"Sync" is the rage these days.  BUT can't users simply copy the db file from one device to the other as a temporary aid before you get the sync developed.

Yes, they will have to be careful not to write over old files containing new information; it would be best if they only use one device to input up until you develop the sync.   That is the beauty of a sync.

I've not looked at your app but will.  I prefer something where I can change the parameters to fit my situation.

Thx
