fuelOS

Everything you put in your body. One place.

Food. Supplements. How you feel. Logged in the order you live them.

fuelOS is built for people who take what goes in seriously. Anyone can pick it up.

CAPTURE IN ONE GESTURE

Snap a photo. Speak. Scan a barcode. The card appears and fills in as it reads, section by section. No forms.

THE STACK

Your supplements, vitamins, powders, and the rest of your routine, in one view.

Point the camera at the bottle to add it. Log a dose in one tap from your Home Screen. Set reminders, then log, skip, or snooze.

DOWN TO THE COMPOUND

Macros and micronutrients, estimated by AI from the photo. fuelOS also estimates bioactive compounds in your food, like curcumin and beta-glucans. The detail you usually have to hunt for is already on the card.

Estimates carry a ~, so a guess never reads like a scanned label.

HOW YOU FEEL

A daily check-in for energy, mood, and focus. Logged beside what you ate that day.

CARRY IT EVERYWHERE

Quick-log from the Home Screen widget or with Siri and Shortcuts. Meals and macros sync to Apple Health.

Turn a streak or a strong day into a clean card, stating one true fact about your own data.

FREE TO START

A few free AI meal scans a day. Re-logging a past meal is always free.
