iphone app to popup a reminder before sunset depending on location
Need unencumbered source code for iOS app on iPhone iOS 6 and iPad that will pop up a reminder at a specific number of minutes before or after sunset or sunrise based on the location of the individual. Users would register via a simple backend, and then select either sunrise or sunset and the number of minutes from that time.
The user's profile would remember the choices and remind the person each day at the specified time. Should work without the back end so long as the user has logged in, so it cannot depend on cellular or wifi data. It must be stored locally and on the back end. First phase could store everything locally. The Popup could be a fetched audio snippet, or one included in the code set into the system for phase one. I'll provide the audio snippet to play.
