WhereOrWhen

When was I at this location?  Where was I on these dates?  Based on your photos, this app gives the answers. They are shown in: 
*  a list,
*  a page of photos,
*  a slideshow and 
*  on a map with lines between locations.
If you have a lot of photos in your iPhone (or iPad) the answers will be very detailed.  

One feature that could be very useful for us travellers: It can generate a trip map for all past trips if you took photos with an iPhone.  Two of the screenshots show off this feature.  The second map has the lines connecting locations hidden, if the distance between photos taken exceeds 1000 kilometres. This simplifies the map by eliminating flights. 

To get started just tap on one of the app selection boxes to choose either when or where.
