Zero Cal
AI calorie and macro tracker
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Logging food shouldn't take longer than eating it.
Zero Cal gives you four quick ways to add a meal:
• Describe what you ate in your own words
• Take a photo and let AI estimate what's on the plate
• Scan a barcode or nutrition label
• Search more than four million foods
See the whole day
The calorie ring shows how much you have left. Protein, carbohydrate, and fat stay beside it, so you can check the numbers without digging through charts.
Leave room for real life
Your daily goal fills three quarters of the ring. The last quarter is a visible cushion for a bigger dinner or an unplanned snack. You can repeat recent meals, change portions, and follow your progress over 14 days.
Ask Zero
When you want more context, ask for a short AI read on food quality, processing, fullness, and possible blood sugar impact.
What you can do
• Log by voice, text, photo, barcode, or label
• Get calorie and macro estimates
• Edit portions and ingredients
• Set personal calorie and macro goals
• Search foods, review history, and add past meals again
• Use the app in English, Spanish, or Russian
• Choose a light or dark theme
Zero Cal tracks nutrition. It does not give medical advice. Estimates can differ from the actual food, so check the label or another reliable source when accuracy matters.
