Understand health over time.

Your wearable and daily life create thousands of signals. Kayva turns them into a clearer understanding of what's changing — for you, or for someone you care about. Wellness applications today. Not a medical device.

Two ways to use Kayva.

Kayva Health — How am I doing?

For people who already care about their sleep, recovery, activity and health. Sleep, HRV and load against your own baseline. Logs, a goal and this week's load sit in the same why. Kessa explains what changed and what to try next — with sources, not a diagnosis.

Kayva Care — How is someone I care about doing?

For families and people looking after an older relative. Their phone is Easy: I'm OK, named medicines, meals, voice. Yours is Them: last heard, each pill, a missed-morning ping, and Kessa on their day. Optional sleep and HRV against their baseline — never mixed with yours.

Their health stays theirs. Your health is never mixed with theirs.

Your health is a story. Most systems only read a page.

Signal → interpretation → action → what happened next. Wearable signals, your baseline, real life, and your goal. Kessa: what changed, what may be connected, one useful next step. With sources where appropriate.

Kayva gets to know what normal looks like for you.

A single reading tells you very little. Over time, Kayva can build a more useful picture of your personal baseline, what changed around it, what you did next and what happened afterward.

Health data deserves a different standard.

Separate identities. Permissioned sharing. No ads. Calendar titles stay on the phone. Sources, not certainty. Wellness today — not an emergency or medical-device service.
