# VKos vs Echo

The clearest difference is review sentiment: VKos at 68% against Echo's 3%. VKos also leads on iOS requirement (14.0 vs 16.0). Echo's advantage is update cadence (every 8 days vs every 6 weeks). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. VKos sells 7 one-off in-app purchases and Echo sells 5 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

VKos ships an update every 6 weeks, Echo every 8 days. The most recent releases landed on October 15, 2026 and October 14, 2026 respectively.
