# Attenuator vs NetProbe

The clearest difference is update cadence: NetProbe at every 10 days against Attenuator's every 7 months. NetProbe also leads on device support (3 vs 1). Attenuator's advantage is ratings volume (8 vs 1) and iOS requirement (17.6 vs 26.2). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. Attenuator sells 1 one-off in-app purchase and NetProbe sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 5.0 for Attenuator against 5.0 for NetProbe. 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.

Attenuator ships an update every 7 months, NetProbe every 10 days. The most recent releases landed on October 1, 2026 and October 11, 2026 respectively.
