Overview
Zero is the most popular dedicated fasting app. It offers a clean fasting timer, multiple protocols, educational content about the science of fasting, and integration with Apple Health. If fasting is your primary focus, Zero does it well.
PT Tracker includes a full fasting tracker as one of many features — alongside workout logging, nutrition tracking, CrossFit timers, and AI coaching.

Where Zero Wins
- Dedicated fasting experience — the entire app is built around fasting, so the UX is very focused
- Extensive fasting education — articles and videos on autophagy, metabolic health, and fasting science
- Fasting-specific insights — detailed analytics about your fasting patterns over time
- Dr. Peter Attia involvement — credibility through association with respected health voices
Where PT Tracker Wins
- Fasting is just one feature — you also get workout tracking, nutrition, CrossFit, and AI coaching
- Nutrition tracking — see what you’re eating during your eating window with full macro breakdowns
- Workout logging — many people combine fasting with training; track both in one app
- CrossFit & functional fitness — timers for every workout format
- AI coaching — get advice on training, nutrition, and programming
- Social features — groups and challenges cover accountability for fasting and everything else
- Half the price — Zero Plus costs $9.99/mo; PT Tracker Pro is from £4.99/mo and includes everything
The Verdict
Zero is a well-made fasting app with genuinely useful educational content. But at $9.99/mo, you’re paying a premium for a single feature. PT Tracker includes fasting alongside workouts, nutrition, CrossFit timers, and AI coaching — all for roughly half the price. If fasting is part of your broader fitness journey (and it usually is), one app makes more sense than three.
