Calvi: AI Calorie Tracker
Log meals by text or photo
Free · In‑App Purchases
New: Apple Health. Workouts, steps and weight from your Apple Watch land in your diary by themselves, and in the evening Nora reviews your day.
Calvi is a food diary where you never type calories by hand.
Write the way you speak: "two eggs and toast with butter", "a bowl of borscht", "300 ml of water", "ran 30 minutes". Nora, the built-in AI assistant, reads the sentence, recognises the dish, takes the portion weight into account and logs calories, protein, fat and carbs herself. If the weight is missing, she asks once and offers amounts you pick with one tap. No tables, no searching a database, no calculator.
A PHOTO INSTEAD OF WORDS
Snap your plate and Nora tells you what is on it and what it adds up to. The photo lives only as long as the analysis takes: it is never stored and never reaches our database.
ONE DIARY FOR THE WHOLE DAY
• Calories, protein, fat and carbs for every meal, counted by Nora
• Water
• Weight and body measurements
• Workouts: burned calories are subtracted from what you ate, so a training day gives you room
• Medications with reminders
A NORM THAT IS YOURS
The daily norm comes from the Mifflin-St Jeor formula: height, weight, age and activity. You choose the goal and the pace, and the app says plainly when you will get there and when the pace is too aggressive to hold. Days inside your norm turn green, and the streak counts them.
NORA REMEMBERS
Say "I don't eat pork" once and never repeat it. Allergens are checked against what a dish is made of, not its name, so peanuts hidden in a sauce do not slip through.
YOUR OWN DISHES
Log your homemade borscht once and it counts the same way next time. Your dishes stay yours and never change the shared reference for anyone else.
ANALYTICS WITHOUT DECORATION
Weeks and months as charts: calories, weight, macros, measurements. You see the trend instead of one bad day.
FREE AND PRO
The diary, analytics, water, workouts, measurements and medications are free, with no ads and no time limit. Nora is free too, within a monthly allowance of tokens: a message costs one, a photo two. Calvi Pro removes the allowance: unlimited conversations, photos, weekly reviews and recipe ideas. Pro is a monthly or yearly subscription that renews automatically until cancelled; cancel anytime in your App Store subscription settings. Buying Pro requires signing in, so the subscription follows you to a new phone.
WORKS WITHOUT AN ACCOUNT
The app is ready from the first second, with no email and no password. Sign in with Apple or Google does two things: it brings your entries back on a new phone and it ties Pro to you rather than to a device.
HONEST ABOUT THE NUMBERS
Calorie values are estimates: from the label for packaged food, averages for dishes. Calvi is a logging tool, not a medical device and not a doctor. Decisions about your health stay with you and your physician.
