New affordable screenless tracker undercuts the Fitbit Air by $30 with ECG, fall detection

Rogbid has added the Loop V to its store at $69.99 in black and beige. It joins the Loop, which launched in March at the same price, and the $59.99 Loop Air from July. The listing leads with ECG monitoring, fall detection, and of course, no display.

The band pairs a GH3228T AFE with an RA2325 PPG sensor and a Bosch 270 six-axis accelerometer (the part that presumably handles fall detection). A 220 mAh battery is rated for up to 10 days of typical use, 5-7 days under intensive use and 30 days on standby. 

The case is aluminium alloy with a nylon strap, water resistance is 3 ATM, and the companion app requires iOS 13.0 or Android 8.0 or later. Rogbid also lists four-stage sleep tracking with bedtime recommendations, body temperature and menstrual cycle tracking.

Those figures line up closely with the Amazfit Helio Strap ($99.99 on Amazon), which uses a 232 mAh cell for the same 10-day rating, weighs 20 g and costs $99.99 without a subscription — though the Helio is 5 ATM to the Loop V's 3 ATM and has no ECG. Google's $99.99 Fitbit Air can run for seven days and adds AFib alerts, with core tracking free of a subscription. Whoop's MG hardware comes with the $359-per-year Peak tier.

The ECG comparison still needs a caveat. Ignoring the difference in price, Whoop's Heart Screener is FDA-cleared for AFib indication; Rogbid makes no regulatory claim here.

Fall detection is one of the most unique offerings here, since nothing else in this category advertises it. However, with no display or cellular radio, any alert would route through a paired phone. Rogbid has not explained sensitivity, false-positive cancellation or emergency contact notification on the Loop V's launch page.
