For POTS & dysautonomia

Lie down.
Stand up.
Know.

The at-home standing heart-rate test, finally repeatable. Orsa times the protocol, catches your heart rate at 1, 3, 5 and 10 minutes, and turns scattered bad days into a chart your cardiologist can use.

Lying down

Rest until your heart settles

Orsa times the lying-down phase and holds your baseline. The bear rests with you, and the countdown runs inside its dream.

Standing

Stand, and let it watch

Heart rate lands at 1, 3, 5 and 10 minutes, live from your Apple Watch through HealthKit, or typed in when it asks. Every reading is drawn as it happens.

The picture

Your rise, against the line

Each test is drawn against your own baseline and the commonly cited +30 bpm reference (+40 for teens). No verdicts, no diagnosis. Just your numbers, made legible.

The proof

Repeat it on good days and bad

One test is an anecdote. Twenty are a pattern. The trend hangs in the bear's museum, and it is the difference between “I feel worse when…” and a chart.

Between the tests

Real life, gently drawn

The days between tests are the data your doctor never sees. Orsa makes them two taps: a symptom and its severity, a flare and its trigger, a glass of water, a salt stick.

On your phone

Every test, entry and export lives on the device in your pocket. There is no server to trust.

No account

Nothing to sign up for, nothing to leak. Open the app and start.

HealthKit, read-only

Heart rate is read only during a test, only with your permission, and never transmitted.

No analytics

No trackers, no third parties, no quiet phone-home. The whole policy fits on one page.

Orsa is not a medical device and does not diagnose, treat or rule out any condition. The stand test is a self-tracking aid, not a tilt-table test. If you faint, have chest pain or feel unwell, seek medical care.

Tomorrow morning,
run your first test
