About Fettle
Nutrition that adapts to your Life.
Fettle was created to make healthy eating simple, personalised, and sustainable — without spreadsheets, guesswork, or overwhelming diets. Our nutrition engine updates your calories and macros every week, based on your progress, real habits, and real life.
Why Fettle Exists
We didn’t need another tracking app. We needed a better system.
Most nutrition apps ask you to track everything first — then leave you to work out what to eat, what fits, and what to change. That approach assumes time, confidence, and constant decision-making — things most people don’t have consistently.
Fettle was made to flip that model
We work selectively with partners who share our commitment to:
Calculates how much you need to eat.
Shows what actually fits your targets
Turn meals into a ready-to-shop plan
Adapts weekly as your body and habits change
Built for real people, living real lives
Fettle was created for busy parents, professionals, students and anyone trying to stay healthy without the stress. No strict diets. No spreadsheets. No guesswork - just simple, personalised nutrition that adapts to your life. Our mission is to make healthy eating effortless, sustainable, and genuinely enjoyable.
Our values
Created by nutritionists, powered by real science
Weekly Personalisation
Most nutrition apps give you a static calorie target and expect you to manage the rest. Fettle works differently. Every 7 days, Fettle reviews your progress and automatically updates your calorie and macro targets so your plan stays aligned with your body as it changes.
What this means in practice:
Calories adjust as you lost fat or gain muscle
Plateaus and metabolic adaptation are accounted for
No manual math or guesswork
Designed for sustainable, long-term progress
Your body changes. Your nutrition should too.
