# Zettelheld vs Nox

The clearest difference is update cadence: Nox at weekly against Zettelheld's every 2 months. Nox also leads on ratings volume (6 vs 1). On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. Zettelheld sells 1 in-app purchase, starting at $1.99 per month and Nox sells 2 in-app purchases, starting at $11.99 per year. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 5.0 for Zettelheld against 5.0 for Nox. That said, the two scores are not equally well evidenced: Nox has 6 ratings behind it against 1, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.

Zettelheld ships an update every 2 months, Nox weekly. The most recent releases landed on September 21, 2026 and September 22, 2026 respectively.
