# LPG vs NoiseScope

The clearest difference is in-app purchases: LPG at none against NoiseScope's 1. LPG also leads on iOS requirement (13.0 vs 17.6). NoiseScope's advantage is device support. On price there is nothing between them.

Both are free to download. NoiseScope sells 1 one-off in-app purchase. LPG asks for nothing beyond the download.
