AI Photo Calorie Tracker App

Snap a photo of food; a vision model estimates calories and macros. Sold via subscription, marketed with influencers.

In plain English

Point a phone at a plate, and this app estimates how much energy is in the food, plus the protein, fat, and carbohydrate. People who watch what they eat pay a subscription, because adding that up by hand is slow. The AI does the looking and the estimating, and it also takes payment. Zach Yadegari and Henry Langmack still do a fair share of the business themselves. They work with fitness creators who show the app in videos, keep shaping the product, and handle the parts that are more than a photo guess.

Overview

Snap a photo of food; a vision model estimates calories and macros. Sold via subscription, marketed with influencers. Operator: Zach Yadegari (with Henry Langmack).

Realistic income

Reported: $28K first month; $30M revenue in 2025; $5.7M in Jan 2026 (founder, reported by TechCrunch/CNBC). This is one operator’s result and doesn’t predict yours.

Risks

Photo estimates miss mixed plates, sauces and portions. Wrong numbers show up in App Store reviews fast.
Nutrition apps face strict store and health-claim rules, and a bad estimate is more than a user-interface bug.
Growth here depends on influencers and ads, and large meal-log apps already occupy the category.
