Hand-picked smart rings that work with the Ringlo app. Two we wear daily; the rest share the same chipset family and look right for the role.
Minimalist titanium and matte finishes. The "default" smart-ring look.
One ring per category — patterned, signet, and gemstone finishes for buyers who want something other than a plain band.
Sold under multiple brand names — the same physical ring may also appear as “Retro Smart Ring,” “Vintage Smart Ring,” or unbranded variants from different sellers.
Before you buy, the things we'd want to know.
Ringlo speaks the BLE protocol used by the DL110 / Jtr16 chipset family — the same chipset inside most affordable smart rings sold on AliExpress, Temu, and Amazon. The "Verified Compatible" rings are ones we wear daily and have confirmed working end-to-end with every Ringlo feature. The "Likely Compatible" rings share the same chipset signature in their listings (heart rate, SpO2, blood pressure, sleep, plus a SmartHealth/HBand/QRing/H Ring companion app) but we haven't individually tested each unit.
If you bought through Amazon or AliExpress and the ring doesn't pair with Ringlo, return it through the retailer's standard return policy — both stores accept returns on most smart rings within their normal windows. Ringlo cannot guarantee compatibility for rings outside the Verified Compatible list, which is why we label them "Likely Compatible — Untested." If a Likely Compatible ring fails to pair, please email us with the listing URL and we'll add it to our incompatibility list so other users avoid it.
Because they often are. Many of these rings share a common OEM hardware platform — different sellers slap different brand names on the same physical product. The COLMI R02 is the most visible example: it's sold under the Colmi brand on both Amazon and AliExpress, but you'll find rings with identical features and dimensions sold as "Smart Ring," "Anarow," "WXPRLK," and a dozen other names. If two rings have the same chipset signature, they almost certainly behave the same with Ringlo.
Ringlo offers a 14-day free trial — full access to every feature, no credit card required. After the trial, $3.99/month or $29.99/year keeps your sync, history, and trends working. Most rings on this page also work with their original "free" companion apps (SmartHealth, HBand, etc.) but you'll get the broken translations and creative sleep math we built Ringlo to replace.
