# 回音 vs Simple

The clearest difference is ads: Simple at none against 回音's shown. Simple also leads on update cadence (every 3 days vs every 3 weeks). 回音's advantage is review sentiment (88% vs 56%) and ratings volume (93 vs 10). On price, rating, in-app purchases and monetization model there is nothing between them.

Both are free to download. 回音 sells 13 in-app purchases, starting at $3.99 per month and Simple sells 24 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.5 for 回音 against 4.6 for Simple. That said, the two scores are not equally well evidenced: 回音 has 93 ratings behind it against 10, so its average is the more settled of the two. Written reviews are what separate them: 88% of 回音's written reviews are positive against 56% of Simple's.

回音 ships an update every 3 weeks, Simple every 3 days. Both last shipped on September 25, 2026.
