# Zero vs Fasting Tracker

The clearest difference is review sentiment: Fasting Tracker at 94% against Zero's 33%. Fasting Tracker also leads on update cadence (every 3 days vs every 2 weeks) and rating (5.0 vs 4.8). Zero's advantage is ratings volume (445K vs 8.7K) and chart position (#115 vs unranked). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Zero sells 10 in-app purchases, starting at $9.99 per month and Fasting Tracker sells 17 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.

Fasting Tracker holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Zero has 445K ratings behind it against 8.7K, so its average is the more settled of the two. Written reviews point the same way: 33% of Zero's written reviews are positive against 94% of Fasting Tracker's.

Zero ships an update every 2 weeks, Fasting Tracker every 3 days. Both last shipped on September 24, 2026.
