We use an Iphone5, with the premium app, for geocaching and often visit areas without cellphone coverage. I usually choose the caches I want to search for on a computer, load them into the 'saved' area on the phone and sort them by cities. For example: when visiting Spain, I chose caches on the route our tour would use and loaded a few caches by city; Madrid, Obeda, etc.. We can log the finds as we go and then send them when we have WiFi service.
We use the same method in the USA to pick caches on our route before we go rather that search as we travel. This saves us from wasting time looking at all the caches in the area that may not have been found lately or are too far off our route.
I don't see that capability in the new version. Will it be added soon?
Thanks,
