COLMI R02 + Ringlo: Better App, Same Ring
The COLMI R02 is a popular, well-built budget ring — and it works with Ringlo on both of the firmwares it ships with. Keep the ring, change the app.
About the COLMI R02
The R02 is one of the most recognizable affordable smart rings: military-grade titanium, IP68 + 3ATM water resistance, and tracking for heart rate, blood oxygen, sleep, and basic sports. It's sold on both Amazon and AliExpress under the Colmi brand and is frequently rebadged by other sellers.
Works on both firmwares. COLMI R02 units ship with different firmware depending on the seller — but Ringlo handles both. Units that come with SmartHealth, HBand, Wearfit, or YCBT Life use the YCBT protocol; units that come with QRing or Colmi Fit use the BlueX protocol. Either way you get heart rate, SpO2, sleep, and steps. Blood pressure is available on the YCBT firmware only — not on the QRing/Colmi Fit (BlueX) path. The R02 is supported via BlueX with Bluetooth bonding; the R10 in this family is hardware-verified.
Not sure which version you have? It doesn't change the answer.
- The companion app on the listing tells you the protocol — SmartHealth / HBand / Wearfit / YCBT Life = YCBT; QRing / Colmi Fit = BlueX.
- Ringlo pairs with the R02 on either protocol, so you don't have to match the app before buying.
- Already have one? Just download Ringlo and tap scan — it shows up in about 10 seconds.
Why use Ringlo on your R02
