Today I use iGeoKnife to do logging when I'm on a caching trip. When I get home I load geocache_visits.txt from iGeoKnife into GSAK on my computer, and then add trackables and pictures in GSAKs publish log feature, before uploading everything from there.
iGeoKnife has worked good for this, however, the app rarely gets any updates, and the interface of Looking4Cache is way better!
But since my main reason for using iGeoKnife is the possibility to write the complete log and then import it to GSAK, it's still more useful for me than Looking4Cache.
That's why I would like to request that you add the possibility to generate logs to a geocache_visits.txt file instead of uploading it directly to geocaching.com.
The last thing that's better in iGeoKnife is the function for importing GPX-files, I can just send a file in a mail to myself, and then open the file in iGeoKnife by simply clicking on it in the mail client.
I don't use iTunes, so file transfer through iTunes is kind of unusable for me...
Other than that, I really like what you've done so far, this app has big potential!
I really hope you're able to implement my requests, if you need help to do beta testing, don't hesitate to contact me! (cache (at) thomfre (dot) net)
