# Koham vs OnePage

The clearest difference is monetization model: Koham at free with in-app purchases against OnePage's paid. OnePage's advantage is update cadence (every 3 days vs weekly) and ratings volume (6 vs 1). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. Koham sells 1 one-off in-app purchase and OnePage sells 3 one-off in-app purchases. 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 Koham against 5.0 for OnePage. That said, the two scores are not equally well evidenced: OnePage has 6 ratings behind it against 1, so its average is the more settled of the two.

Koham ships an update weekly, OnePage every 3 days. The most recent releases landed on October 31, 2026 and November 6, 2026 respectively.
