Spelunker_ app for iPhone and iPad

Use the Spelunker app to tag the name of the cave, take a picture of the entrance, and use the “Capture Longitude and Latitude” button to capture the GPS coordinates. Each entry will be stored in a cave "List”.

After you have saved a cave to your "List" you can select it. Selecting a cave from your cave list will take you to its detail page where you can:

- use the "Email" feature to email the details of the cave to anyone you wish.

- use the "Tweet" feature to send the details of the cave to your Twitter account.

- And if there is a photo of the cave present, if you touch on the photo, you will be taken to a screen where you can pan and zoom on the image. Double tap the image to re-center it to the screen.

To view the location of all entries in your "List" plotted on a map, tap the "Map" tab bar button. This will drop a purple pin onto the location of all entries in your "List". The map allows users to zoom in or out on locations. Choose between Standard, Satellite, and Hybrid.
