Error? Every single time?

It looks like it would be a great app to alert you to the flight information, if it actually let you create the alert. Every time, no matter which method of alerting I select, or which alerts I select, when I try to save my choices, it says "error, please try again." I see the same comment in almost every review I am reading now. Doesnt the software developer read these comments? I give it one star because it wont let me give it zero.
