What App Works With My Cheap Smart Ring?
You bought a smart ring on AliExpress, Temu, or Amazon, the bundled app is rough, and you want something better. If your ring runs a protocol Ringlo reads, you don't need a new ring, just a better app. Here's how to check.
What app works with an AliExpress or Temu smart ring?
Most cheap smart rings run one of a few Bluetooth protocols. YCBT is the protocol behind the rings that ship with the SmartHealth or YCBT Life app. BlueX is the protocol behind the Colmi rings that ship with QRing or Colmi Fit. MoYoung is the protocol behind the rings that ship with the Da Rings app. Ringlo works with all three, so if your ring runs one of them, you keep it and simply change the app.
How do I tell which protocol my ring uses?
Look at the stock app your ring came with. Here's what we know:
| If your stock app is… | Your ring's protocol is… |
|---|---|
| SmartHealth, YCBT Life | YCBT, and Ringlo reads it |
| QRing, Colmi Fit | Usually BlueX (Colmi). Ringlo reads Colmi R-series rings; QRing rings named QRRM… have never connected |
| HBand | Veepoo, which Ringlo does not read |
| Da Rings | MoYoung, and Ringlo reads it: heart rate, HRV, blood oxygen, blood pressure and steps |
| Wearfit, Da Fit, others | Not confirmed, so scan with Ringlo to check |
If your app isn't listed, scanning with Ringlo is the quickest way to find out. The mapping mostly matters when you're deciding whether a ring is worth buying.
What is an ATS8266 or DL110 ring?
The Actions Semiconductor ATS8266 chip paired with the DL110 reference design is the ring Ringlo was built around. It speaks the YCBT protocol, and it's fully supported by Ringlo: heart rate, SpO2, blood pressure, sleep, and steps, plus HRV as a trend: the ring's hourly value, or an estimate from heart rate when the ring gives none. The DL110 is the ring the Ringlo team wears and tests daily, so it is hardware-verified.
Which rings work with Ringlo?
- YCBT / DL110 (ATS8266) rings: full support, verified. Heart rate, SpO2, blood pressure, sleep, and steps. HRV is a trend: the ring's hourly value, or an estimate from heart rate.
- Colmi R02, R03, R06, R10 on QRing / Colmi Fit (BlueX) firmware. Heart rate, SpO2, sleep, and steps. Blood pressure isn't available on the Colmi/QRing path. The R10 is verified on our own ring; R02, R03, and R06 rings have connected for Ringlo users. These rings require Bluetooth bonding.
- MoYoung / Da Rings rings (sold as H1, OW Ring, VR11 and similar, on the Da Rings app). Heart rate, HRV, blood oxygen, blood pressure and steps. Sleep, battery and temperature are not shown for these rings.
- V-Ring and SY rings (SY01, SY02, SR16, STILEFIX). Steps only. Ringlo shows the ring's own daily step count. Distance and calories are worked out from your height and weight, not measured by the ring. These rings also report heart rate, blood oxygen, HRV and stress, and Ringlo shows none of them: we have not checked those numbers against the ring maker's own app for the same ring on the same night, and a health number we cannot stand behind is worse than no number. Sleep is not shown either. The few sleep records these rings have sent us are not enough to put a sleep score in front of anyone, so Ringlo keeps what these rings send and shows nothing until it can be checked. No blood pressure on these rings. They require Bluetooth bonding.
- SR08 / Aolon (FEF5 family): new. The SR08 connects and pairs (Bluetooth bonding, and it streams on its own once connected). Heart rate and blood oxygen are supported, including the heart-rate history the ring stores. No steps, no sleep and no blood pressure on this ring.
- efe0 clones (Colmi-style R-series names, for example R9). Steps, heart rate and the ring's battery, including the heart-rate history the ring stores. No blood oxygen, no blood pressure, no sleep and no temperature on these rings. Ringlo now keeps the sleep records these rings hold, but does not show them: the reading has never been checked against the ring maker's own app.
- Any other ring: not supported. If a ring isn't YCBT, BlueX, MoYoung, V-Ring/SY, SR08/Aolon or efe0, Ringlo will tell you so during pairing rather than half-connecting. We used to read heart rate and battery from any ring advertising the standard Bluetooth services, and we removed it: on some of those rings the readings were nonsense (we measured heart rates in the tens of thousands), and a number that wrong is worse than no number.
Which rings don't work?
- QRing rings named QRRM… use a different chip and have never connected.
- TK16- and TK18-style rings (the f618 family) and rings that only work with HBand aren't supported yet.
- Bonding-gated rings that fail Android's pairing step won't connect.
- Any other ring is named as not supported during pairing, rather than half-connecting.
The 10-second check. The fastest way to know is to try it. Download Ringlo (free 14-day trial, no credit card), open it, and tap Scan on the pairing screen with the ring within a foot of your phone. A compatible ring shows up in about 10 seconds, then tap to connect. If nothing appears, charge the ring for 10 seconds to wake it, then scan again.
