# RF Tools vs Electronic Circuit Calculator

The clearest difference is review sentiment: RF Tools at 60% against Electronic Circuit Calculator's 14%. RF Tools also leads on in-app purchases (none vs 1) and ads (none vs shown). Electronic Circuit Calculator's advantage is rating (4.0 vs 3.0) and update cadence (every 2 months vs every 14 months). On price, ratings volume, monetization model and device support there is nothing between them.

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

Electronic Circuit Calculator holds the better App Store score, 4.0 against 3.0. Both are backed by a comparable volume of ratings — 3 and 5 respectively. Written reviews complicate that: 60% of RF Tools's written reviews are positive against 14% of Electronic Circuit Calculator'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, Electronic Circuit Calculator every 2 months. The most recent releases landed on October 5, 2026 and October 13, 2026 respectively.
