Verdict

The call

The clearest difference is rating: Thai English Dictionary + at 4.5 against Thai Fast Dictionary's 3.5. Thai English Dictionary + also leads on ratings volume (14 vs 2). Thai Fast Dictionary's advantage is review sentiment (60% vs 20%) and update cadence (every 6 weeks vs every 5 months). On price, ads, in-app purchases and monetization model 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 Thai English Dictionary + sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Thai English Dictionary + holds the better App Store score, 4.5 against 3.5. That said, the two scores are not equally well evidenced: Thai English Dictionary + has 14 ratings behind it against 2, 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 20% of Thai English Dictionary +'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, Thai English Dictionary + every 5 months. The most recent releases landed on October 23, 2026 and October 20, 2026 respectively.
