Verdict

The call

The clearest difference is review sentiment: Kintore at 67% against AI Scale's 14%. Kintore also leads on update cadence (every 3 days vs every 3 months) and ratings volume (96 vs 1). AI Scale's advantage is in-app purchases (none vs 3) and rating (5.0 vs 4.8). On price, ads and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

AI Scale holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Kintore has 96 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 67% of Kintore's written reviews are positive against 14% of AI Scale's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Kintore ships an update every 3 days, AI Scale every 3 months. The most recent releases landed on September 23, 2026 and September 16, 2026 respectively.
