Unofficial: based on user reports. Yes, you can wear the Amazfit Helio Ring alongside an Apple Watch, but the data does not fully merge inside Zepp. Helio/Zepp data can coexist with Apple Watch data in Apple Health; Apple Watch workouts may remain in Apple Health and not flow back into Zepp.

Some features missing

Both can use Apple Health, but Helio sleep doesn't become Apple Watch sleep data.

Users report wearing both devices and seeing some Helio data in Apple Health or third-party apps. Syncing isn't two-way for Apple Watch workout data, so Zepp may not have the full Apple Watch activity history, and the Apple Watch sleep app doesn't adopt Helio Ring sleep results. You need an iPhone with the Zepp app and Apple Health permissions enabled; both supporting reports are older than 12 months and should be rechecked after major Zepp updates.

How we read this
  • We read store prices every day and keep every read. The price shown is the newest read from the retailer named.
  • A read older than 36 hours is never shown as the current price. It reads "last seen" and carries no buy link.
  • “30-day low” is the lowest of our own reads for this product in the last 30 days, not a retailer’s claim. We print the number of reads beside it, and we say nothing about a low until a product has a week of reads.
  • “Lowest known”, where it appears, is older price history from published reports and imports. It is shown only when it is lower than the 30-day low, and it is not counted as reads.
  • Our advice comes from the price, the price history and whether a newer model is coming. It never depends on who pays us.
