# Echolism vs EF

The clearest difference is update cadence: EF at every 3 days against Echolism's monthly. EF also leads on device support (3 vs 1). On price, ads, in-app purchases and iOS requirement there is nothing between them.

Both are free to download. Echolism sells 12 in-app purchases, starting at $3.99 per month and EF sells 8 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

Echolism ships an update monthly, EF every 3 days. The most recent releases landed on September 24, 2026 and September 18, 2026 respectively.
