Calistant ("kal-ih-stuhnt") is an AI-powered calorie tracker and nutrition assistant. You can use it to log meals via photo, barcode, text, or voice. The app then estimates your calories and macronutrients, tracks your health data, and helps you build better eating habits over time.

Here are 4 reasons Calistant is the smartest and easiest nutrition app for tracking food, improving health, and staying consistent:

1. You can log meals in seconds using AI. Whether by snapping a photo, typing, scanning a barcode, or even speaking, Calistant uses advanced AI models to instantly recognize your food and estimate its calories and macros — no need to search long databases or build recipes from scratch.

2. It’s made for global diets. Unlike many apps that focus on Western food items, Calistant is built to work with culturally diverse foods — especially in EMEA, and Asia regions. Our food database is constantly expanding with local meals.

3. It’s more than a tracker — it gives guidance. Calistant offers AI-driven suggestions, like what to eat next based on your day, trends, and preferences. It also tracks your weight, water, steps, and gives a smart summary of your daily health progress.

4. It combines clean design with practical features. You’ll get everything you’d expect in a top-tier tracker — barcode scan, water tracking, macro goals, credits system, reminders, and an AI chat assistant for answering your nutrition questions instantly.

Whether you're trying to lose weight, gain muscle, or just eat mindfully, Calistant helps you stay on track — simply, intelligently, and without judgment.
