# Sound vs NoiseLog

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

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