Verdict
Fastdic and LDOCE (InApp) both sit at 4.5 stars, but that hides the real split: 71% of Fastdic's written reviews are positive against 40% of LDOCE (InApp)'s. Fastdic also leads on ratings volume (11K vs 1.2K). On price, rating, update cadence and ads 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 LDOCE (InApp) sells 5 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.
On the App Store both sit at effectively the same score — 4.5 for Fastdic against 4.4 for LDOCE (InApp). That said, the two scores are not equally well evidenced: Fastdic has 11K ratings behind it against 1.2K, so its average is the more settled of the two. Written reviews are what separate them: 71% of Fastdic's written reviews are positive against 40% of LDOCE (InApp)'s.
Both ship on a similar rhythm, roughly every 5 weeks. The most recent releases landed on September 29, 2026 and September 28, 2026 respectively.
