# RF Tools vs RF Signal Detector

The clearest difference is review sentiment: RF Tools at 60% against RF Signal Detector's 11%. RF Tools also leads on in-app purchases (none vs 4) and ads (none vs shown). RF Signal Detector's advantage is rating (4.2 vs 3.0) and update cadence (monthly vs every 14 months). On price, device support and iOS requirement there is nothing between them.

Both are free to download. RF Signal Detector sells 4 in-app purchases, starting at $8.99 per 7 days. RF Tools asks for nothing beyond the download.

RF Signal Detector holds the better App Store score, 4.2 against 3.0. That said, the two scores are not equally well evidenced: RF Signal Detector has 99 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 60% of RF Tools's written reviews are positive against 11% of RF Signal Detector's, so the app with the better star average is not the one people write more warmly about.

RF Tools ships an update every 14 months, RF Signal Detector monthly. The most recent releases landed on October 5, 2026 and October 14, 2026 respectively.
