# 精准分贝仪 vs 分贝仪

The clearest difference is in-app purchases: 精准分贝仪 at none against 分贝仪's 1. 精准分贝仪 also leads on iOS requirement (13.0 vs 15.6). 分贝仪's advantage is device support. On price there is nothing between them.

Both are free to download. 分贝仪 sells 1 in-app purchase, starting at $2.99 per month. 精准分贝仪 asks for nothing beyond the download.
