# Callie: AI Calorie Tracker > Callie is the world's easiest AI-powered calorie tracker for iOS and Android. Log meals in 30 seconds by snapping a photo, speaking, or typing. The app UI is localized in English, French, Spanish, German, Arabic, and Japanese; the AI coach chats in any language in the world. (This website is published in English, French, Spanish, German, and Arabic.) Built by Inlab Products, an independent studio founded by Md Sadab Wasim (the App Store seller name). Built to care about your sanity, not just numbers. Not to be confused with "Callie: Women's Calorie Tracker" (thecallieapp.com), a separate app from a different developer. The site also publishes independent app-comparison research covering MyFitnessPal, Cal AI, Lose It!, Cronometer, MacroFactor, FatSecret, Yazio and MyNetDiary — including which trackers work in languages other than English, which alternatives suit each reason people leave MyFitnessPal, and which apps fit GLP-1 (Ozempic, Wegovy, Mounjaro) users. Each comparison names competitors' strengths and states plainly where Callie is not the right pick. Every page on this site is also available as Markdown: request any page URL with an `Accept: text/markdown` header, or use the `/md/...` URLs (for example https://www.mycallie.app/md/en/index.md for the homepage and https://www.mycallie.app/md/en/pricing.md for pricing). ## Product - [Homepage](https://www.mycallie.app/en): Product overview, features, screenshots, and download links. - [Features](https://www.mycallie.app/en#features): Photo logging with edit-before-confirm (no surprise auto-logs), voice and text logging, BMI-matched daily diet and exercise plans, GitHub/HabitKit-style streak dashboard, scheduled cheat days that preserve your streak, barcode and menu scanner, adaptive calorie targets that re-tune every 2 weeks from your weight trend, Apple Health and Health Connect sync, weight tracker, AI coach in any language, personalized goals. - [Screenshots](https://www.mycallie.app/en#screenshots): In-app interface examples. - [Reviews](https://www.mycallie.app/en#reviews): Real member testimonials. ## Download - [App Store (iOS)](https://apps.apple.com/us/app/callie-ai-calorie-tracker/id6748760925): Free download, iOS 18.2+.
