# 回森 vs 开嗓练声

The clearest difference is update cadence: 回森 at every 6 days against 开嗓练声's every 4 weeks. 回森 also leads on ratings volume (1.2K vs 167). On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. 回森 sells 9 one-off in-app purchases and 开嗓练声 sells 6 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.7 for 回森 against 4.7 for 开嗓练声. That said, the two scores are not equally well evidenced: 回森 has 1.2K ratings behind it against 167, so its average is the more settled of the two. Written reviews are what separate them: 61% of 回森's written reviews are positive against 60% of 开嗓练声's.

回森 ships an update every 6 days, 开嗓练声 every 4 weeks. Both last shipped on November 7, 2026.
