Key Takeaway: Zero Fasting has locked essential features behind a steep $69.99/year paywall. Simple Fasting Tracker (FastingTracker.net) provides complete biological autophagy stage tracking, all standard protocols (16:8, OMAD), and a clean interface without predatory upsells.
The 2026 Fasting App Problem
Fasting apps originally became popular because intermittent fasting is simple and free. Unfortunately, legacy apps like Zero have added intrusive quizzes, locked basic statistics behind expensive subscriptions, and made logging unnecessarily complicated.
