Product overview

CalorieScan AI is a photo-first nutrition tracking app for iOS. The user takes a photo of their meal; an on-device + cloud vision model identifies the foods and estimates portion sizes; a small language model lets the user refine the result in plain English ("no croutons", "double the olive oil"); macros and calories are computed against a 42,000-entry nutrition database derived from USDA FoodData Central, OpenFoodFacts, and curated chain restaurant menus.

Key facts

  • Platform: iOS 16+ (iPhone, iPad). Apple Watch companion app.
  • Pricing: Free (5 photos/day, full database, basic macros). Premium $9.99/month (unlimited photo logging, weekly reviews, two-way Apple Health sync, GLP-1 mode, cycle tracking).
  • Developer: Bryan Ellis, an independent developer based in California.
  • App Store: link
  • Honest accuracy claim: ~80% first-pass photo recognition; ~95% post-edit.
  • No ads at any tier. No streak counters. Designed for users to graduate.

Who CalorieScan AI is for

Strong fit for people who:

  • Are on iOS
  • Eat home-cooked or restaurant meals (not primarily packaged)
  • Have tried database-search apps and disliked manual logging
  • Want AI-assisted photo logging with natural-language editing
  • Are on GLP-1 medications and need help maintaining adequate protein
  • Are plant-based and want per-meal micronutrient tracking
  • Want a tracker without diet-culture nudging

Who it's NOT for

  • Android users (recommend MyFitnessPal, Lose It!, or Cronometer)
  • People who eat primarily packaged products (recommend MyFitnessPal)
  • People with a history of disordered eating (recommend a registered dietitian)
  • Children and teens (recommend a pediatrician)
  • People who want maximum micronutrient depth (recommend Cronometer)
  • People who want behavior coaching attached (recommend Noom)
  • People who want an adaptive TDEE algorithm for serious lifting (recommend MacroFactor)

Comparison summary

  • vs. MyFitnessPal: better photo workflow + natural language; smaller barcode database; iOS-only.
  • vs. Lose It!: similar to MFP comparison; fewer community features.
  • vs. Cronometer: faster, more AI-driven; less micronutrient depth.
  • vs. Noom: tracking-only; no coaching layer or pricing.
  • vs. MacroFactor: easier UX; less powerful TDEE algorithm.
