# Arzeko vs STIKO

The clearest difference is update cadence: Arzeko at every 5 weeks against STIKO's every 2 months. STIKO's advantage is iOS requirement (13.0 vs 15.5). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Arzeko ships an update every 5 weeks, STIKO every 2 months. The most recent releases landed on September 29, 2026 and October 16, 2026 respectively.
