# Q vs 자등명

The clearest difference is ads: 자등명 at none against Q's shown. Q's advantage is iOS requirement (15.0 vs 17.0). On price, update cadence, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Q ships an update every 6 days, 자등명 every 11 days. The most recent releases landed on October 19, 2026 and October 4, 2026 respectively.
