fasting-tracker

What it does

Tracks intermittent and extended fasting windows with real-time elapsed time and countdown to metabolic milestones like ketosis, fat adaptation, and autophagy. Logs fast start and end times, calculates eating windows, and maintains history of past fasts. All data stays local on the user's machine.

Why it's useful

Combines real-time milestone tracking with historical stats in one place, so you don't need a separate app or manual spreadsheet.
