# Conversion Calculator vs EchoRepeat

The clearest difference is ads: Conversion Calculator at none against EchoRepeat's shown. EchoRepeat's advantage is update cadence (every 2 weeks vs every 5 weeks) and iOS requirement (15.1 vs 17.0). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Conversion Calculator sells 1 one-off in-app purchase and EchoRepeat sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Conversion Calculator ships an update every 5 weeks, EchoRepeat every 2 weeks. The most recent releases landed on October 9, 2026 and October 1, 2026 respectively.
