I am looking for a fitness tracker. All the usual features: heart rate, sleep, step counter, IP67, clock, alarm, etc, etc. Longer battery life is a bonus, so black & white display is preferable to colo(u)r.
I see some now which also claim to measure blood pressure, and am somewhat skeptical.
I am especially skeptical of those which claim to count calories. Are there any which are even close to accurate? Let's say +/- 10%
If so, I am looking for a recommendation. If not, then without. But, with blood pressure, if accurate. Otherwise, standard features, preferably with black & white display/long battery life.
Hmmm, is there also an answer with GPS? I don't really need it, as I have a Garmin Forerunner for running, but I am bit of a gadget junkie, so would like to know my options :-)
