TruMac: Macro Calorie Tracker

TruMac is a nutrition tracking app that adjusts for real-world variation in food labels. By applying evidence-informed corrections to calories and macros, it helps you track what you’re likely eating — not just what the label claims — making it easier to reach fat loss, muscle gain, and performance goals. Nutrition labels are estimates. FDA nutrition labeling regulations allow for a degree of variance between labeled and actual nutritional values — commonly referenced as up to 20% under certain conditions. Nutritional values can also vary based on sourcing, processing, preparation, and manufacturing consistency. If you’ve ever felt like you’re tracking everything correctly, staying consistent, hitting your calorie target, and the scale still isn’t moving the way you expected, variability in nutritional data may be part of the reason. TruMac helps you account for that variability. Scan a barcode and TruMac applies an evidence-informed adjustment model based on food category, processing level, and available nutritional data. Instead of relying on a single rigid number, TruMac helps you track using realistic estimated macro ranges designed to keep you aligned with your nutrition goals. Whether your goal is fat loss, maintenance, or performance, TruMac is built to help you stay closer to your intended calorie and macro targets — including helping reduce the risk of drifting outside your intended calorie range. No black box. No guesswork.
