What is 0xCal?

0xCal is an AI-powered calorie tracker that lets you log food by typing naturally or snapping a photo. Instead of searching databases or scanning barcodes, you describe your meal like texting a friend—and Gram, the built-in AI nutrition assistant, instantly calculates calories, protein, carbs, and fat. The app is designed with a dark-mode-first, minimal interface, weighs just 25MB, and integrates with Apple Health. It was featured as #1 Product of the Week in Health & Fitness on Product Hunt.

Who it's for

• Busy professionals tracking weight loss goals who want fast, frictionless logging without complex forms
• Fitness enthusiasts monitoring protein and macros who need instant, accurate nutrition data from natural language input
• Design-conscious users who value aesthetics and are tired of cluttered, bloated diet apps with outdated interfaces

Key features

Chat-based food logging

Type what you ate in plain English—like "scrambled eggs with toast and coffee"—and Gram instantly returns calories, protein, carbs, and fats. No database scrolling, no barcode scanning, no tedious forms. Logging a meal takes under 10 seconds.

Photo recognition

Snap a photo of any dish—home-cooked or restaurant food—and AI handles the rest. Perfect for busy mornings or quick logging on the go when typing feels like too much effort.

Macro tracking and weight logging

Beyond calories, 0xCal monitors protein, carbs, and fats with clean, visual charts. You can also log your weight and track progress over time with elegant graphs, all synced with Apple Health.

Beautiful dark mode design

The interface is optimized for OLED displays with clean typography and smooth animations. No ads, no bloat, no distractions—just a minimalist tool that looks and feels native to iOS.

What stands out

"Calorie counting doesn't have to feel like work."

0xCal reimagines food logging as a conversation rather than a chore. While most calorie apps are 200–600MB and packed with features you'll never use, 0xCal is just 25MB and focuses on one thing: making effortless tracking through natural language and photo recognition. The dark mode is genuinely beautiful, and the entire experience feels like it belongs on your home screen—not like a relic from 2015.

Worth checking out if…

You want a calorie tracker that feels like a native iOS app, not a database. If you're tired of scanning barcodes, searching endless meal libraries, or wrestling with cluttered dashboards, 0xCal offers a refreshingly simple alternative. It's especially suited for anyone who values clean design, fast logging, and AI that understands how you actually talk about food.
