# Ribn vs RK

The clearest difference is price: RK at Free against Ribn's $3.99. RK also leads on rating (5.0 vs 4.8). Ribn's advantage is update cadence (every 3 days vs every 5 months) and review sentiment (91% vs 67%). On ads, in-app purchases and device support there is nothing between them.

RK is free to download; Ribn costs $3.99 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 4.8. Both are backed by a comparable volume of ratings — 30 and 9 respectively. Written reviews complicate that: 91% of Ribn'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.
