How it works

From “what I ate” to real macros in three steps

No food-search dropdowns, no manual macro math — describe your meal your way and let Calzentra do the lookup.

Step 1

Type it, snap it, or say it

Describe your meal in plain language — "a chicken sandwich and a side salad" — take a photo of your plate, or record a quick voice note. All three work equally well, and a voice note can cover your workout, water and sleep in the same breath.

Step 2

AI extracts the items

AI parses typed text, reads photos of your plate, and transcribes voice notes — each turns your input into a structured list of foods and quantities.

Step 3

Real macros, verified

The resolve engine matches every item against IFCT, USDA and Open Food Facts — AI only estimates when nothing else matches, and you're always told which.

The nutrition engine + resolve engine

Two engines. One number you can trust.

Most AI food loggers let a language model invent your calories. Calzentra splits the job in two: a resolve engine that works out exactly which food you mean, and a nutrition engine that decides where its numbers come from — AI only fills the very last gap, and always tells you when it did.

The nutrition engine: a tiered lookup, not a guess

Tier 1

IFCT 2017

528 verified ingredients (IFCT 2017) plus 44 curated composite dishes, matched with regional alias support.

Tier 2

USDA FoodData Central

The U.S. government's reference nutrition database, used when a food isn't in the local dataset.

Tier 3

Open Food Facts

An open, crowd-sourced database of packaged and branded products for items with a label.

Fallback only

AI estimate

Used only when nothing else matches — and the entry is always labeled as estimated, never hidden.

Every entry tells you where its numbers came from

Each logged food carries a visible data-source badge, so you always know whether a number came from a verified database or an AI guess.

  • No blind trust in AI-invented calories
  • Alternate food names resolve automatically — “cookie” and “biscuit” match the same entry
  • Count-based foods like “1 banana” convert to grams from real unit-weight data, not a guess

The resolve engine: figuring out which food you meant

This is the layer most food loggers skip entirely — and it's what makes the nutrition engine's answers trustworthy instead of a coin flip.

Typos & synonyms just work

Fuzzy trigram matching means "biryani" and "biriyani", "cookie" and "biscuit" all resolve to the same verified entry — no exact spelling required.

Smart enough to tell dishes apart

A word-by-word coverage check stops near-miss matches — "kanda bhaji" won't quietly get logged as "kanda poha" just because the two names look similar.

Your own recipes come first

Personal saved recipes are checked before the shared database, so your home-cooked version always wins over a generic match.

A database that grows itself

The first time anyone logs an unfamiliar dish, AI decomposes it once — the result is saved back into the shared database, so every match after that is instant and AI isn't needed again.

Everything else

A complete tracker, not just a food log

Nutrition is the headline, but Calzentra covers the rest of the picture too.

Workouts

Log walks with steps, runs, rides, swims and hikes with duration and distance, plus strength, HIIT, yoga and sports like football, cricket and badminton. Or just say it: “ran 5k in 28 minutes”.

Wellness

Track hydration with quick-add buttons and log sleep hours with a quality rating — the recovery metrics most trackers skip. Both can be logged by voice too.

Diet planner

Plan a full week of meals, copy a single day or the whole week forward, and log any planned meal in one click.

Recipes

Build recipes from ingredients — parsed by AI from text or voice — and get per-serving macros and micronutrients computed automatically.

Customizable dashboard

Build your own views from a library of widgets — quick-add weight, workout streak, charts, goal progress and more.

Goals

Set a weight goal, daily step target and calorie target, backed by a built-in BMI and calorie-goal calculator.

FAQ

Good to know

What's the difference between Free and Pro?

Every tracking feature — workouts, wellness, dashboard, recipes and goals — is free forever. Pro removes the monthly cap on AI-powered meal logging and adds priority processing and support.

Where does the nutrition data come from?

Every logged food is resolved through IFCT 2017, then USDA FoodData Central, then Open Food Facts, in that order — an AI estimate is only used as a last resort, and always labeled as such.

Do I have to use AI to log food?

No. Manual entry is unlimited on every plan — typing a sentence, snapping a photo or recording a voice note is just the fastest path.

Can I log workouts, water, sleep and weight by voice too?

Yes. Tap + and then Log by voice on any page and say something like “poha for breakfast, ran 5k in 28 minutes, drank 500 ml of water and slept 7 hours”. Calzentra sorts it into meals, a workout, water and sleep, puts each on the day and meal you mentioned, and lets you check and edit everything before one tap saves it all. If a day already has a sleep or weight entry, you'll see what it replaces before you save.

Which languages does voice logging understand?

Voice notes aren't limited to English — speak in Hindi, Marathi, Tamil, Spanish, French, Japanese or any of the many other languages our speech AI understands, and it transcribes exactly what you said. Accuracy is best for widely spoken languages, and you always review what was heard before saving.

Can I cancel Pro anytime?

Yes. Pro is billed monthly with no lock-in — cancel anytime and you'll keep full access to everything on the Free plan.
