# Wiki Search vs Deep Dictionary

Deep Dictionary's advantage is review sentiment (78% vs 50%) and update cadence (weekly vs every 2 weeks). On price, rating, 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.
