# I vs Quiet Meter

The clearest difference is in-app purchases: I at none against Quiet Meter's 1. I also leads on ads (none vs shown) and device support (3 vs 1). On price there is nothing between them.

Both are free to download. Quiet Meter sells 1 one-off in-app purchase. I asks for nothing beyond the download.
