The clearest difference is review sentiment: OVEY at 82% against 우체국's 19%. OVEY also leads on rating (4.6 vs 2.2) and update cadence (every 2 weeks vs every 2 months). On price, ads, 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.
