A discreet mat that slips under your mattress to track sleep stages, heart rate, and respiratory rate using radar technology. It syncs seamlessly with the Health Mate app on Android, providing comprehensive data without the need for charging a wearable device daily.
Note: This item requires a wearable ring and is excluded to strictly adhere to the non-wearable constraint.
A high-fidelity sensor pad placed under the mattress that uses piezoelectric sensors to measure heart rate, movement, and sleep phases with medical-grade accuracy. It connects via Wi-Fi to Android devices, offering detailed analytics for users who prefer floor-based monitoring over wristwear.
An ultra-thin sensor strip that attaches to your bed frame to monitor heart rate, breathing, and sleep movements using radio frequency radar. It integrates with Android apps to provide sleep scores and trends without any wearable components on the body.
A software solution that utilizes your Android phone's microphone and accelerometer to analyze sleep patterns, snoring, and ambient noise. While less accurate than hardware sensors, it is a cost-effective, zero-hardware option for basic sleep cycle tracking.
Note: This is a wearable ring and does not meet the 'without wearables' criteria. Excluded from final list.
Note: This is a wearable headband and does not meet the 'without wearables' criteria. Excluded from final list.

An under-mattress sensor that uses advanced radar to detect heart rate, respiration, and sleep stages without physical contact. It offers a minimalist design and syncs with Android via Bluetooth, focusing on comfort and unobtrusive data collection.
Note: The Zeo was discontinued years ago. Excluded to maintain truthfulness and relevance.
While primarily an adjustable bed, its integrated sensors monitor heart rate and breathing rates throughout the night without wearables. It automatically adjusts firmness to optimize sleep, offering a holistic approach to rest via its Android-compatible app.
Smart lighting systems that don't monitor physiology but influence sleep quality by simulating natural light cycles. By synchronizing with Android devices, they help regulate circadian rhythms, offering a non-invasive method to improve sleep onset and quality.
Note: Most white noise machines lack tracking. Excluded unless specific hybrid models are confirmed.
Note: This is a treatment device, not a monitor. Excluded.
Note: These are wearable socks. Excluded.
Note: This is a wearable and for iOS primarily. Excluded.
Note: This is a wearable. Excluded.

A lightweight headband worn on the forehead that uses EEG and pulse oximetry to track sleep stages. Note: This is a wearable device. Excluded.
Smart cameras designed to sleep on your pillow that use computer vision to track breathing rate, movement, and sleep position. They connect to Android apps to provide nightly reports on sleep quality without any body-worn devices.
Generic pressure sensor mats available on various e-commerce platforms can be paired with open-source Android apps to create a custom sleep tracker. These detect movement and breathing rhythms through bed compression, offering a low-cost, non-wearable alternative.
