About Fast Tracker

Fast Tracker is your trusted companion for navigating the journey of fasting with confidence, clarity, and insight.

Whether you're just beginning intermittent fasting or you're a seasoned multi-day faster, Fast Tracker helps you understand your body's rhythm—so you can fast smarter, not harder.

Why We Built Fast Tracker

Most fasting apps just count hours. We wanted something deeper.

  • • Predict how your body is likely to respond to fasting over time
  • • Track meaningful indicators like ketones, energy, and hunger
  • • Visualize the benefits of fasting and find your optimal routine
  • • Understand the science behind fasting, ketosis, and autophagy—without the fluff

We believe in empowering people to take charge of their health through data, education, and intuitive design.
