THE ALGORITHM

Truth is in the Trend.

Static formulas belong in textbooks. MacroJimmy adapts to your bio-data in real-time. We don't care what a calculator says you *should* burn. We track what you *actually* burn.

Σ

EWMA Engine

Exponentially Weighted Moving Averages eliminate the noise of daily water weight swings. We isolate the real metabolic signal through the chaos.

👁️

Gemini Vision

Powered by Google's latest multimodal models. Snap a photo, get an instant estimate, move on. Speed is the only metric that matters.

⚖️

Adaptive Feedback

Every gram of food and every milligram of mass is a data point. The engine recalibrates your targets every 24 hours based on real performance.
