# CalkCal vs Fasting + Intermittent Fasting

The clearest difference is in-app purchases: CalkCal at none against Fasting + Intermittent Fasting's 11. CalkCal also leads on rating (5.0 vs 4.8) and iOS requirement (8.0 vs 15.6). Fasting + Intermittent Fasting's advantage is ratings volume (6.8K vs 6) and review sentiment (74% vs 58%). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. Fasting + Intermittent Fasting sells 11 in-app purchases, starting at $1.99 per month. CalkCal asks for nothing beyond the download.

CalkCal holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Fasting + Intermittent Fasting has 6.8K ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 58% of CalkCal's written reviews are positive against 74% of Fasting + Intermittent Fasting's, so the app with the better star average is not the one people write more warmly about.

CalkCal ships an update every 9 days, Fasting + Intermittent Fasting every 2 weeks. The most recent releases landed on October 11, 2026 and October 16, 2026 respectively.
