What is Kairo and how do I get started?

Kairo records what you eat and sets it against your daily goal. A meal gets into the app in four ways: as a photo, as a description by text or voice, through the barcode on a package, or through a photo of a restaurant menu. For every meal Kairo shows calories, protein, carbohydrates and fat.

On top of that there is the Body Map, which shows how your nutrition supports different body systems, groups with friends, a streak, widgets for the Home Screen and Lock Screen, an Apple Watch app and Apple Health integration.

From your setup answers Kairo calculates your basal metabolic rate (BMR) with the Mifflin-St Jeor equation, and from that and your activity level your total daily energy expenditure (TDEE). Depending on your goal (lose weight, maintain, build muscle, gain weight), that gives your calorie goal and macro goals.

You can change your goals later in your profile under "My Goals".

The download is free of charge. Without a subscription every account has three AI analyses; barcode lookups are unlimited. From the fourth AI analysis on you need a subscription. Details: Scans without a subscription and Prices, plans and the free trial.

The numbers are AI estimates and can differ from the actual nutritional values. We measured how close they get and published the results: How accurate is Kairo?. Kairo does not replace professional dietary advice or a medical diagnosis.
