Tracking macros gets old when you can't tell if the effort changes how you feel. fuelOS takes a different angle—it links nutrition data to energy levels and mood through daily check-ins.
Snap a photo of your meal. The AI identifies food and estimates portions. It calculates calories. Breaks down protein, carbs, and fat in real time.
Numbers aren't the endpoint here. fuelOS asks how you're feeling throughout the day. Energy good? Focus sharp? That correlation between what you ate and how you actually function—that's the center of it. You might hit your 2,800 calorie target and 160g of protein but still feel sluggish. Check-ins help surface those patterns.
Custom goals? You can set them for macros and calories. Photo analysis handles single-shot meal logging. No manual entry unless you want it.
Here's the catch—iOS only right now. It runs on a freemium model (basic tracking won't cost you anything). Users who've tried Yazio and MyFitnessPal mention this as a step up for understanding the "why" behind energy crashes.
A competitive athlete tracking performance metrics would find value here. So would someone trying to figure out why afternoon focus tanks after certain lunches. No API access or developer integrations though. It's built for personal use—not for plugging into other systems or building custom workflows around nutrition data.
