Intermittent Fasting Tracker Х also leads on iOS requirement (15.6 vs 17.0). Zero's advantage is ratings volume (445K vs 2) and chart position (#112 vs unranked).

Both are free to download. Zero sells 10 in-app purchases, starting at $9.99 per month and Intermittent Fasting Tracker Х sells 11 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.
