Common questions
The scan fails or says the signal is weak. Face a window or a soft lamp with no bright light behind you, hold the phone at eye level about an arm's length away, and sit still for the 30 seconds. Glasses and hats are fine; a very dark room is not. The app extends a scan to 90 seconds on its own when the signal needs it.
How accurate is it? Heart rate and breathing are measured from the camera signal. Blood pressure is an estimate from your pulse-wave shape; entering a cuff reading in the app calibrates it to you and shows how well it tracks. Blood oxygen is experimental. Revitalize is for general wellness and is not a medical device. It does not diagnose, treat or replace a cuff, an oximeter or a clinician.
Where is my data? Face video never leaves your phone. Readings and health entries are stored on your account so they survive a new phone. See the privacy policy.
How do I export or delete my data? Profile › Settings › Export my data gives you a CSV of your readings. Profile › Settings › Delete account removes the account and everything on it immediately.
I didn't get the confirmation email. Check spam, then try signing in again in the app: it sends a fresh link.
Medication reminders don't appear. Turn on notifications for Revitalize in iOS Settings, then switch the reminder on in Medications.
If you feel unwell, contact a doctor or emergency services. Revitalize cannot assess an emergency.
