# InterFasting vs Intermittent Fasting Tracker

The clearest difference is ads: Intermittent Fasting Tracker at none against InterFasting's shown. Intermittent Fasting Tracker also leads on ratings volume (51K vs 267) and review sentiment (97% vs 88%). InterFasting's advantage is update cadence (every 2 days vs every 10 days) and iOS requirement (15.0 vs 17.0). On price, rating, in-app purchases and monetization model there is nothing between them.

Both are free to download. InterFasting sells 3 in-app purchases, starting at $3.99 per month and Intermittent Fasting Tracker sells 17 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.8 for InterFasting against 4.9 for Intermittent Fasting Tracker. That said, the two scores are not equally well evidenced: Intermittent Fasting Tracker has 51K ratings behind it against 267, so its average is the more settled of the two. Written reviews are what separate them: 88% of InterFasting's written reviews are positive against 97% of Intermittent Fasting Tracker's.
