# Rhythm vs Ninja Intermittent Fasting

The clearest difference is rating: Rhythm at 4.7 against Ninja Intermittent Fasting's 4.0. Rhythm also leads on in-app purchases (none vs 1) and ads (none vs shown). Ninja Intermittent Fasting's advantage is review sentiment (100% vs 89%) and iOS requirement (12.0 vs 17.6). On price, update cadence and device support there is nothing between them.

Both are free to download. Ninja Intermittent Fasting sells 1 in-app purchase, starting at $2.00 per month. Rhythm asks for nothing beyond the download.

Rhythm holds the better App Store score, 4.7 against 4.0. That said, the two scores are not equally well evidenced: Rhythm has 458 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 89% of Rhythm's written reviews are positive against 100% of Ninja Intermittent Fasting's, so the app with the better star average is not the one people write more warmly about.

Rhythm ships an update every 13 months, Ninja Intermittent Fasting every 12 months. The most recent releases landed on October 23, 2026 and October 2, 2026 respectively.
