The logging behavior you are looking for is the reason I switched all logging to local Cachly phone drafts and then uploaded as drafts (aka field notes) to the web site. It allows me to edit locally until I upload and then look at the logs on a real computer before I submit them. I was making too many typos and not writing out everything I wanted from my phone and this approach addressed that. Even if I have a full cell signal I still log it locally as a draft and submit it after I'm back home as a draft to the geocaching site.
