This can be as simple as using a photo, or as detailed as capturing all the information in a nutrition label. While it doesn't automatically log what you eat by using OFR (optical food recognition) or anything cool like that, Up allows you to log your food by picture, keyword and/or barcode scanning of labels. If you're looking to fully capture your entire fitness/health profile you also log your food in the Up by Jawbone app (free, App Store). But then there's also nutrition monitoring. Plus it's tough to fit Up's 3.5mm headphone jack into the iPhone port when using cases that don't provide enough clearance.

This means that syncing Up requires a manual step to sync your data, where FuelBand can sync wirelessly. This is surprising because of the pervasiveness of Bluetooth in Jawbone's headsets and speakers. You sync it by removing the stealthy silver cap (which could be easily lost) and inserting it into your iPhone's headphone jack.

The Up band only syncs to the iPhone manually, not over Bluetooth like FuelBand. Although you still have to choose between three sizes (S, M, and L) for the best fit. First, Up uses a wraparound, clasp-less design, which makes it slightly more flexible when it comes to size than FuelBand. Up is different from FuelBand in a couple of ways.

Jawbone took its time and released the Rev B Up in December 2012. Jawbone first released Up in December 2011, but it was plagued by hardware problems that forced Jawbone to issue refunds and go back to the drawing board. Some background on the "Rev B" moniker is probably in order.
