Getting started 4
What is FuelIQX?
FuelIQX is a nutrition tracker built for athletes. It turns your sport, your training and your goals into daily calorie and macro targets, adjusts them with the sessions you log, and makes logging fast — by photo, barcode, label, search or a sentence.
Which devices does it run on?
FuelIQX is available for iPhone on the App Store.
Which sports does it support?
Running, soccer, tennis, basketball, swimming, American football, gym and bodybuilding, and boxing — with positions, events and formats where they change what you need to eat. You can pick more than one sport.
Where do the targets come from?
Every target is grounded in published sports-nutrition research. The sources are listed in the app under Profile → Sources & Citations, so anyone can check them.
Logging food 4
How do I log a meal?
Tap the + button. From there you can scan a meal photo, scan a barcode or nutrition label, search the food database — including popular restaurants and fast food — or describe what you ate in your own words.
Are the calorie numbers exact?
No. AI photo estimates and database values are estimates meant for tracking trends over time, not exact measurements. For the most accurate numbers, scan a barcode or label, or adjust the portion after logging.
Where does the food data come from?
Barcode and search lookups use public food databases — Open Food Facts and USDA FoodData Central. Photo and description estimates use AI vision from Anthropic's Claude. You can also build custom foods and save recipes you eat often.
A barcode wasn't recognised. What happens?
You can enter the product's nutrition from its label. Product details (never anything about you) may then be added to a shared catalogue so the next person to scan it gets a result.
Apple Health 3
What does FuelIQX read from Apple Health?
With your permission, Active Energy, Resting Energy, Steps and Workouts — so it can show calories burned and your net energy balance.
Does it write anything to Apple Health?
With your permission, FuelIQX saves the meals you log as dietary energy, protein, carbohydrates and fat, so your nutrition sits next to your activity. It never writes workouts or calories burned.
Is my health data uploaded anywhere?
No. Health data is read and stored only on your device. It's never uploaded to our servers, never sent to our AI provider, and never used for advertising. You can revoke access anytime in iOS Settings → Privacy & Security → Health → FuelIQX.
Training groups 3
How do groups work?
Create or join a group to share sessions, photos, video and PRs, chat, run challenges and keep a shared schedule. Groups are off until you create or join one.
Who can see what I post?
Only members of that group. Every photo and post is checked against membership when it's fetched, so a forwarded link won't work outside the group. Your meals, weight, health data and email are never put into a group. A group can be discoverable or private — the creator chooses.
How do I leave a group?
From the group's screen in the app. Because groups are shared with other people, leaving is the step that removes you — so leave your groups before deleting your account if you want to be off their member lists.
Account & data 4
Will I lose my diary if I get a new phone?
No. FuelIQX keeps a private backup of your diary (never your photos) so it comes back when you sign in on a new or reinstalled phone. You can also export a backup file yourself from Profile → Your Data → Export a backup.
How do I delete my account?
Go to Profile → Account Actions → Delete Account. This permanently erases your account, its diary, and its backup on our server.
How do I clear my data but keep using the app?
Settings → Clear all data erases everything stored on your device.
Do you sell my data or show ads?
Never. No ads, no third-party advertising or analytics SDKs, and no tracking across other apps or websites. Read the full Privacy Policy.
