Get This Deal

For just $139.99, down from its list price of $169.99. This is $12.89 below the 30-day average of $152.88 and more than $20 below the 90-day average of $160.19. If you have been watching this band since launch, the price has not moved much until now.

What You're Getting

The Index Sleep Monitor straps around your upper arm, not your wrist, which makes it a better fit for people who find wrist-based trackers intrusive. It tracks sleep score, sleep stages, HRV, and duration of rest. The band also measures breathing variations via Pulse Ox and uses skin temperature data for advanced women's health tracking, including period predictions and past ovulation estimates. Battery life runs up to seven nights per charge.

If you already own a Garmin smartwatch, data syncs automatically through the Garmin Connect app. If you do not, the band can still send metrics directly to the app on its own.

Who This Is For

Best for anyone who wants detailed sleep data but cannot stand wearing a watch to bed. Side sleepers, people with sensitive wrists, and Garmin ecosystem users get the most value here.

Skip this if you only need basic steps and calorie tracking -- a standard fitness band covers that for less.

Final Verdict

For $139.99. This is the lowest the Index Sleep Monitor has been outside launch pricing. If you prioritize recovery metrics and sleep quality analysis, grab it now rather than waiting for a deeper cut that may not come anytime soon.
