# apeMatrix vs RK

The clearest difference is price: RK at Free against apeMatrix's $14.99. RK also leads on rating (5.0 vs 4.7) and iOS requirement (13.0 vs 15.6). apeMatrix's advantage is update cadence (monthly vs every 5 months) and ratings volume (84 vs 9). On ads, in-app purchases and device support there is nothing between them.

RK is free to download; apeMatrix costs $14.99 up front. Neither carries in-app purchases, so what you see is what you pay.

RK holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: apeMatrix has 84 ratings behind it against 9, so its average is the more settled of the two. Written reviews complicate that: 75% of apeMatrix's written reviews are positive against 67% of RK's, so the app with the better star average is not the one people write more warmly about.

apeMatrix ships an update monthly, RK every 5 months. The most recent releases landed on September 21, 2026 and July 31, 2026 respectively.
