# Attenuator vs RF Power Calculator

The clearest difference is in-app purchases: RF Power Calculator at none against Attenuator's 1. RF Power Calculator also leads on device support (3 vs 1) and iOS requirement (9.0 vs 17.6). Attenuator's advantage is ratings volume (8 vs 1). On price, rating and ads there is nothing between them.

Both are free to download. Attenuator sells 1 one-off in-app purchase. RF Power Calculator asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 5.0 for Attenuator against 5.0 for RF Power Calculator. That said, the two scores are not equally well evidenced: Attenuator has 8 ratings behind it against 1, so its average is the more settled of the two.
