I just started using the Lose it app to log food. I was using the FitBit app for that, but this one is much better. Probably the coolest thing about it is the barcode scanner. I have not found an item that it won't scan. Even the Costco Kirkland stuff scans perfectly. It also syncs with my FitBit and FitBit scale. I'm thinking about getting the Withings BP monitor because it syncs with that as well. Just wanted to share, in case others want to check it out.
