Verdict
The clearest difference is rating: CatNote at 5.0 against Kosaku's 4.6. Kosaku's advantage is ratings volume (18 vs 1) and iOS requirement (15.0 vs 18.2). On price, review sentiment, update cadence and ads there is nothing between them.

Both are free to download. Kosaku sells 3 in-app purchases, starting at $1.99 per month and CatNote sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
CatNote holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Kosaku has 18 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 93% of Kosaku's written reviews are positive against 100% of CatNote's.
Kosaku ships an update every 2 weeks, CatNote every 11 days. The most recent releases landed on November 8, 2026 and November 6, 2026 respectively.
