What our members say
“VitalSign flagged an irregular heart rhythm at 11 PM. I showed the AFib report to my cardiologist the next morning — he confirmed it and adjusted my meds. Probably caught it 6 months earlier than I would have.”

“I monitor my 78-year-old dad remotely through the Care plan. I see his BP, SpO2, and sleep every morning. The morning he had a low SpO2 reading, the alert woke me up before he even knew something was wrong.”

“The sleep score changed how I train. I used to push through bad-sleep days and wonder why my runs felt terrible. Now I dial back on score-under-70 days and hit PRs on the high-recovery ones. Game changer.”
