# RTA vs iAnalyzer

The clearest difference is price: iAnalyzer at Free against RTA's $4.99. iAnalyzer also leads on rating (4.2 vs 3.9) and iOS requirement (13.0 vs 15.0). RTA's advantage is review sentiment (61% vs 41%). On ratings volume, update cadence, ads and in-app purchases there is nothing between them.

iAnalyzer is free to download; RTA costs $4.99 up front. RTA sells 2 one-off in-app purchases and iAnalyzer sells 2 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

iAnalyzer holds the better App Store score, 4.2 against 3.9. Both are backed by a comparable volume of ratings — 26 and 75 respectively. Written reviews complicate that: 61% of RTA's written reviews are positive against 41% of iAnalyzer's, so the app with the better star average is not the one people write more warmly about.

RTA ships an update every 3 months, iAnalyzer every 5 months. The most recent releases landed on October 13, 2026 and October 11, 2026 respectively.
