Rogbid Loop W: a $59.99 screenless tracker with ECG
Rogbid's new Loop W fitness tracker costs $59.99 and has no screen, putting it in the same camp as Whoop and Oura at a much lower price. It tracks heart rate, blood oxygen and sleep, and takes 30-second ECG readings. Rogbid claims up to 30 days of battery life. Nobody has tested any of that independently, which matters if you plan to trust it with health data.
The Rogbid Loop W has no display and alerts the wearer by vibration.
The hardware
The body is 316 stainless steel. Calls and messages arrive as vibrations from a built-in motor, so there is nothing to look at on your wrist.
Inside sit a JL7073 processor and a Goodix GH3228 heart-rate sensor. The band monitors pulse, blood oxygen (SpO2), heart rate variability, stress, skin temperature and sleep stages around the clock. It pairs over Bluetooth 5.3 with phones running Android 9.0 or iOS 10.0 and newer. A Family Care mode lets you share your stats with relatives.
The tracker pairs with a phone over Bluetooth 5.3 and syncs through Rogbid's app.
The Loop W is rated 5 ATM for water resistance, meaning it is built for swimming and showering. Its 150 mAh battery is rated for 25 to 30 days of normal use and up to 60 days on standby. A full charge takes about an hour. That is a big jump from the 10-day claim on the earlier Rogbid Loop V.
Why no screen
Screenless bands are the fastest-growing corner of the fitness market. Sales rose 88% between 2024 and 2025, according to Entrepreneur, driven by Whoop, Oura and Google's Fitbit Air. Rogbid is also pushing into other wearables, including its $130 ZenRing smart ring.
The catch
Everything runs through the phone app. The Gadgeteer flags that as a drawback, since a dead app or a sync problem leaves you with no data and no display to fall back on. Rogbid also hasn't said how the app handles your health information.
The ECG, SpO2 and stress features are the other open question. The Goodix sensor is confirmed, but we found no independent accuracy tests and no confirmed medical clearance in the US or UK. Treat the readings as wellness estimates, not diagnoses.
Availability
The Loop W is on Rogbid's online store at $59.99 in Tech Black and Moonlight Silver. It ships internationally, but local pricing, shipping costs and import fees aren't listed. As of October 2026, UK chains such as Currys, John Lewis and Argos don't stock it. Waiting for independent reviews is the safer move.
