More information about Garmin’s new sleep tracking device has come to light. This device, reportedly named the Index Sleep Monitor, was first mentioned in May 2025 as a potential rival to the Whoop 5.0, which currently retails for $199 on Amazon.
Device Specifications
A recent article by Fitness Tracker Test appears to confirm the name ‘Index Sleep Monitor’ and provides additional insights. It was previously believed that this device is meant for the upper arm, and now we know it will feature a Velcro strap that is both comfortable and adjustable. The wearable will utilize an optical sensor, likely the Garmin Elevate Gen 5 sensor, tucked away in a pocket on the strap. An LED light next to the sensor may be there to show the battery level; it is anticipated that the device can track sleep for roughly one week on a single charge. In addition, a built-in vibration module is designed to wake the user gently, and tap gestures will be supported.
Features and Functions
The Garmin Index Sleep Monitor is anticipated to include functionalities such as monitoring sleep stages and duration, along with an overall sleep score. It might also track heart rate, SpO2 levels, and skin temperature, providing users with a Body Battery score. These features already exist in other Garmin devices like the Venu 3 smartwatch. Therefore, it’s not clear why Garmin expects consumers to prefer this sleep-specific wearable over their existing options. Moreover, it seems to offer fewer features compared to the Whoop 5.0, which includes fitness tracking capabilities.
Availability and Pricing
Newly released details indicate that the Garmin Index Sleep Monitor will come in two sizes, S-M and L-XL, priced at approximately €170. It is projected to be launched before August, although Garmin has not yet officially recognized this product. The sources for the report from Fitness Tracker Test remain unnamed.
