Macros that learn your metabolism.
Scan, log, weigh in — FITOS estimates your real daily expenditure from your own intake and weight trend, and recalculates your targets weekly.
Adaptive macros
No static formula. FITOS compares what you actually ate against how your smoothed weight trend moved, estimates your true maintenance calories, and resets your targets each week — showing the arithmetic behind every change. It needs regular food logs and weigh-ins to work, and says so when it can't.
