Fettle is a nutrition planning app that calculates your personalized macro targets, helps you choose meals that fit those targets, and adapts your plan weekly based on real progress. Instead of tracking first and figuring out what it means later, Fettle guides decisions upfront - so you know what to eat, what to buy, and how to adjust without the guesswork.

How does Fettle work differently from traditional tracking apps?

Traditional apps focus on logging what you've already eaten. Fettle focuses on planning what you should eat - calculating targets using evidence-based formulas, matching meals to those targets, and generating shopping lists automatically. Then it adapts weekly based on your progress, catching plateaus and metabolic changes so you're not constantly manually adjusting everything yourself.

Who should use Fettle?

Fettle is built for people who want real nutrition guidance without rigid meal plans or obsessive tracking. If you're tired of apps that make you log everything then leave you to figure out what it all means, or if you've hit plateaus and don't know how to adjust - Fettle gives you a practical system that adapts as your body and life change.
