# ZEdit vs OS One

The clearest difference is update cadence: OS One at every 4 days against ZEdit's every 2 weeks. ZEdit's advantage is iOS requirement (17.0 vs 26.0). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. ZEdit sells 1 one-off in-app purchase and OS One sells 3 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

ZEdit ships an update every 2 weeks, OS One every 4 days. The most recent releases landed on October 6, 2026 and September 30, 2026 respectively.
