## Overview

Fitscale is a small Streamlit health-calculator app. The user enters measurements or selects options in a tabbed interface; the app calculates BMI, BMR, target heart-rate ranges, TDEE, or goal-based macros and displays the result. All five workflows are implemented together in `Fitscale/healthcalc.py`, so the graph reflects functional stages, not separate runtime modules. The README documents these capabilities; the sampled source confirms their implementation. No separate storage or external service is shown.

Main entry points: [`Fitscale/healthcalc.py`](https://github.com/vx2-sagar-codes/fitscale-repo/blob/main/Fitscale/healthcalc.py) (Tabbed interface)
