You can add in carb value and insulin units but there is no food look up functionality.
The graphs aren't as good as my iPhone app (diabetes diary with 4.8 on icon if anyone interested) so I've not bothered inputting as I also keep paper record and that would be just too much faffing!
When I say it's accurate, it was a laymans view... Obviously used tester fluid, but more to the point, if you get a high reading, say, I always double check before I take correction dose as I'm insulin sensitive. If u test with one finger and another, or indeed same one, it gives you same reading. My contour can fluctuate a bit .
