Verdict
The clearest difference is review sentiment: Thai Fast Dictionary at 60% against Dictionary.com's 26%. Thai Fast Dictionary also leads on rating (5.0 vs 4.8) and iOS requirement (14.0.0 vs 16.0). Dictionary.com's advantage is ratings volume (328K vs 1) and chart position (#128 vs unranked). On price, update cadence, 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. Dictionary.com sells 9 one-off in-app purchases and Thai Fast Dictionary sells 7 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.
Thai Fast Dictionary holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Dictionary.com has 328K ratings behind it against 1, so its average is the more settled of the two.
