# Echo vs Logic Arcade

The clearest difference is ads: Logic Arcade at none against Echo's shown. Logic Arcade also leads on iOS requirement (15.1 vs 17.0). Echo's advantage is update cadence (every 4 days vs monthly). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Echo sells 1 one-off in-app purchase and Logic Arcade sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Echo ships an update every 4 days, Logic Arcade monthly. The most recent releases landed on October 25, 2026 and October 24, 2026 respectively.
