Verdict
The clearest difference is review sentiment: RunKASI at 100% against FivePointFive's 59%. RunKASI also leads on rating (5.0 vs 4.8). FivePointFive's advantage is update cadence (every 5 days vs every 5 weeks) and ratings volume (4.9K vs 7). On price, ads, in-app purchases and monetization model 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. FivePointFive sells 5 in-app purchases, starting at $44.99 per 3 months and RunKASI sells 2 in-app purchases, starting at $59.99 per 6 months. Whichever you choose, the download price is not the number that matters.
RunKASI holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: FivePointFive has 4.9K ratings behind it against 7, so its average is the more settled of the two. Written reviews point the same way: 59% of FivePointFive's written reviews are positive against 100% of RunKASI's.
FivePointFive ships an update every 5 days, RunKASI every 5 weeks. The most recent releases landed on October 15, 2026 and October 4, 2026 respectively.
