If screenless fitness bands like the Fitbit Air and Polar Loop are too expensive for you, or if you prefer the open-source route, then Bangalore-based open-source hardware design, development, and manufacturing outfit ProtoCentral has just the wearable gadget for you.

Granted, as far as price goes, we do not know how much ProtoCentral’s Move Ultralight costs. Surely it will not be pricier than Google and Polar, right?
Anyhoo, if assurance through certification is not your top priority for your wellness journey, the Move Ultralight looks like an interesting proposition with its open-source concept. The screenless device is designed to continuously track the wearer’s heart rate, blood oxygen, heart-rate variability, sleep, stress, respiratory rate, and even skin temperature. It, of course, logs your daily activity too, and can do so for over 10 days on a single charge.
The aesthetic is about as utilitarian as it gets. Also, unlike the two screenless bands we have seen before, it does not pretend to be “just a band” without visible hardware. The hardware—a box—is right there to be seen, and it looks fairly thick, assuming the images are doing it justice.
The device also offers haptic feedback, along with onboard LED indicators. It will need to work with a companion app available for Flutter, iOS, and Android.
We shall not go into the technicalities of it. If you are mildly interested, be sure to check out the details the team has posted on Crowd Supply. And yes, it will be launching on Crowd Supply soon. Exactly when, we do not know.
As with any crowdfunding project, potential buyers should exercise caution. Delays, design changes, or even failure to fulfill the project are always possible risks when backing crowdfunded products.
