I have been using Accu Chek “Smart Pix”. A small device that plugs into PC (does not work on a mac, grrrr) and receives date from the meter via infra-red.
It gives me heaps of reports that can occasionally pick out trends but then it is up to me to test rigorously at the exact same times etc… Only as good as the user eh?? I tend to save them as a PDF and whizz them off to the docs.
