## At a glance

- Sleep summaries are described as viewable in the app by day, week and month, including sleep timing and light and deep sleep.
- The listing claims continuous heart-rate and blood-oxygen monitoring, plus step, calorie and distance tracking.
- Sport modes named in the listing include walking, running, cycling, hiking, yoga and golf.
- The app is described as having lifetime access without a subscription fee.
- Ring sizing follows US sizes. The listing recommends sizing down if using its circumference-measurement method, which may read slightly large.

## Pros

- No display keeps the tracking experience centered on the companion app rather than on-screen controls.
- A charging case is listed, and the seller claims it can recharge the ring about 15 times.
- The stated feature set combines sleep, health and everyday activity tracking in a ring format.

## Cons

- The ring has no display, so the listing directs users to the smartphone app to view tracking data.
- The claimed ring battery life is 3-5 days, so regular recharging is part of use.

## Before you buy

- The listing is inconsistent about water protection: it separately says Waterproof, IP68 and 50 meters, but does not explain the relationship between those claims. Treat the actual water-use rating as unconfirmed. It also lists Android Wear 2.9 for a ring that is described as pairing with Android and iOS phones, without clarifying the software role. Battery claims of 3-5 days per charge and up to 60 days with the case refer to different configurations. Confirm sizing against the chart and chosen listing before ordering.

## In the box

- Smart ring (Included)
- Charging cable (Included): The package list names a charge cable. The feature text specifies magnetic USB and Type-C cables, so cable details should be checked on the selected listing.
- Charging case (Included): The feature text describes a 400mah case.
- User manual (Included)

## A good fit for

- Buyers who want sleep and activity summaries in a companion app rather than on a ring display.
- People looking for a smart ring whose listing claims no app subscription and includes a charging case.
- Users with a compatible iOS or Android smartphone who want basic activity and health tracking in a ring form.

## Less suited to

- Buyers who need to read metrics directly on the wearable.
- Anyone who needs a clearly documented water-use rating or independently established tracking accuracy.

## Customer feedback

Customer feedback highlights the ring's appearance and comfort, with positive reports about sleep and heart-rate tracking, functionality and battery life. This aligns with the app-based health and activity features claimed in the listing, but does not establish tracking accuracy or confirm the stated battery duration. The rating distribution is mostly five-star, with a smaller range of lower ratings, so experiences are not uniformly positive.
- Positive themes: Customers reportedly like the design and comfort.
- Positive themes: Customer feedback describes sleep and heart-rate tracking positively.
- Positive themes: Customers reportedly appreciate its functionality and battery life.

## Frequently asked questions

### Does the ring have a screen?
No. The listing specifies No Display and describes viewing tracking information in the smartphone app.
### Does it require a subscription?
The listing claims lifetime free access to its health app without subscription fees.
### How long does the battery last?
The listing claims 3-5 days of ring use after a 2-hour charge. It also claims the 400 mah charging case can recharge the ring about 15 times, but does not establish a single unconditional total-use figure.
### What phones does it work with?
The listing names Android and iOS devices and gives Android 4.4 / iOS 8.4 or above as compatible versions.
### What water protection should I expect?
The listing gives three separate claims: Waterproof, IP68 and 50 meters. It does not explain how they relate, so the specific water-use rating remains unclear.
