# ServerCat vs Zling

The clearest difference is update cadence: Zling at daily against ServerCat's every 6 days. Zling also leads on iOS requirement (15.1 vs 17.0). ServerCat's advantage is chart position (#28 vs unranked). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. ServerCat sells 3 in-app purchases, starting at $5.99 per year and Zling sells 2 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.

ServerCat ships an update every 6 days, Zling daily. The most recent releases landed on October 15, 2026 and October 8, 2026 respectively.
