Verdict

The call

The clearest difference is rating: Thai Fast Dictionary at 5.0 against Dictionary Offline's 4.6. Dictionary Offline's advantage is ratings volume (12K vs 1) and review sentiment (78% vs 60%). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Thai Fast Dictionary sells 7 in-app purchases, starting at $0.99 per month and Dictionary Offline sells 3 in-app purchases, starting at $5.99 per month. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Thai Fast Dictionary holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Dictionary Offline has 12K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 60% of Thai Fast Dictionary's written reviews are positive against 78% of Dictionary Offline's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Thai Fast Dictionary ships an update every 6 weeks, Dictionary Offline every 2 months. The most recent releases landed on September 24, 2026 and September 26, 2026 respectively.
