# Empty vs Ninja Intermittent Fasting

The clearest difference is rating: Empty at 4.5 against Ninja Intermittent Fasting's 4.0. Empty also leads on ratings volume (95 vs 4). Ninja Intermittent Fasting's advantage is review sentiment (100% vs 70%) and iOS requirement (12.0 vs 15.6). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Empty sells 1 one-off in-app purchase and Ninja Intermittent Fasting sells 1 in-app purchase, starting at $2.00 per month. Whichever you choose, the download price is not the number that matters.

Empty holds the better App Store score, 4.5 against 4.0. That said, the two scores are not equally well evidenced: Empty has 95 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 70% of Empty'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.

Empty ships an update every 6 months, Ninja Intermittent Fasting every 12 months. The most recent releases landed on September 8, 2026 and June 1, 2026 respectively.
