Camera-powered vitals for iPhone
Look at your phone. Find out how you're hooting.
What the Hoot reads your heart rate and breathing rate from a short selfie video — no straps, no wearables. Then your owl shows up to tell you how it went.
Happy hoot!How it works
From selfie to scorecard in under a minute.
- Step 1
Hold still & smile
Point your front camera at your face in good light. A short scan is all it takes.
- Step 2
Presage reads your vitals
Presage technology picks up tiny changes in your face and chest to estimate heart rate and breathing rate.
- Step 3
Toss your owl
Your results decide which owl you get — smiley, normal, or sad. Flick it across the screen and score.
- Step 4
Snap a selfie
Land a smiley owl and it perches right next to you for a selfie worth sharing.
Meet the owls
Three owls. One honest read on how you're doing.
Numbers are useful, but an owl's face says it faster. Every scan hands you an owl to throw — which one depends on you.

Questions? We've got hoots.
How can a camera measure my heart rate?
What the Hoot uses Presage technology, which analyzes subtle changes in your face and upper body in the camera feed to estimate heart rate and breathing rate — no wearable required.
What do I need to get an accurate reading?
Good, even lighting, your face clearly in frame, and staying still for the short scan. Avoid backlight and heavy movement.
Is What the Hoot a medical device?
No. What the Hoot is a wellness and fun app. It is not intended to diagnose, treat, or prevent any condition. If you have health concerns, talk to a medical professional.
