One's a tiny band, one's an affordable clip-on: look at Jawbone's latest health wearables hitting this year.
The Jawbone Up3, available later this year, is still a fitness band: much like the Jawbone Up24, it doesn't have a display.
It adds continuous heart rate tracking, but it does so in a much smaller size than other trackers.
The Up3 comes in several designs, but this silver and grey one won't be available this year. It's a sleek design, and looked good on my wrist.
The black version will be on sale this year for $180 in the US, or £150 in the UK.
To measure heart rate, the Up3 uses bioimpedance, instead of the green LED optical technology in other wrist bands.
One size fits all: a new watch-like clasp on the Up3 attaches easily and looks elegant.
The band's designed to be worn on either wrist, and can be submerged in up to 10 meters of water.
Nightly sleep analysis gathers baseline resting heart rate, which Jawbone's Up app will use a measure of health.
A closer look at the strap mechanism designed by Yves Behar, the designer behind the look of Jawbone's other devices.
The band material feels like soft-touch silicone.
How small is the Up3? Here it is next to last year's Up24. It makes the old Up seem positively bulky.
The clasp mechanism is a lot better than the old Up's coil-like design, and the pop-off end cap is gone.
The Up Move is only $50 (£40 in the UK) and will be available in November. It's a basic activity tracker.
Much like the Misfit Shine and Flash, the Up Move pops into various wrist bands and clips.
It also comes in different colors and designs.
The Up Move doesn't measure heart rate, but tracks steps and sleep like last year's Up24 band.
Its replaceable coin-type battery lasts six months, no charging needed.
The wrist strap attaches securely.
It's small for my wrist, but the Up Move's certainly affordable.
