Design

Quietly recording. Less to think about.

A small sensor beneath your mattress, built to stay out of sight—with less to manage each day.

Nightly records

Heart rate and breathing, second by second.

STILL records heart rate and breathing every second, along with movement through the night. Nightly readings are included for free; After Light Plus adds second-by-second curves and exports.

Before you buy

A fit for your bed. And your routine.

Will STILL work with my bed?

STILL works with most mattress types and thicknesses, with a suitable bed base and placement. It isn’t suitable for waterbeds, water bladders, air mattresses, or box springs. Check your bed type before ordering.

Check your bed

Do we need two for a shared bed?

Each person uses their own STILL, placed on their side of the bed. If you both want to understand your sleep, choose the Duo set.

What do I need to get started?

You’ll need 2.4 GHz Wi-Fi, a USB-C power adapter (not included), and the After Light app.

For iPhone and Android. Download availability, supported models and minimum operating system versions to be announced.

Do I need a subscription?

No. The app has a free plan, with Plus as an option. When the included period ends, you return to the free plan and keep your records, with no automatic renewal or charge.
