# Launchmeter vs 测速仪

The clearest difference is in-app purchases: 测速仪 at none against Launchmeter's 1. 测速仪 also leads on iOS requirement (14.0 vs 17.0). On price, ads and device support there is nothing between them.

Both are free to download. Launchmeter sells 1 one-off in-app purchase. 测速仪 asks for nothing beyond the download.
