PT Tracker vs Life Fasting: Complete Comparison

All Comparisons

Overview

Life Fasting (now rebranded as Life Extend) pioneered the concept of fasting circles — small groups that fast together for accountability. It combines a fasting timer with social challenges and a community of fasters.

PT Tracker includes a fasting tracker alongside a full suite of fitness tools — workout logging, nutrition tracking, CrossFit timers, AI coaching, and its own social features.

Where Life Fasting Wins

• Fasting circles — the original group fasting concept with real-time participation tracking
• Dedicated fasting community — a user base specifically motivated by fasting goals
• Challenge system — structured fasting challenges that drive engagement and consistency
• Fasting-first design — every feature is oriented around the fasting experience

Where PT Tracker Wins

• Fasting plus everything else — workout tracking, nutrition, CrossFit, AI coaching, and gym finder
• Broader social features — groups and challenges aren’t limited to fasting; they cover all fitness goals
• Nutrition tracking — know exactly what you’re eating in your eating window
• Workout logging — most people who fast also train; track both without switching apps
• CrossFit & functional fitness — purpose-built timers for every format
• AI coaching — personalised advice on training, nutrition, and programming
• One app, not four — replace your fasting app, workout app, nutrition app, and community app

The Verdict

Life Fasting’s circles concept is clever, and if group fasting accountability is what keeps you consistent, it works. But fasting rarely exists in isolation — most people also train, track food, and want broader fitness community. PT Tracker’s social features cover group accountability for all goals, and its fasting tracker sits alongside everything else you need. One subscription, one app, everything covered.
