ONDA: Live Coherence & HRV

ONDA - Know Your Body's Normal

Most health apps hand you numbers. ONDA learns what's normal for YOU — then tells you when something changes.

Your resting pulse, heart-rate variability and breathing all live inside a personal range. ONDA reads two weeks of your Apple Watch history and draws that range — your baseline. Then it watches quietly, and when your body drifts outside its normal corridor, it lets you know. Not every day. Only when there's something to say.

YOUR BASELINE, OPENED IN A DAY
Connect your Apple Watch and ONDA opens your last two weeks of Health — resting pulse, HRV, breathing and more — in one calm view. Your history was already there. Now you can read it.

A QUIET SIGNAL WHEN IT MATTERS
When last night sat outside your normal range, ONDA sends one gentle nudge — never a diagnosis, never a scare. "Your resting pulse was higher than usual — anything happen?" You note what was going on: late coffee, stress, poor sleep. Over time, you see what actually moves your body.

TWO TIMELINES, ONE PICTURE
Your numbers on one line, your life on the other. Log a moment by text or voice — it sits right next to the data from that day. The connections surface on their own.

BREATHE BACK INTO RANGE
Off your baseline? ONDA offers a short practice to help your body settle — resonance-frequency breathing, slow paced breath, interoceptive awareness. Watch your pulse respond live, from your iPhone camera or Apple Watch. Feedback during, not a score after.

THE SCIENCE, NOT JUST THE VIBE
Every signal and practice comes with its physiology — the mechanism, the pathway, why it shifts you toward parasympathetic. We name what's measured and don't dress up what isn't. No invented scores, no fake precision.

EVERYTHING STAYS ON YOUR DEVICE
Your Health data stays in HealthKit. Your baseline is drawn on-device. Your journal — text, voice — never leaves your phone. Export a clean PDF for your doctor with one tap; even that is built locally and shared by you, not us. Nothing is sold or sent to third parties.

FREE, FOREVER
Three core practices and your baseline are free, no account. Full access — all practices, deeper analytics, the full 8-level progression — is $14.99/month or $64.99/year, with a free trial.
