GeoLog

This app overlays and saves location information stored on photos.
When looking back at photos taken in various locations, you might find it difficult to remember where a particular photo was taken.
If you save the location information on a photo, it's easy to see at a glance.
You can also crop and overlay map images from Google Maps,
and even display the current weather forecast for that location using past weather forecast data.
You can even display comments for each photo.
