## What is Calvin?

Photograph a meal. Calvin reads the nutrition and shows you how it got there.

Most calorie apps give you one number and no way to tell whether it's any good. Calvin breaks every meal down food by food, so you can see the estimate for the rice, the chicken and the dressing separately, adjust a portion, or correct an item it misread. The total updates as you go.

START WITH A PHOTO
Take a photo and Calvin identifies the foods on the plate, estimates portions, and works out calories, protein, carbs, fat and fiber. There is no scale to fetch and no database to scroll through first.

Not in the mood for a photo? Type "coffee with oat milk" or "chicken stir fry" in plain English, scan a barcode, or search for a food directly.

CHECK THE MATH
Every entry opens into the individual foods behind it, each with its own calorie count. Change the portion size and everything recalculates. Fix a misidentified item and the day updates to match.

Calvin also shows you how confident it is in a reading, so you know when a number is worth a second look.

SEE YOUR WHOLE DAY
Calories, macros, water and weight in one view, with a ring that tells you where you stand against your goal at a glance.

WEIGHT WITHOUT THE PANIC
Log your weight and Calvin plots the trend rather than the daily jitter, so one heavy morning doesn't read as a setback.

INSIGHTS THAT SAY SOMETHING
Weekly summaries in plain language: what your protein averaged, whether calories moved, how long your logging streak is, and where the week actually differed from the last one.

A RECORD YOU CAN GO BACK TO
Browse any past day, add a meal you forgot, or correct an old entry. Your history stays editable.

ALSO INCLUDED
- Water tracking with one-tap logging
- Barcode scanning for packaged food
- Apple Health integration
- Daily streaks and progress
- Light and dark themes

FREE AND PRO
Calvin is free to use: photo logging, plain-text entry, barcode scanning, food search, water and weight tracking, basic insights, and your last 7 days of history. The free tier includes 20 photo analyses a day.

Calvin Pro raises that to 100 photo analyses a day and adds your full history, advanced insights and weight predictions, priority processing, and data export. Pro is $9.99 per month or $79.99 per year (about 33% less), and starts with a 7-day free trial. Cancel any time during the trial and you won't be billed.

A note on accuracy: Calvin's readings are estimates, not lab measurements. They are good enough to steer by and they are always yours to correct. Calvin is a food logging tool, not medical advice. Talk to a doctor or a registered dietitian about your own nutrition needs.
