Verdict

The call

The clearest difference is review sentiment: 16 at 100% against Intermittent Fasting's 50%. 16 also leads on iOS requirement (13.0 vs 16.0). Intermittent Fasting's advantage is rating (4.8 vs 4.0) and ads (none vs shown). On price, in-app purchases, monetization model and device support there is nothing between them.

CostPrice · In-app purchases · Ads · Monetization

Both are free to download. Intermittent Fasting sells 11 in-app purchases, starting at $3.99 per 7 days 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, 4.8 against 4.0. That said, the two scores are not equally well evidenced: Intermittent Fasting has 1K ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 50% 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 every 2 weeks, 16 every 6 weeks. The most recent releases landed on September 22, 2026 and September 17, 2026 respectively.
