Simple Android app for converting between GPS Week/Seconds Time and local date time

The date time used by the Global Positioning System (GPS) is normally expressed as a week number and a seconds-of-week number. This format is not as easy to work with as a normal calendar date time. I made this simple Android App for converting the GPS Time (in week and seconds-of-week format) and local calendar date time (in UTC+offset format), which is easier to work with. It has the option to choose which local UTC time zone to use for conversion. The app will automatically adjust the local time for GPS leap seconds.

Clicking on the buttons will bring up pickers for selecting the input values, as shown below.
