SleepScore™
Overview
SleepScore represents an innovative approach to non-contact sleep tracking on mobile operating systems. Developed through extensive research spanning millions of recorded sleep hours, the application leverages active sonar technology to monitor acoustic reflection patterns caused by chest movements during respiration. By transmitting ultra-high frequency acoustic waves through the smartphone speaker and measuring the micro-Doppler shifts bounced back to the microphone, SleepScore analyzes chest movement and breathing rates to estimate sleep stages without requiring a physical wearable device or mattress sensor.
The core functional matrix of SleepScore centers on a daily composite score ranging from 0 to 100, alongside precise classification across four distinct sleep phases: light sleep, deep sleep, REM sleep, and period awakenings. Beyond descriptive tracking, the application functions as a behavioral change engine. It provides tailored 7-day sleep challenges addressing bedtime consistency, caffeine intake, stress management, and bedroom environmental optimization. Additionally, SleepScore includes an integrated smart alarm clock designed to detect light sleep states within a user-defined window to minimize grogginess, as well as exportable clinical reports that enable users to share longitudinal sleep data with physicians.
From a technical perspective, sonar-based mobile monitoring introduces unique engineering trade-offs. Unlike optical PPG sensors built into smartwatches, sonar tracking eliminates tactile discomfort during sleep, lowering user attrition. However, sonar efficacy depends entirely on device-specific acoustic hardware calibration. Because variations in Android microphone response curves and speaker amplification alter signal fidelity, SleepScore historically validated specific OEM flagship models, such as select Samsung Galaxy S/Note series and Google Pixel devices, while placing broader device populations into structured testing programs. Environmental acoustic variables, such as high-velocity ambient cooling fans or localized white noise, can interfere with signal reflection, requiring robust signal filtering algorithms to prevent automated wake-state misclassification.

FAQs
How does SleepScore monitor sleep without a wearable device?
SleepScore utilizes active sonar technology. It emits silent, ultra-high frequency sound waves from the phone speaker and uses the microphone to measure reflection patterns caused by breathing and physical body movement during rest.
Is my Android phone fully supported by SleepScore’s sonar technology?
The application is officially validated for specific hardware configurations, including select Samsung Galaxy and Google Pixel devices. Unvalidated Android models can participate via an in-app beta enrollment system to assist in validating localized acoustic hardware.
Can the generated sleep reports be used for medical evaluations?
SleepScore generates comprehensive sleep reports summarizing sleep architecture, efficiency, and wake events over time. These reports are designed to assist medical doctors and sleep specialists during initial clinical consultations.
Does ambient bedroom noise like a fan affect tracking precision?
While the underlying algorithms filter constant background frequencies, extreme ambient noise or high-velocity air movement directed at the microphone can occasionally impact signal reflection accuracy.
What features are unlocked with the premium subscription?
The premium subscription unlocks an extended historical sleep log, deep sleep coaching programs, customized recommendations, and downloadable doctor reports.
Hot Reviews
Summarized from Google Play reviews and community discussions.
Feedback underscores technical instability in the alarm subsystem, where users report alarms entering continuous snooze loops that require device reboots to disable.
Reviews document stability issues on unvalidated Android builds, where the application terminates unexpectedly overnight, resulting in missing logs.
Users highlight the application's ability to cultivate healthy bedtime routines, noting that tracking nightly hours helped replace late-night habits with consistent sleep schedules despite background noise.
