Verdict

The call

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.

CostPrice · In-app purchases · Ads · Monetization

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.

ReceptionRating · Positive reviews · Number of ratings

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.

UpkeepUpdate frequency

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