# OMR vs 채점비서

The clearest difference is update cadence: 채점비서 at every 2 days against OMR's every 5 weeks. 채점비서 also leads on iOS requirement (15.5 vs 17.6). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. OMR sells 1 one-off in-app purchase and 채점비서 sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

OMR ships an update every 5 weeks, 채점비서 every 2 days. The most recent releases landed on October 30, 2026 and October 31, 2026 respectively.
