# RT vs ACR Product App

The clearest difference is rating: RT at 3.0 against ACR Product App's 1.7. RT also leads on chart position (#194 vs unranked). ACR Product App's advantage is in-app purchases (none vs 5) and review sentiment (22% vs 0%). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. RT sells 5 one-off in-app purchases. ACR Product App asks for nothing beyond the download.

RT holds the better App Store score, 3.0 against 1.7. Both are backed by a comparable volume of ratings — 8 and 36 respectively. Written reviews complicate that: 0% of RT's written reviews are positive against 22% of ACR Product App's, so the app with the better star average is not the one people write more warmly about.

RT ships an update monthly, ACR Product App every 2 months. The most recent releases landed on October 9, 2026 and October 24, 2026 respectively.
