Whether you're on a short trip to Thailand, working with Thais, or studying the Thai language in-depth, this is the one dictionary you can really use. 195,000+ entries (250,000+ translations), plus a built-in phrasebook with 300+ categories and 12,000+ words and full-text searchable, ready-to-use customizable phrases. Clear native sound recordings for every Thai word—even offline. Favorites screen lets you organize words/phrases in multiple folders. Includes both pronunciation guides (12 different systems) and Thai Script with the Thai and English text as big as you want. Includes a guide to speaking and writing Thai and other mind-blowing features for exploring the Thai language—nothing else even comes close!

== Listen to Any Thai Word

Touch any Thai word/phrase in any of our 195,000+ entries to hear a high-quality sound recording of a native speaker, not a toneless gravelly robot as found in other software—more than 29 hours of studio-recorded sound included. Long-press to hear 2x/4x slow playback with no change in pitch.

== No Connection Required and No Data Charges

Works even when you're in a taxi or a countryside street market and not connected to the internet: all entries and sounds are stored right on your iPhone, iPad, or iPod Touch, and you will incur no data charges when you use the app.

== Big Text and Clear, Clean Layout

Make the Thai and English text as big as you want—no more reading glasses! Easily scroll through multiple, complete definitions on the screen at once. Customize layout.

== A Dictionary Crafted for Those Learning Thai

Unlike typical dictionaries based on low-quality, free internet data meant for Thai natives, our superb dictionary entries are hand-crafted by Paiboon Publishing with your needs in mind: if you're not familiar with the Thai alphabet, you can even look up Thai words by their sound using an easy-to-read pronunciation guide system (12 popular systems are supported). Hear somebody say "sa nuk?" Type "sa nuk" to find out what it means. All Thai words in every section are written using both Thai Script and your chosen pronunciation guide system(s).

Unlike dictionaries meant for Thais, we clarify critical shades of Thai word meaning and formality using English explanations, we list crucial Thai classifiers for more than 60,000 noun entries, and we even notate syllable stress.

== Built-In Phrasebook

Beginner or advanced, communicate in Thai easily! 12,000+ phrasebook entries in 300+ categories like “Language Difficulties,” “Hotel,” “Renting a Place,” “Food/Drink,” “Price Haggling,” “Transportation,” “Health,” “Shopping,” “Sightseeing,” “Love/Romance/Sex” and even “Swearing/Insults.” Two-way conversational format helps both of you communicate.

== Introduction to Thai Included

More than just a dictionary, our software includes a comprehensive, interactive introduction to the Thai language, including a "Speaking and Understanding" section with clickable sounds and detailed grammar coverage, and a "Reading and Writing" section with all the consonants and vowels in multiple, real-world fonts.

== Unique Thai Learning Tools

This app is loaded with amazing, industry-first Thai learning tools. You can touch any word to find out which component Thai words it's made from: a great way to learn new words quickly. You can see any Thai word written in multiple real-word fonts you are likely to see on signs and menus. You can touch any Thai word to see a detailed interactive breakdown of how to pronounce each syllable (with clickable sounds that let you compare nearby sounds) or see a detailed visual explanation of its Thai spelling—indispensable for learning how to read and write Thai.

Nothing like this has ever appeared in any dictionary software on any platform.

This App is an indispensable learning aid. While it contains some useful pointers, it is not a structured learning app with staged lessons. Its strength is as a constant companion to verify -and explain - spelling and sounds painlessly and efficiently, and help resolve anomalies and questions posed by material from other sources. It’s like having a native speaker permanently on hand to verify things with. This has been my second major attempt to lean Thai, the first attempt ended in frustration as every encountered question required research to resolve and ground overall progress to a halt. This app has been the difference this time around - rapid verification is essential to maintain momentum and help formulate understanding. It’s the most expensive app I’ve bought to date, but it’s absolutely been worth it and I wouldn’t hesitate to buy it again.

Best language learning app EVER

I've had an iphone for 8 years and downloaded oodles of apps, but this is the first review I've ever been moved to write, and for the priciest app I've ever bought. Worth every last penny. Simply excellent, and features such as Find Inside Words" really help you to have a better understanding of how the language is constructed, and therefore a closer feel for the culture. Brilliant, and can't fault it, and even at the price I think it is superb value!

Just amazing !!!!! 6 Stars!

I cannot speak too highly of this app. It's got everything and it works extremely well. I've been using this app for over 5 years now and it just keeps getting better!
