Best Sleep Trackers: Wearables and Bed Sensors Reviewed

Sleep tech has moved beyond step counts and basic heart-rate trends. TechRadar's latest roundup covers a range of sleep trackers — both wearable and non-wearable — that were tried and tested to see which devices actually help you understand your nights better.

On the wearable side, traditional wristbands and smart rings still lead for convenience. These devices typically track movement, heart rate, blood oxygen and sleep stages, offering a clear nightly summary in companion apps. They suit people who want continuous tracking and the ability to take data with them day-to-day.

Non-wearable trackers, such as under-mattress sensors or bedside devices, appeal if you prefer not to sleep with tech on your body. These gadgets use ballistocardiography, radar or pressure sensors to monitor breathing, movement and sleep cycles without contact. They can be particularly useful for couples or people who find wearables uncomfortable.

Which option is best depends on your priorities: accuracy, comfort, battery life and how much context you want in your app. Some devices focus on simple, actionable sleep scores; others offer deeper analytics and smart alarm features that wake you at an optimal point in your cycle. Integration with health platforms and sleep coaching features are increasingly common.

Price also spans a wide range, from budget trackers that cover basics to premium smart rings and mattress sensors with higher fidelity data. For many readers, a midrange wearable or a reliable under-mattress sensor strikes the best balance between comfort and insight.

If you're shopping for a tracker, think about how you'll use the data and whether you prefer a device on your body or one tucked away in your bed. TechRadar's tested picks aim to help you make that choice by highlighting devices that deliver consistent, useful sleep information.
