New: The Stack. Track your supplements and powders right alongside your meals.
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.
fuelOS PRO
Unlimited logging. Micronutrient estimates. The analytics dashboard. Apple Health. Export your data, anytime.
Take what goes in seriously. Start here.

I ended up downloading this app off of a Reddit post .once I downloaded the app and start scanning my food. I noticed that the AI and the tracking of this particular app actually tracked the ingredients of the type of food that you eat not necessarily go based off of the database which is found in many other apps, the app is itself is smooth is clean and I’m still testing at the moment but right now at the time. I’m definitely a big fan of it
Makes nutrition tracking so much easier

Great nutrition tracking app with intuitive UI design and features that allow you to tailor it to your specific goals — makes it very quick and easy to keep track of calories and macros
Best AI calorie tracker I’ve used!!!

Tracking nutrition has never felt this seamless. It’s genuinely helped me on my fat loss journey.I’ve tried a bunch of apps, Yazio, Lifesum, Cal AI, SnapCalorie, MyFitnessPal……. and this one is easily the best.The UI/UX is beautiful and minimalist, and the AI is more accurate than the other apps. Plus, it’s free to use for 3 meals a day, which is enough for me!
Great app
Let us have our pictures
I’ve really enjoyed using this app so far! it makes health and wellness feel simple, supportive, and realistic
fuelOS now tracks more than food.
Everything you put in your body. In one place.
THE STACK
Food was only half of it. Now the supplements, powders, and everything else you take live in the same place, on the same timeline.
Add an item by pointing your camera at it. Log a dose in one tap from your Home Screen, or by voice with Siri. Set a quiet reminder so you actually take it.
ALSO NEW
Bioactive compounds. Meal analysis now estimates compounds in your food, like curcumin and beta-glucans.
Shareable cards. Turn a streak or a strong day into a clean card built from your own data.
Recent Meals. One tap to log again, no fresh scan needed.
FASTER
Meal cards appear right away and fill in section by section.
The camera is rebuilt. Scanning is steadier, and the washed-out preview is gone.
A smoother feed while logging. Faster scrolling through long histories.
FREE TIER
Re-logging, copying, moving, and splitting a meal no longer count against your free AI scans. Only fresh analyses do.
FIXED
Meals logged after midnight land on the right day. Voice capture is steadier. Supplement chips reset cleanly each day.
Removed the attribution SDK (Tenjin) that linked the App Tracking Transparency framework, so the app no longer uses ATT.
Removed collection of the advertising identifier (IDFA), along with the SKAdNetwork and advertising-attribution configuration.
Removed the NSUserTrackingUsageDescription key, since the app no longer requests tracking authorization.
Version 1.7.12
