Built different

A nutrition app that finally
understands you.

Most calorie apps are spreadsheets dressed up. Calo. is a closed-loop system: it reads your body, learns your habits, and adapts your nutrition every single day.

AI Food Scanner

Point your camera at any meal. Calo. identifies ingredients, estimates portions, and pulls USDA-verified macros in under three seconds. No barcode hunting. No dropdown menus. No guessing.

Biometric Intelligence

15+ live signals from Apple Health, Whoop, Garmin and Oura — HRV, sleep, recovery, strain — feed directly into your nutrition model.

Adaptive Targets

No static numbers. Your daily calorie and macro targets shift based on yesterday's training, sleep quality, and recovery.

AI Coach

A personal nutrition coach trained on your patterns. Ask anything; get specific, contextual answers that know what you ate yesterday.

Meal Planning

Weekly plans built around your cuisine, allergies, and schedule. Shopping lists generated. Macros guaranteed.

Recovery Nutrition

Eat for tomorrow's session. Macros calibrated to yesterday's strain so you train hard and stay hungry.

How it works

Three taps to a smarter plate.

Onboarding takes ninety seconds. After that, Calo. handles the rest.

Connect

Link Apple Health and your wearable. Calo. immediately starts reading 15+ biometric signals — sleep, HRV, strain, recovery — and builds a baseline of your body.

Eat

Scan meals with your camera. Calo.'s vision model identifies ingredients and matches them to USDA-verified nutrition data — no manual logging, no barcode hunts.

Adapt

Every morning, your targets recalibrate based on what your body actually did. Hard session yesterday? More carbs today. Bad sleep? Higher protein, gentler deficit.

The science

Not another
calorie counter.

Calo. uses Google Gemini's vision model for food identification, validates results against the USDA FoodData Central database, and applies a proprietary biometric model that fuses HRV, sleep, and strain into a daily energy availability score.

  • Local-first architecture. Your food logs, weight, and goals stay on your device — never on our servers.
  • HealthKit-compliant. Health data is never used for advertising, never sold, never shared.
  • USDA-validated nutrition. Every estimate cross-checked against the U.S. government's gold-standard food database.

Loved by athletes

Built with the people
who can't afford to guess.

The first nutrition app that actually understands recovery. My carb targets shift with my Whoop strain — finally, an app that respects how my body actually works.

Replaced my dietitian. The AI Coach knows what I ate yesterday and what my heart rate did last night, and gives me answers no app has ever come close to.

I've used MyFitnessPal, Cronometer, MacroFactor — none of them adapt. Calo. adjusts my targets every morning. It's the closest thing to a real coach in my pocket.
