# iAnalyzer vs RTA Audio

The clearest difference is rating: iAnalyzer at 4.2 against RTA Audio's 3.5. iAnalyzer also leads on update cadence (every 5 months vs every 28 months) and iOS requirement (13.0 vs 15.6). RTA Audio's advantage is review sentiment (59% vs 41%). On price, ratings volume, ads and in-app purchases there is nothing between them.

Both are free to download. iAnalyzer sells 2 in-app purchases, starting at $4.99 per month and RTA Audio sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

iAnalyzer holds the better App Store score, 4.2 against 3.5. Both are backed by a comparable volume of ratings — 76 and 32 respectively. Written reviews complicate that: 41% of iAnalyzer's written reviews are positive against 59% of RTA Audio's, so the app with the better star average is not the one people write more warmly about.

iAnalyzer ships an update every 5 months, RTA Audio every 28 months. Both last shipped on October 23, 2026.
