MacroFactor

MacroFactor is a nutrition-tracking and diet-coaching app built around a dynamic energy expenditure algorithm.

Rather than relying on a fixed calorie formula, it starts with a population-based estimate of your maintenance calories and then recalculates each week based on your logged intake and actual body-weight trend, automatically adjusting your calorie and macronutrient targets to keep you progressing toward a goal.

It supports several logging methods including database search, barcode scanning, a nutrition-label scanner, AI meal-photo logging, and voice entry, reducing the friction of tracking. A companion workouts feature provides resistance-training guidance such as warm-ups, rest times and rep-in-reserve programming.

It is aimed at fitness enthusiasts from beginners to experienced lifters who want transparent, science-based macro coaching without rigid meal plans, and it is supported by an active community.

Strengths include the adaptive algorithm, transparency about how targets are set, and flexible entry options; potential drawbacks are that it is a paid subscription with no permanently free tier and that, like any tracker, it depends on consistent and reasonably accurate logging.

It is a self-help nutrition tool, not personalized medical advice. Pricing changes often, so check the official site for current plans. MacroFactor is a real, live app available on iOS and Android.
