My first iPhone app is submitted and in review by Apple, it should be approved soon, so make sure you go and download it in the App Store!  Here are some screenshots to give you an idea of what it is:

This app may not look like it does much, but it really takes care of a lot of the painful details.  For example, timezone and daylight savings time offsets.  This is a detail that you don't have to worry about, just pick a location, and we use the timezone of that location, and also automatically calculate if daylight savings applies to the given date, and of course perform the detailed calculation of the sunrise, and sunset, along with the others.

You can also use the current GPS location of the device, this will cause the calculations to use the current coordinates along with the current timezone specified in the device.

The location tab gives you over 10,000 world locations to choose from, so you can find the sunrise and sunset times for basically anywhere you'd ever want to go(or dream of going).

Uses for Sunrise and Sunset times

You can really do a lot of fun things if you know when the sun is going to rise and set:

  • Plan a romantic date, even if it is last minute, you can know what time the sunset is going to happen
  • Know when to wake up for an early morning sunrise hike(this is how we took the picture that is on the background of the app)
  • Important for photographers(like my wife) who want to take advantage of the prettiest lighting of the day.  If you need to plan your photo shoot weeks in advance you can quickly use this app to know what time to plan for.
  • Know when not to drive to keep the sun out of your eyes.
  • If you are planning to go camping, know when you need to get your tent setup before it's too dark.  At the end of civil twilight, it's no fun setting up a tent in the dark.
  • If you are a student and live in the basement of the library, or computer lab, you can know what is happening outside, without ever needing to go outside!
  • I'm sure there are a lot more!

Anyhow, I will announce when the app is released.  The first update to the app will fix a lot of things in the first version that we changed last minute.

Update 3/31/2009
