# VirtualKim vs RISC

The clearest difference is in-app purchases: RISC at none against VirtualKim's 1. RISC also leads on review sentiment (100% vs 85%). VirtualKim's advantage is ratings volume (31 vs 1) and iOS requirement (17.0 vs 26.0). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. VirtualKim sells 1 one-off in-app purchase. RISC asks for nothing beyond the download.

RISC holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: VirtualKim has 31 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 85% of VirtualKim's written reviews are positive against 100% of RISC's.

VirtualKim ships an update weekly, RISC every 2 weeks. The most recent releases landed on October 24, 2026 and October 30, 2026 respectively.
