CalZen Launches AI-Powered Calorie Tracking App That Logs Meals from a Photo

The new mobile app estimates calories and macros from a single photo—no typing, no barcode scans.

-- 42apps today announced CalZen, an AI calorie tracker that uses photo-based food logging to deliver automatic calorie counting and macro tracking from a single picture. Designed for people who find manual logging slow and inconsistent, CalZen applies AI food recognition to identify foods, estimate portions, and calculate calories, protein, carbs, and fat in seconds.

Unlike conventional apps that require typing, searching, or barcode scanning, CalZen uses the smartphone camera to analyze meals instantly. Users simply take a photo, and the app automatically detects foods, estimates portion sizes, and calculates calories, macros, and nutrition breakdowns within seconds.

Key Features

  • AI Meal Scanning (photo calorie counting): Take a photo; CalZen detects foods and estimates calories & macros automatically.
  • Auto-Save Food Log: Confirm and save in one tap; edit portions/items anytime.
  • Goal & Macro Targets: Set calorie or macro goals (cutting, maintenance, bulking) and adjust based on progress.
  • Clear, Minimal Interface: Built for speed and daily consistency.
  • Multilingual: English and Russian at launch; more languages coming.

“People want to eat better, but most apps turn tracking into a chore,” said Sergey Pakhandrin, CEO and Founder at 42apps. “CalZen reduces complexity — users only need to take a photo. Whether the goal is weight loss, muscle gain, or simply monitoring nutrition, the AI supports the process in the background.”

To mark the launch, premium features are available at an introductory reduced rate with promocode REDDIT70. Users can get started at no cost by downloading the app and scanning their first meals today.
