# 音壳 vs 开嗓练习

The clearest difference is update cadence: 音壳 at fortnightly against 开嗓练习's every 5 weeks. 音壳 also leads on ratings volume (19 vs 3). On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. 音壳 sells 11 one-off in-app purchases and 开嗓练习 sells 7 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
