Verdict

The call

The clearest difference is monetization model: Fastdic at free with in-app purchases against English Dictionary's subscription. Fastdic also leads on ratings volume (11K vs 1.2K) and device support (3 vs 1). English Dictionary's advantage is ads (none vs shown) and update cadence (every 9 days vs every 5 weeks). On price, rating, review sentiment and in-app purchases there is nothing between them.

CostPrice · In-app purchases · Ads · Monetization

Both are free to download. Fastdic sells 7 one-off in-app purchases and English Dictionary sells 9 in-app purchases, starting at $2.99 per 7 days. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

On the App Store both sit at effectively the same score — 4.5 for Fastdic against 4.6 for English Dictionary.
