CNBRO Ring + Ringlo: Better App, Same Ring
The CNBRO is a vintage signet-style smart ring sold on Amazon. If it ships with a YCBT companion app, Ringlo replaces the stock experience.
About the CNBRO ring
The CNBRO stands out for its retro signet face — a different look from the usual plain bands — while tracking heart rate, blood pressure, SpO2, sleep, steps, and calories. It's waterproof and sold without a subscription. The same physical ring often appears under other names like "Retro Smart Ring" or "Vintage Smart Ring," which is typical of this OEM hardware family.
Does it work with Ringlo?
Likely yes — verify before relying on it. Ringlo works with smart rings that use the YCBT protocol — the same rings that pair with the SmartHealth, HBand, Wearfit, or YCBT Life apps. Most affordable AliExpress, Temu, and Amazon rings (DL110 and similar, on the Actions Semiconductor ATS8266 BLE chip) use it. We list the CNBRO as Likely Compatible because we haven't tested every unit individually.
Before you buy: confirm the listing says it ships with the SmartHealth, HBand, Wearfit, or YCBT Life app. Those use the YCBT protocol Ringlo is built around. (Colmi R02/R03/R06/R10 also work on the QRing/Colmi Fit BlueX firmware; for other rings on those apps, download Ringlo and tap scan to check yours.)
Why use Ringlo
- Clean dark-mode dashboard, no ads or machine-translated menus
