Advanced macro tracking that's powerful enough for pros, free for everyone.
OpenNutrition is an AI-powered free alternative to MacroFactor and MyFitnessPal backed by an extensive verified food database, lightning-fast search, and continuous diet coaching.
This is the best free iOS-based nutrition-tracking app I’ve ever used.
Reinventing what's possible in nutrition
To build the most powerful, free macro tracking app we went back to the drawing board. First, we created a first-of-its-kind AI-driven food library with broad coverage of everyday generic, prepared, branded, and restaurant foods. Then, to make tracking fast and easy, we built a lightning-fast search engine to quickly locate foods by text, photo, or barcode—pulling directly from our verified library or online sources as needed.
To help you stay on track over the long run, we integrated best-in-class paid features like weight trend tracking, daily expenditure estimates, and adaptive macro adjustments that evolve as your body changes.
The result? A food logging experience that's accurate, intuitive, and fully customized to the foods you eat. And best of all, it's completely free.

An open letter from our founder
I started OpenNutrition because controlling your diet and living a healthier life shouldn’t be complicated or exclusive. Everyone deserves the confidence that comes from having the right information at their fingertips.
We built the largest custom food database available, covering everything from homemade favorites to restaurant meals and branded groceries. It’s powered by AI so new items can be added in real time, including customizations and special requests. Our goal is to give you an unprecedented view of not only calories and macros, but also key micronutrients.
But data alone doesn’t solve everything. That’s why we paired it with a friendly iOS app, daily macro adjustments, and no forced subscriptions. By making our database freely accessible, we invite developers, researchers, and anyone passionate about nutrition to help push these tools even further.
Thank you for checking out OpenNutrition. I hope it helps you take charge of your diet, stay motivated, and discover your healthiest self.
