Fasting Tracker for long fast for iPhone

Begin extended fasts with clarity

Thinking about trying a multi-day fast but unsure how to start? The Fasting Tracker for long fast simplifies the process. Created by BerthX for iPhone, this free tool walks you through preparing for multi-day fasts (three days, four days, or longer) and supports a safe, structured refeeding period when you finish.

Key tools and insights

• Keep a history of past fasts with an easy-to-use logging section.
• View detailed progress metrics and various statistics to judge how well you’re doing.
• Track how long you’ve likely been in ketosis to better time your activities and refeed.
• Monitor each phase separately: preparation, fasting, and the refeeding window.

How it guides your fasting journey

The app separates the process into clear stages so you can plan and follow each phase deliberately. It helps you set and record preparation days, count fasting hours, and manage the gradual return to eating. That structure reduces guesswork and makes longer fasts more manageable.

Compatibility and safety notes

• Designed specifically for iPhone; the interface is not optimized for iPad screens.
• If you have existing medical issues or concerns, consult your primary care provider before beginning any extended fasting program.

Suggested companion app

If you want to keep better track of hydration during longer fasts, consider Hydro Coach — a free hydration app that pairs well with fasting routines.
