0xCal

0xCal is an AI-powered calorie tracking app for iPhone that makes meal logging effortless through photo recognition and natural language chat. Instead of tediously searching databases or scanning barcodes, you simply snap a photo of your meal or describe what you ate to "gram," your AI nutrition assistant, which instantly calculates calories, carbs, protein, and fats. The app features a beautiful dark-mode-first interface designed for people who care about aesthetics as much as functionality, and integrates seamlessly with Apple Health for accurate calorie targets based on your activity level.

Getting started with 0xCal is simple and takes just a few minutes to set up your personalized calorie tracking experience.

2. Connect Apple Health - Link the app to Apple Health to sync your weight, steps, and workouts. This integration ensures your calorie targets automatically adjust based on your activity level.

3. Log Meals with Photo or Chat - Take a photo of your meal for instant AI recognition, or simply describe what you ate in natural language (e.g., "scrambled eggs with toast and coffee"). The AI assistant gram handles all the calculations instantly.

4. Review and Refine - Check the nutritional breakdown and chat with gram to adjust portions or add details if needed. The more context you provide, the more accurate your tracking becomes.
