What's New in fuelOS

1.8.4

July 28, 2026

APPLE HEALTH SYNC (PRO) The Health categories you pick sync to your private fuelOS cloud, continuously, from the moment you turn it on. Your AI can read it. Ask about a run, a rough night's sleep, or how your training week actually went. You choose the categories. The sensitive ones — cycle and reproductive health, mind and mood, workout routes — are asked for separately, or not at all. Download the whole archive whenever you want. Delete it and see the receipt. ASK YOUR DATA Connect fuelOS to Claude or ChatGPT and ask about your meals, trends, goals, and stack in plain language. Read-only. Settings → Integrations. YOUR DATA STAYS PUT Reinstalling no longer costs you your stack, your meals, or your settings. Everything restores now, including supplement details and label scans that used to drop silently. FOOD DATA Barcode scans read our own food database instead of a third-party API. Faster lookups, and micronutrient amounts are correct. LOGGING Say "Log a meal" to Siri, or run it from Shortcuts and Spotlight. Type an amount and it's read as what you took, not what's in a serving. Say when you ate — "at 8 this morning" lands at the right time. A protein shake no longer gets logged as creatine. SHARE New protein streak card: your run as a calendar, built from your own data. Share cards render correctly again. FASTER The home energy card runs at 120Hz. Smoother scrolling and chart animations on long histories. FIXED A crash at launch. Meal photos stay crisp and tappable. The draft card stays above the keyboard and the dock. The last meal clears the buttons instead of hiding behind them. Supplement chips get short names again, and the stack rail shows when unlogged items are scrolled out of view.

Based off Reddit post

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

1st day using it and love it!

I love it so much

Very accurate, very efficient, makes my life easier

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!
