Kayva Health
Your wearable has the numbers. Understand what they mean for you.
Kayva Health watches sleep, HRV and load against your own baseline, then puts that next to your logs, your goal and this week's load. Kessa: what changed, what may be connected, one useful next step.
Join Kayva Health · How it works
I understand myself better.
Kayva Health is for people who already wear a watch. It does not score you against a crowd. It watches sleep, HRV and load against your usual, then puts that next to what you logged, what you are aiming for, and the week you are in.
Your baseline, not a crowd
Sleep, HRV and resting heart rate against what is usual for you — last night versus your recent weeks, not a generic ring.
One Kessa why
What changed, what may be connected, one next step. Tonight, today or this week. Not a pile of scores.
Citations, not certainty
Where a source helps, Kessa shows it. Research describes general relationships. It does not prove why this reading moved for you, and it does not diagnose.
A goal that changes the next step
Race, sleep, recovery, weight, fitness, or simply understand your body. The goal shapes which signal matters and what to try next — not a new score.
This week's load
Travel, race, heavy work, family, wedding — dated, in your words. Optional on-device calendar becomes tags and dates only. Event titles never go to Kessa.
Logs that connect
Food, alcohol, water, symptoms, supplements, voice. A drink or a heavy meal can tag the day so the why is not just the watch.
Ask Kessa
Chat or a voice check-in in your own words. Kessa uses summaries, not raw audio, beside your synced wellness data when you opt in.
Family wellness, if you choose
Invite someone with a Kayva account to a daily wellness summary. Sleep, activity, mood, symptom names. Not your calendar. Not a clinical record.
Signal, interpretation, action.
Wearable signals, your baseline, real life, and your goal. Kessa supports explanations with sources where appropriate and does not pretend to diagnose.
