FitGlass: AI Calorie Tracker
The gentle AI nutritionist
Free · Designed for iPad. Not verified for macOS.
Log a meal in one sentence, a photo or a barcode. Clay finds the foods, and your bowl fills as you eat. No ads, no social feed, no food streaks.
FitGlass is a calm, beautifully crafted calorie and nutrition tracker for iPhone. Say a meal out loud, snap it, or type it in a sentence — Clay, the app's AI nutritionist, identifies the foods, portions, calories, and macros, so you skip the searching and tapping.
Most trackers feel like spreadsheets with ads. FitGlass feels like a warm kitchen. Your day lives in a hand-thrown ceramic bowl that fills as you eat, in one of five home-screen looks you choose. No ads. No social feed. No guilt.
FIVE WAYS TO LOG
• Log with Clay — type "two rotis, dal, and a bowl of curd", tap the mic and say it, or send a photo. Clay identifies each food with calories, protein, carbs, fat, and fiber, and logs it as soon as it understands. Tap Undo, or just say what to change: "make the rice a cup", "drop the toast".
• Scan a barcode — point the camera at a packaged product and it lands in your day.
• Search — 1.8M+ foods, packaged products included, with real serving sizes.
• Quick add — 15 one-tap staples, from chicken and oats to dal, paneer, and roti.
• Write it yourself — full manual entry when you know the numbers.
ASK CLAY, TOO
"How much protein is left?" "How have I been eating this week?" "What should I have for dinner?" Clay answers from your own log, and takes your dietary preferences into account.
SIRI AND SHORTCUTS
"Log water in FitGlass." "How am I doing in FitGlass?" Log water or a quick food, check your day, or start a meal — from Siri, the Shortcuts app, or the Action Button.
A HOME SCREEN WITH A FACE
Today's calories live in a ceramic bowl that fills as you eat. Choose from five themes — Bowl, Dot Matrix, Receipt Ledger, Day Timeline, and Terminal Block — and your Home Screen widgets wear the same look. On iOS 26, the controls float on glass. Prefer the old look? Switch to Classic any time.
NUTRITION, NOT CLUTTER
Protein, carbs, and fat by default; fiber as a first-class macro with a target set to dietary-guideline standards. One tap opens the day's nutrition label, with 10 micronutrients from database-matched foods — sugar, saturated fat, sodium, cholesterol, potassium, calcium, iron, and vitamins A, C, and D.
WATER, TOO
Press and hold the water button to log a glass, or open the water page for more. Your goal is set from your body and how much you move, and it flows to Apple Health with everything else.
YOUR RHYTHM
See your week Monday to Sunday, or a whole month as a calendar — the days you logged, the days you did not, and how it compares with the last one. Tap any day for its calories, macros, and full log. A rhythm you can see, never a judgment.
REMINDERS THAT LEARN
Meal reminders settle on the times you actually eat, stay quiet once you have logged, and stop asking if you stop answering.
WORKS WITH APPLE HEALTH
Your activity flows in, so "calories left" respects your movement. Your logged nutrition and water flow out.
PRIVATE BY DESIGN
No ads. Sign in with Apple. The in-app microphone transcribes on your device. Export your food log as a file, and delete your account and data entirely, any time, right in the app.
A NOTE ON THE AI
Clay gives estimates, cross-checked against real USDA data where it can match a food. Everything Clay logs stays editable — change a portion with one tap, correct it in words, or undo it entirely. Meal ideas take your dietary preferences into account, so check them yourself before you cook.
Gentle tracking, not guilt. Set your bowl.

A new look for iOS 26
• The tab bar, Clay's bar and the main buttons now use Liquid Glass. If you prefer the old look, choose Classic in You → App.
• In the Bowl view, today's food fills a glass bowl.
• A new app icon, with dark, clear and tinted versions.
• The Home Screen widget is easier to read in the Clear and Tinted styles.
Better logging
• Clay's message box clears after you send, and the Return key sends.
• If voice logging is off in iOS Settings, FitGlass now shows you how to turn it back on.
• Account emails now come from fitglass.app, so they are less likely to go to spam.
• Bug fixes.
