Verdict

The call

The clearest difference is review sentiment: iFast at 86% against Intermittent Fasting's 50%. iFast also leads on in-app purchases (none vs 11) and update cadence (every 3 days vs every 2 weeks). Intermittent Fasting's advantage is ads (none vs shown) and ratings volume (1K vs 22). On price and iOS requirement there is nothing between them.

Both are free to download. Intermittent Fasting sells 11 in-app purchases, starting at $3.99 per 7 days. iFast asks for nothing beyond the download.

ReceptionRating · Positive reviews · Number of ratings

Intermittent Fasting holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: Intermittent Fasting has 1K ratings behind it against 22, so its average is the more settled of the two. Written reviews complicate that: 50% of Intermittent Fasting's written reviews are positive against 86% of iFast'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, iFast every 3 days. The most recent releases landed on October 16, 2026 and October 9, 2026 respectively.
