The Best

I have tried all the major caching apps, and this is the only one that I have not deleted.

It offers the best display for cache information. Its ability to import caches, filter, merge lists, and export gpx files lets it act as a mini-gsak.

I use Geosphere to keep track of puzzles that have been completed, qualified challenges, or other caches that I particularly want to do. It quickly loads pocket queries or performs live searches, allows me to filter and map the results, and offers a beautiful display of cache pages. I can easily export the results to my handheld gpsr or use the app to cache with the iPhone. And it interfaces nicely with routing apps to get me where I want to go.

Did I mention that you can also edit caches, view the underlying html, and ignore caches fr within the app?
