Hi!
I installed Geosphere two weeks ago and it's a really useful tool for paperless geocaching. Meanwhile we did some geocaching tours and using the app was really fun!
Generate a PQ on geocaching.com, follow the link in the mail or select the PQ in the built-in browser, download the gpx file and you're done!
All needed information including pictures, the last few logs etc. are vizualized very good and you can also record field notes and upload them directly from the app. On geocaching.com you can afterwards convert the field notes into logs. Very nice!
Filtering for cache types, difficulty, terrain, etc. directly in the app is also very useful!
I can really recommend the app - but you should take some minutes to get familiar with it before you start your first trip in the field!
Have fun,
