# Intermittent Fasting vs 16

The clearest difference is rating: Intermittent Fasting at 4.7 against 16's 4.0. Intermittent Fasting also leads on ratings volume (551 vs 4) and update cadence (fortnightly vs every 6 weeks). 16's advantage is review sentiment (100% vs 65%) and iOS requirement (13.0 vs 16.0). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Intermittent Fasting sells 14 in-app purchases, starting at $4.99 per month and 16 sells 5 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Intermittent Fasting holds the better App Store score, 4.7 against 4.0. That said, the two scores are not equally well evidenced: Intermittent Fasting has 551 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 65% of Intermittent Fasting's written reviews are positive against 100% of 16's, so the app with the better star average is not the one people write more warmly about.

Intermittent Fasting ships an update fortnightly, 16 every 6 weeks. The most recent releases landed on October 23, 2026 and October 21, 2026 respectively.
