Verdict

The call

The clearest difference is ads: 16 at none against Intermittent Fasting's shown. 16 also leads on rating (4.9 vs 4.5) and update cadence (every 5 days vs every 3 weeks). Intermittent Fasting's advantage is review sentiment (60% vs 50%) and iOS requirement (14.0 vs 16.2). On price, ratings volume, 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 8 in-app purchases, starting at $4.99 per 7 days and 16 sells 3 in-app purchases, starting at $6.99 per 7 days. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

16 holds the better App Store score, 4.9 against 4.5. Both are backed by a comparable volume of ratings — 102 and 64 respectively. Written reviews complicate that: 60% of Intermittent Fasting's written reviews are positive against 50% 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 every 3 weeks, 16 every 5 days. The most recent releases landed on October 21, 2026 and October 23, 2026 respectively.
