# 그라운드 vs 시소

The clearest difference is in-app purchases: 그라운드 at none against 시소's 5. 그라운드 also leads on iOS requirement (13.0 vs 16.0). 시소's advantage is update cadence (every 2 weeks vs every 6 weeks). On price, ads and device support there is nothing between them.

Both are free to download. 시소 sells 5 one-off in-app purchases. 그라운드 asks for nothing beyond the download.

그라운드 ships an update every 6 weeks, 시소 every 2 weeks. The most recent releases landed on October 24, 2026 and September 23, 2026 respectively.
