# Arkio vs Zettelheld

The clearest difference is rating: Zettelheld at 5.0 against Arkio's 3.1. Zettelheld also leads on review sentiment (100% vs 80%). Arkio's advantage is update cadence (every 3 weeks vs every 2 months) and ratings volume (7 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Arkio sells 5 in-app purchases, starting at $19.99 per month and Zettelheld sells 1 in-app purchase, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

Zettelheld holds the better App Store score, 5.0 against 3.1. That said, the two scores are not equally well evidenced: Arkio has 7 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 80% of Arkio's written reviews are positive against 100% of Zettelheld's.

Arkio ships an update every 3 weeks, Zettelheld every 2 months. The most recent releases landed on October 7, 2026 and October 8, 2026 respectively.
