What it does
Log your meals. See the whole picture.
Say a meal, snap it, or scan a barcode. Clay, the app's AI nutritionist, logs it, cross-checks it against real food data where it can, syncs it to Apple Health, and fixes it when you say so.

However the meal comes to you
Hold the mic and say it out loud, snap the plate, or type it. Clay logs the meal as soon as it understands it, in seconds. Tap Undo, or say what to change. Every entry stays editable.
- Say it — hold the mic, talk, release to send.
- Chat or snap — Clay logs it. Tap ½, 1½ or 2× to fix a portion, or say "drop the toast".
- Scan a barcode — point the camera at a packet.
- Ask about your day — "how much protein is left?"
- Search 1.8M+ foods — packaged products included.
- Fifteen quick-adds for the foods you eat on repeat.
- Write your own for anything off the map.
- Siri, Shortcuts, Action Button — log water or a quick food, or check your day.
- Reminders that learn when you usually eat, and stop if you stop answering.
Make it yours
One day. Five ways to see it.
Pick a theme and your whole dashboard takes on its character — a quiet ceramic bowl, a printed receipt, a trading terminal, or the Day Timeline below, which lays your calories out across the hours. Same numbers, entirely different feel.
— and your Home Screen widget wears the same theme —
Nutrition
Not just calories. The whole label.
Foods that match the database carry the full label: four macros and ten micronutrients, totalled per meal and per day. Foods Clay estimates carry the four macros and are marked as estimated.
The four macros
Plus ten label micronutrients
Logged meals sync to Apple Health as dietary samples; steps and active energy read back in. Fiber tracking is one toggle away.
Rhythm
See the week, not just today.
Your week as a chart, your month as a calendar of the days you logged. Tap any day to see what you ate. Progress you can feel, never a scolding.
- Week or month, with a comparison to the last period.
- Weekly averages for calories and protein, measured against your target.
- Steps and active energy read from Apple Health, shown next to what you ate.
Water
Steady sips, counted.
Tap the droplet on your dashboard and log a cup, half a litre, a full one, or any amount you like. It carries its own daily target and writes through to Apple Health with everything else.
- One-tap amounts plus a custom field in millilitres.
- Your own target, tracked across the day.
- Syncs as dietary water to Apple Health.
Privacy
No ads. Nothing sold. No tracking across apps.
Food search sends only what you type. When you use the mic inside FitGlass, your iPhone turns speech into text on the device, and the audio never leaves it. Siri is Apple's service and follows Apple's privacy policy. Export your food log or delete your account, whenever you want.

Free today. Honest about later.
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.
