SleepScore Review (2026)
Sonar-based phone-only sleep tracker — no wearable, setup-sensitive accuracy.
7.3 / 10
SleepScore is the only meaningful sonar-based sleep tracker — it uses your phone’s speaker and microphone to detect breathing and movement. When the setup is right, it works. When it isn’t, it doesn’t.

Frequently asked questions
Does SleepScore's sonar approach really work?
In a well-controlled bedroom layout (phone within 3 ft, no fan or pet movement), yes. In real-world setups, accuracy varies.
