Calorist | iOS App AI Calorie Tracker with Laravel Admin Panel

Calorist iOS is a native iOS application, written in Swift with SwiftUI, for tracking calories and nutrition with AI-powered food logging. Built for the health & fitness market, it combines a polished native mobile UI with a production-ready Laravel admin panel backend, Firebase Remote Config, and Google Gemini AI.

The app is organized around five main tabs — Home, History, a center Scan button, Insights, and Profile — giving users a complete workflow from logging a meal to understanding their trends. Snap a photo of a plate, scan a barcode, or just describe a meal by voice — the AI returns calories and macros (protein, carbs, fat) in seconds. Daily goals, a calorie ring, water tracking, and an AI nutrition coach keep users on track.

Key Value Propositions

• For End Users: Log food three ways — snap a photo, scan a barcode, or describe a meal by voice or text; get instant calories & macros; track daily goals with a calorie ring and water intake; review your full meal history; and see personalized trends and AI coach tips in Insights.
• For Health-Conscious Users: Set personalized daily calorie and macro targets, track progress against goals, browse a searchable food history, and get an AI-generated weekly summary of your nutrition patterns.
• For App Owners / Developers: A complete, monetizable iOS product with subscription support, multiple color themes, onboarding layouts, paywall variants, push notifications, ads, analytics, and remote configuration — all without rebuilding the AI food-logging pipeline from scratch.

AI Usage Disclosure

This item uses AI as a core feature. The app’s main functionality relies on third-party generative AI services to turn what you eat into nutrition data:

• Meal photo analysis: powered by Google Gemini (Gemini 2.5 Flash vision model) — detects foods in a photo and estimates calories and macros.
• “Describe a meal” (voice & text) logging: powered by Google Gemini (Gemini 2.5 Flash-Lite) — parses a natural-language meal description into structured foods and nutrition.
• Nutrition insights & AI coach cards: powered by Google Gemini — generates personalized tips from your recent logs.

All calorie estimates, macro breakdowns, and coach tips created inside the app are AI-generated content produced by these services and are approximate — they are not medical or dietary advice. Barcode lookups are not AI: nutrition for packaged products comes from the public OpenFoodFacts database. Voice dictation uses Apple’s on-device Speech framework, so the audio itself never leaves the phone — only the resulting text is sent for parsing. The application source code itself was written and is maintained by our team. To use the AI features, you must create your own Google Gemini (Google AI Studio) account and supply your own API key (see the Disclaimer below).

Disclaimer

This app is built to work with a Laravel admin panel backend (database, auth, API, and AI proxy) and the following third-party services: Google Gemini (AI food analysis & insights), Firebase (Auth, Remote Config, Analytics, Crashlytics, APNs), RevenueCat (subscriptions), OneSignal (push), and optional AdMob ads. Barcode lookups use the public OpenFoodFacts catalog. These backend services are not included in the purchase — you will need to create your own accounts, configure API keys, and manage hosting and AI usage costs yourself. Basic familiarity with Xcode, Firebase, Laravel, and App Store Connect is recommended before launching.
