# Z vs 스르륵

The clearest difference is in-app purchases: Z at none against 스르륵's 1. Z also leads on device support (3 vs 1) and iOS requirement (13.3 vs 16.0). 스르륵's advantage is update cadence (every 3 days vs every 6 weeks). On price and ads there is nothing between them.

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

Z ships an update every 6 weeks, 스르륵 every 3 days. The most recent releases landed on October 25, 2026 and November 1, 2026 respectively.
