The call

The clearest difference is rating: Deep Dictionary at 4.7 against Da Dictionary English's 4.2. Deep Dictionary also leads on in-app purchases (none vs 1) and update cadence (weekly vs every 10 months). Da Dictionary English's advantage is ads (none vs shown) and review sentiment (100% vs 78%).

ReceptionRating · Positive reviews · Number of ratings

Deep Dictionary holds the better App Store score, 4.7 against 4.2. That said, the two scores are not equally well evidenced: Deep Dictionary has 51 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 100% of Da Dictionary English's written reviews are positive against 78% of Deep Dictionary's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Da Dictionary English ships an update every 10 months, Deep Dictionary weekly. The most recent releases landed on September 30, 2026 and October 5, 2026 respectively.
