Verdict
The clearest difference is review sentiment: Rock at 86% against Perspective AI's 32%. Rock also leads on monetization model (free with in-app purchases vs subscription) and ads (none vs shown). Perspective AI's advantage is update cadence (every 4 days vs every 3 weeks) and ratings volume (1.3K vs 65). On price and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Rock sells 3 in-app purchases, starting at $3.99 per 7 days and Perspective AI sells 6 in-app purchases, starting at $8.99 per 7 days. Whichever you choose, the download price is not the number that matters.
Rock holds the better App Store score, 4.4 against 3.9. That said, the two scores are not equally well evidenced: Perspective AI has 1.3K ratings behind it against 65, so its average is the more settled of the two. Written reviews point the same way: 86% of Rock's written reviews are positive against 32% of Perspective AI's.
Rock ships an update every 3 weeks, Perspective AI every 4 days. The most recent releases landed on November 4, 2026 and November 8, 2026 respectively.
