# XKey vs KYDZ

The clearest difference is rating: XKey at 5.0 against KYDZ's 4.1. XKey also leads on review sentiment (100% vs 75%) and iOS requirement (9.0 vs 15.0). KYDZ's advantage is update cadence (every 9 days vs every 10 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. Neither carries in-app purchases, so what you see is what you pay.
