Do you envision this logging to be a source for backups as well? I'm always afraid of a nook dieing in the field for a big match and losing the scores since the last sync. I really like the email feature too, that way shooters can keep track of their scores. QR codes seem too complicated to me, I think a simple approve button is sufficient.
Definitely. If necessary. The results can be filtered, so you can see all for a squad, a shooter, or a stage.
I rely on frequent syncing to handle devices dying. We are gearing up to add cloud sync, where a device's data goes to the cloud for synching and for backup.
That would be seriously awesome. We are already provisioning a wifi mesh network (lots of APs) for our coverage, but don't have an internet gateway attached yet. If this comes, we will definitely be adding one. Even with the frequent syncing, we still have the possibility of having to do a reshoot, but that's why we have paper for now. However, the paper is yet another burden to put on the RO and scorer. They have enough things to deal with.
