When it comes to affordable sleep tracking, there are a variety of options available, including smartwatches, fitness trackers, earbuds, and non-wearables.

Smartwatches are a great option for sleep tracking, with the added benefit of having multiple other features. The Apple Watch Series 10 is one of the best smartwatches for sleep tracking. It has a bigger, brighter, and thinner display, a faster-charging battery, and a new water temperature sensor.
