Verdict

The call

The clearest difference is rating: LDict at 5.0 against Fastdic's 4.5. Fastdic's advantage is ratings volume (11K vs 2) and update cadence (every 5 weeks vs every 3 months). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. Fastdic sells 7 one-off in-app purchases and LDict sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

LDict holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Fastdic has 11K ratings behind it against 2, so its average is the more settled of the two. Written reviews split almost evenly too, at 76% and 77% positive.

UpkeepUpdate frequency

Fastdic ships an update every 5 weeks, LDict every 3 months. The most recent releases landed on October 29, 2026 and October 21, 2026 respectively.
