# Nerdish vs Kinnu

Nerdish and Kinnu both sit at 4.8 stars, but that hides the real split: 87% of Kinnu's written reviews are positive against 60% of Nerdish's. Nerdish's advantage is chart position (#89 vs unranked) and ratings volume (2.6K vs 494). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. Nerdish sells 5 in-app purchases, starting at $4.99 per month and Kinnu sells 4 in-app purchases, starting at $1.99 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 Nerdish against 4.8 for Kinnu. That said, the two scores are not equally well evidenced: Nerdish has 2.6K ratings behind it against 494, so its average is the more settled of the two. Written reviews are what separate them: 60% of Nerdish's written reviews are positive against 87% of Kinnu's.

Nerdish ships an update weekly, Kinnu every 6 days. The most recent releases landed on September 23, 2026 and September 22, 2026 respectively.
