Verdict
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.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
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.
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.
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.
