SOTA DB - MacSOTA DB is a Mac App to view the SOTA database.
Pocket SOTA allows you to carry the Summits on the Air (SOTA) summit database with you on your iPhone or iPad. With the app you can dig into the Associations and Regions worldwide, plot summits on the map, view some SOTA related websites to submit spots, update the database and view all summits in a region.
You can drop a pin on the map and find summits nearby.
When viewing a summit's details, you can calculate azimuth and distance to the peak from your current location using GPS.
