# R2G vs 洛克兄弟

The clearest difference is rating: R2G at 5.0 against 洛克兄弟's 3.9. 洛克兄弟's advantage is review sentiment (50% vs 20%) and ratings volume (14 vs 1). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

R2G holds the better App Store score, 5.0 against 3.9. That said, the two scores are not equally well evidenced: 洛克兄弟 has 14 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 20% of R2G's written reviews are positive against 50% of 洛克兄弟's, so the app with the better star average is not the one people write more warmly about.

R2G ships an update every 5 weeks, 洛克兄弟 every 2 months. The most recent releases landed on November 8, 2026 and October 30, 2026 respectively.
