Proof Network #3 · SL Watch

Medical-grade ECG,
on your wrist.

A 125 Hz ECG sensor and an on-device AI screen for abnormal heart-rhythm patterns every 10 seconds — built on a 4-year clinical study with AUROC 0.88.

Wellness device. Not for diagnosis. Medical-device functions will be offered after KFDA clearance.
