# Zero vs Intermittent Fasting Timer 168

The clearest difference is review sentiment: Intermittent Fasting Timer 168 at 79% against Zero's 32%. Intermittent Fasting Timer 168 also leads on iOS requirement (15.6 vs 17.0). Zero's advantage is rating (4.8 vs 4.3) and ratings volume (445K vs 21). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Zero sells 10 in-app purchases, starting at $9.99 per month and Intermittent Fasting Timer 168 sells 6 in-app purchases, starting at $7.99 per month. Whichever you choose, the download price is not the number that matters.

Zero holds the better App Store score, 4.8 against 4.3. That said, the two scores are not equally well evidenced: Zero has 445K ratings behind it against 21, so its average is the more settled of the two. Written reviews complicate that: 32% of Zero's written reviews are positive against 79% of Intermittent Fasting Timer 168's, so the app with the better star average is not the one people write more warmly about.

Zero ships an update every 2 weeks, Intermittent Fasting Timer 168 every 3 weeks. The most recent releases landed on November 2, 2026 and October 24, 2026 respectively.
