# 水平仪 vs 水平尺

The clearest difference is in-app purchases: 水平仪 at none against 水平尺's 1. 水平尺's advantage is ads (none vs shown) and iOS requirement (13.0 vs 15.6). On price and device support there is nothing between them.

Both are free to download. 水平尺 sells 1 in-app purchase, starting at $1.99 per 7 days. 水平仪 asks for nothing beyond the download.
