Verdict

The call

The clearest difference is in-app purchases: YBM 올인올 영한 사전 at none against American Heritage® Dictionary's 1. YBM 올인올 영한 사전 also leads on price ($11.99 vs $12.99) and iOS requirement (9.0 vs 15.0). American Heritage® Dictionary's advantage is review sentiment (66% vs 33%) and update cadence (every 2 months vs every 8 months). On ads there is nothing between them.
