# 케이팝 RNX vs 시소

The clearest difference is update cadence: 시소 at every 2 weeks against 케이팝 RNX's every 6 weeks. 케이팝 RNX's advantage is device support (3 vs 1) and iOS requirement (13.0 vs 16.0). On price, ads and in-app purchases there is nothing between them.

Both are free to download. 케이팝 RNX sells 10 one-off in-app purchases and 시소 sells 5 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

케이팝 RNX ships an update every 6 weeks, 시소 every 2 weeks. The most recent releases landed on October 11, 2026 and September 23, 2026 respectively.
