Nutrition, logged

FitGlass AI calorie tracker for iPhone

Say a meal, snap it, or scan a barcode. Clay logs it, and fixes it when you say so.

Download on the App Store →

Free on the App Store. Designed for iPhone, iOS 17 or later.

Type "two rotis and dal", say it into the mic, or point your camera at the plate. Clay, the app's AI nutritionist, logs the calories, protein, carbs, fat and fiber, and syncs it to Apple Health. Wrong portion? Say "make the rice a cup".

What makes FitGlass different

Log it your way

Tell Clay out loud, snap the plate, or type "two rotis and dal". Scan a barcode, search 1.8M+ foods, tap a quick-add, or write it in yourself. Or tell Siri: "Log water in FitGlass."

The person behind it

Why I built it

I've started my fitness journey more times than I can count. A week was my record, and I set that record while paying for a subscription. By the time I'd found the right rice I'd lost interest in logging the dal. I was trying to fix my own week-one problem, which is that I'd never once made it to week two.

FitGlass is free today. Clay's AI costs real money every time you use it, so AI logging will carry a price later to cover that. Nothing else is decided.
