# Interval Jump vs Note Ninja

The clearest difference is rating: Interval Jump at 5.0 against Note Ninja's 4.5. Interval Jump also leads on ratings volume (22 vs 2) and chart position (#194 vs unranked). Note Ninja's advantage is in-app purchases (none vs 1) and review sentiment (100% vs 73%). On price, ads and device support there is nothing between them.

Both are free to download. Interval Jump sells 1 one-off in-app purchase. Note Ninja asks for nothing beyond the download.

Interval Jump holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Interval Jump has 22 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 73% of Interval Jump's written reviews are positive against 100% of Note Ninja's, so the app with the better star average is not the one people write more warmly about.

Interval Jump ships an update every 6 days, Note Ninja every 2 days. The most recent releases landed on October 25, 2026 and October 24, 2026 respectively.
