landscape - Are there any mobile applications that calculate sunrise/sunset based on location?

Do you know a mobile application that would:

• calculate sunrise/sunset/twilight time


• calculate moonrise/moonset/moonphase


• would do that based on the location from internal GPS module

There are good enough online resources available to do the job (for example timeanddate.com) given that you're happy to mess with the printouts, but I haven't yet found a decent application for mobile phone.

I think this question is relevant because for a landscape shooter timing is everything.
