Thanks for the response Nic and rragan.
rragan - yes I could attach locally to a cache in geosphere without worrying about it being uploaded online, and have done this with a couple of hundred caches, and of course am now in the boat where I need to work out how to save that info from geosphere for my records.
Nic - Is it likely that adding a photo locally to a cache is on your list for an upcoming version as well?
Another request too is for a messaging option to be added to cachly for when you need to message answers to COs for earthcaches etc., so we don't have to use the official app for that, it seems that is the one thing everyone still seems to be using that app for, so would be great not to have to any longer - is this likely in the near future as well?
Headed out for a day of caching today, and used Cachly for all 31 finds without any dramas. Thanks for the app, and for such great response to help/suggestions from users!
