
Ummm, as far as I know there tudiabetes doesn't have an app for android or iphone. If you wish to use tudiabetes, you can simply use your browser and it will automagically recognize you are using a mobile device and employ a simplified interface. Is that what you are doing?
