# 짐드림 vs HD

The clearest difference is update cadence: HD at every 2 weeks against 짐드림's every 15 months. HD also leads on device support and iOS requirement (12.0 vs 14.0). On price 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.

짐드림 ships an update every 15 months, HD every 2 weeks. The most recent releases landed on September 27, 2026 and September 29, 2026 respectively.
