Pure Macros is a calorie and macro tracker built around one idea: the basics shouldn't be paywalled. Point your camera at your food and AI estimates calories, protein, carbs, and fat. Barcode scanning, manual entry, exercise logging, and water tracking are free forever, no trial, no card required. The only paid feature is the AI photo scan, since it costs real money to run per scan. Built by one non-technical person in six weeks, working with Claude end to end.
