A research-led, contact-free tracker — the strongest here at turning your sleep data into something to actually act on.
Best for a tracker that turns sleep data into concrete, science-led recommendations.
SleepScore comes from a research-oriented company and it shows. It tracks without contact, breaks the night into dozens of parameters, and turns that into personalised recommendations rather than just a number — the strongest mainstream tracker for telling you what to change.
How we tested: Evidence-based assessment — from public information, app-store data and independent 2026 reviews. Not based on a long hands-on trial by ONDA.
Contact-free sonar tracking through the phone speaker and microphone — a clever, well-regarded approach.

Where it leads
SleepScore comes from a research-oriented company, and it shows. It tracks without contact — using sonar through the phone speaker and microphone — breaks the night into dozens of parameters, and, crucially, turns that into personalised recommendations rather than just a number. Of the mainstream trackers here, it is the strongest at telling you what to actually change.
Where it falls short
The contact-free sonar approach is clever but still a phone-based estimate, not wearable-grade. Wind-down content is light, and the genuinely useful analysis and history sit behind the paid plan.
Who it is for
Choose SleepScore if you want a tracker that does something with the data — concrete, science-led recommendations — and you would rather not wear anything to bed. If you want the deepest raw tracking, a wearable-paired app like Pillow or AutoSleep goes further.
