Cronometer is great for micronutrients. Forge AI is faster for macros.
Cronometer built its reputation on micronutrient tracking — vitamins, minerals, amino acids. If you're tracking for clinical or therapeutic reasons, it's one of the most thorough tools available. But for most people tracking macros to cut, bulk, or maintain, it's more complexity than they need.
Forge AI takes a different approach: AI-powered macro logging that handles restaurant meals and real-world food in under 10 seconds per meal. No database hunting, no account, and free to try during beta.

Where Cronometer wins
Cronometer tracks over 82 micronutrients — vitamins, minerals, amino acids, fatty acids. If you're working with a dietitian, managing a health condition, or following a therapeutic diet that requires precise micronutrient monitoring, Cronometer is the more thorough tool.
Its food database is also highly verified, with NCCDB and USDA data sources that are more accurate than user-submitted entries in other apps. For people who need clinical-level precision, that matters.
Where Forge AI wins
Speed and simplicity. Forge AI handles the meals that break every database-based tracker: restaurant orders, homemade dishes, mixed meals, and anything you'd describe rather than search for. You type what you ate and the AI estimates macros instantly.
Forge AI is also free to try during beta with no account required — Cronometer's free tier is limited, and premium features like Gold require a paid subscription. And Forge AI includes an AI workout builder that Cronometer doesn't have at all.
Which one is right for you?
Choose Cronometer if you need detailed micronutrient tracking for health or clinical reasons. Choose Forge AI if you want fast, AI-powered macro tracking for fitness goals — cutting, bulking, or maintenance — without paying for features you don't need.
Frequently asked questions
Is Forge AI free compared to Cronometer?
Yes. Forge AI is free to try during beta. Cronometer's premium tier (Cronometer Gold) costs $9.99/month for features like trend analysis and meal planning.
Does Forge AI track micronutrients like Cronometer?
No. Forge AI focuses on macros — protein, carbs, fat, and calories. If micronutrient tracking is your primary need, Cronometer is the better tool.
How is AI logging different from Cronometer's database?
Cronometer requires you to search a food database and find the closest match. Forge AI lets you describe a meal in natural language — "chicken stir-fry with rice and broccoli" — and the AI estimates the macros instantly. This is much faster for restaurant meals and home cooking.
Do I need to create an account to use Forge AI?
No. Forge AI requires no sign-up. Open the app and start tracking immediately.
