The Fasting Tracker App For Relentles Motivation and Expert Refeed Guidance

Stop guessing and start fasting with confidence.
SparkFast is the first app designed to solve the two biggest challenges fasters face.

A Fasting App That Solves the
Real Problems

Fasting is a powerful tool, but for both beginners and seasoned experts, two major hurdles can derail your progress: staying motivated and breaking the fast correctly. SparkFast was built from the ground up to solve these specific problems.

“I lose motivation and don’t know if it’s working.”
The fear of doing something wrong and a lack of motivation are the biggest pain points for fasters. It's hard to stay committed when you can't see the incredible benefits happening inside your body.
Relentless Motivation with the SPARK Chart
SparkFast provides a system of visual progress and science-backed insights to keep you engaged. Our unique SPARK chart shows you the estimated benefits in real-time, while automated messages keep you committed to your goals
"I'm afraid of breaking my fast the wrong way."
Most fasters lack knowledge on how to break a fast correctly to maximize benefits and avoid discomfort. Guessing what to eat can ruin your hard work.
Expert Refeed Guidance, Every Time
Our app removes the guesswork completely. SparkFast offers simple, preset protocols for breaking your fasts safely and effectively. This builds your confidence and ensures you get the most out of every fast.

A Scientific Approach to Fasting Motivation

Visualize Your Progress with the SPARK Chart

The SPARK Chart is a revolutionary feature that provides a visual representation of the estimated biological processes happening in your body as you fast. For the first time, you can watch your progress as the app tracks key benefit estimations over time, including:

Your Personal
Motivational Coach

The Motivational Engine is a background system that acts as your personal coach.

It is linked to your elapsed fasting time and sends timely, science-inspired push notifications that correspond to key milestones on the SPARK Chart , such as entering ketosis or reaching peak autophagy.

When you see a message that your body is beginning to reap a new benefit, you'll feel more committed than ever to completing your fast.
