I have a bend is jewbone up3.
Jawbone originally had big plans for its UP3 fitness tracker.
When it was first announced, Jawbone was happy to boast that the UP3 would be the first 24/7 tracker you could use to not only track your .
Sleep monitoring is one of Jawbone's strengths, at least when you can get it activated.
Thankfully that new firmware update means it can now be done automatically .
I tested the automatic sleep tracking against the Fitbit Charge HR, which offers the same feature.
The numbers kind of speak for themselves.
