Best Thai English app

I’ve been using this app for 3+ years and have finally decided to write a review. I move back and forth between the US and TL and this app is 100% the best language app. It’s definitely slightly more useful if you speak a bit of both languages, since it gives all the different possible translations but IMHO this leads to better communication since other apps like google just directly translate in the most obvious way. It also provides audio for the words, and has a memory of your saved words (if you find yourself searching similar things frequently).

Great Thai-English Dictionary!

I used to use several Thai-Eng dictionary apps but I have finally stuck with only this one for several years. It is easy to search back and forth Thai to English and English to Thai. This app also aggregates data from several dictionary databases which is convenient to look up alternative meanings from other sources. However, I deduct 1 star from my rating for annoying ads that pop up so often when I am about to type the vocabulary down. Sometimes, I have to wait for 5 seconds in order to close the ads and continue typing. I know that is how you still manage to make this app free for us so I do not want to complain much. It just would be nice if it comes in a less annoying way.

A necessity!!!

By far the best dictionary app I have used, especially for Thai. It’s very difficult to find an app with an efficient interface and easy navigation. The highlighting function is absolutely essential in breaking down composite nouns and the like!!! I can trace nearly every word down by its syllable clusters, which is, again, absolutely amazing with a language like Thai. I am constantly opening the second pull-up/secondary search window and performing cross-searches to add more depth to my understanding of every word I learn.

Fantastic work! Thank you for this app.
