Common questions, plain answers.

How do I scan a meal?
Open the app, point the camera at your plate, and tap the shutter. Cardia identifies the ingredients, estimates portions, and returns a 1–10 heart score in a few seconds.

What if Cardia gets a meal wrong?
Tap the score, then “Adjust” to correct ingredients, portions, or swap to a packaged label scan for higher accuracy.

How do I cancel my subscription?
Open the iOS Settings app, tap your name, then Subscriptions, find Cardia, and tap Cancel.
