Verdict

The call

The clearest difference is price: Thai Fast Dictionary at Free against Advanced English Dictionary.'s $2.99. Thai Fast Dictionary also leads on rating (5.0 vs 4.7) and update cadence (every 6 weeks vs every 4 months). Advanced English Dictionary.'s advantage is in-app purchases (none vs 7) and ads (none vs shown). On device support and iOS requirement there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Thai Fast Dictionary holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Advanced English Dictionary. has 241 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 92% of Advanced English Dictionary.'s written reviews are positive against 60% of Thai Fast Dictionary's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Advanced English Dictionary. ships an update every 4 months, Thai Fast Dictionary every 6 weeks. Both last shipped on September 24, 2026.
