Learning even a little Thai changes a trip. A greeting, a thank-you and a few words for directions make taxi rides, market stalls and hotel check-ins easier, and most Thais appreciate any effort to speak their language. This guide covers the apps that have Thai courses, how Thai works, a simple plan for the weeks before you fly, and where to practise once you arrive.
App prices and plans change often, so this guide does not quote them. Check the current offer in your app store before you subscribe. The app details below were checked in September 2026.
Best Language Learning Apps for Thai
There is no single perfect app. Most learners do best with one course app for speaking, one tool for translation, and daily practice with real people. These are the tools with a confirmed Thai offer.
Pimsleur: Best for Speaking and Listening
Pimsleur has a course in Standard Thai, the Central Thai spoken in Bangkok and used across the country. The first lesson is free, so you can try the method before you pay.
It is an audio course: you listen, repeat and answer out loud, which trains your ear for the tones from the first day.
- Good for: speaking, pronunciation and listening
- Less good for: learners who want to start with reading and writing
- Best for: learners who like to study while walking, commuting or on a long flight

Ling: Short Lessons on Your Phone
Ling has a Thai course on iOS and Android, with a free trial. Its lessons are short and game-like, which makes it easy to fit a lesson into a coffee break.
- Good for: everyday vocabulary and phrases, and a first look at Thai script
- Less good for: long conversations
- Best for: beginners who want a daily habit on their phone

Google Translate: The Free Travel Tool
Google Translate is not a course, but it is the most useful free tool for a traveller in Thailand. You can type or speak a sentence and show the Thai translation to the person you are talking to.
It also works without mobile data, once you have downloaded Thai. In the app, tap the download icon next to the language, preferably on Wi-Fi. Do this at home before you fly, so the app works from the moment you land.

What Makes Thai Different
Five Tones
Central Thai has five tones: mid, low, falling, high and rising. The same syllable can mean different things depending on the tone. The standard example uses the syllable "kha":
| Tone | Thai | Meaning |
|---|---|---|
| Mid | คา | stick |
| Low | ข่า | galangal |
| Falling | ค่า | value |
| High | ค้า | to trade |
| Rising | ขา | leg |
Learn the idea of tones with this one set of words rather than long lists. You will make mistakes, and that is fine: Thais usually understand learners from the context.
The Thai Script
Thai has its own alphabet, which comes from the Old Khmer script. It has 44 consonant letters, two of which (ฃ and ฅ) are no longer used. It has 16 vowel symbols that combine into at least 32 vowel forms, plus 4 tone marks. Vowels can be written before, after, above or below a consonant, and words are written without spaces between them.
So the alphabet takes weeks, not days. On a short trip, focus on speaking. If you stay longer or return often, reading helps you understand street signs and menus.
One Official Language, Many Local Ones
Central Thai is the only official language, and it is what the apps teach. About 71 million people speak Thai as a first or second language (2024 estimate). More than 60 languages are spoken in Thailand, including Isan in the northeast (close to Lao), Northern Thai and Southern Thai. Most people in these regions also understand Central Thai, so the Thai you learn from an app is useful across the country.
Learning Strategy Tips
- Start with sounds and tones. Listen before you read.
- Learn polite phrases first. A few courteous words are more useful on a trip than a long word list.
- Add the script if you have time. Learn a few letters at a time.
- Practise a little every day. Short daily sessions work better than one long session a week.
A Simple Plan Before Your Trip
If you have a few weeks before you fly, this order works for most beginners:
| Stage | Focus | Tool |
|---|---|---|
| First weeks | Greetings, polite words, tones | Pimsleur, Ling |
| Middle weeks | Numbers, food, directions | Ling |
| Last week | Phrases for taxis, hotels and restaurants | Ling, Google Translate |
| Before you fly | Download Thai for offline use | Google Translate |
Phrases Worth Learning First
| English | Thai | Say it as |
|---|---|---|
| Hello | สวัสดี | sawatdee |
| Thank you | ขอบคุณ | khop khun |
| No problem | ไม่เป็นไร | mai pen rai |
| Go straight | ตรงไป | trong pai |
| Turn left | เลี้ยวซ้าย | liao sai |
| Turn right | เลี้ยวขวา | liao khwa |
| Stop here | จอดที่นี่ | jot thi ni |
End a sentence with khrap (ครับ) if you are a man or kha (ค่ะ) if you are a woman. These polite words make any phrase sound friendly and respectful: "sawatdee khrap", "khop khun kha".
Before You Fly: Downloads and Phone Setup
- Download Thai in Google Translate on Wi-Fi, so it works without data.
- Download your course lessons if your app allows offline use, so you can study on the plane.
- Plan your mobile data. Thailand has two main mobile network companies: AIS, and True Corporation, which runs both the TrueMove H and dtac brands. Tourist SIM cards and eSIMs are widely sold; compare the current offers before you buy.
- Save important numbers: 1155 for the Tourist Police, who have English-speaking staff, and 1669 for a medical emergency.
If you book an airport pickup with Smile Taxi Service, you get a free Thailand eSIM with 1 GB of data for 7 days (one per customer). We send you the link automatically after you book, in the Smile Taxi app, on WhatsApp or by email, and you can top up more data at smiletaxiservice.com/esim. It gets your phone online as soon as you land, so your translation app and messages work on the ride to your hotel.
Where to Practise Thai in Thailand
Practise in everyday situations, where people are used to short, simple exchanges:
- Street food stalls and markets. Ask for a dish, ask the price and say thank you. Numbers and food words come up again and again.
- Cafés and small shops. Greet the staff in Thai and order in Thai. Most people will help you with a word you do not know.
- Taxi rides. Directions are the most useful vocabulary for a traveller. Try "liao sai", "liao khwa" and "jot thi ni" with your driver.
In the northeast (Isan), people speak Isan at home but everyone understands Central Thai. Use your standard Thai phrases, and add "khop jai" (thank you in Isan) as a friendly extra.
Language-exchange events and apps are another option. Venues change often, so check current listings and meet in public places.
When Language Is a Problem
A few habits help when you do not know the words:
- Keep your address in Thai script. Save your hotel name and address in Thai on your phone, and show it to the driver. This avoids many misunderstandings.
- Call 1155 for help in English. The Tourist Police line has English-speaking staff. For police emergencies, call 191.
With Smile Taxi Service, you book and message the team in writing, in 10 languages, 24/7, on WhatsApp. Not every driver speaks English, but you can request an English-speaking driver when you book, subject to availability.
For example, a private transfer from Suvarnabhumi Airport to Bangkok costs a fixed 600 THB by sedan, 800 THB by SUV or 1,100 THB by van, per vehicle, one way, with expressway tolls included. The driver waits 60 minutes free, counted from the actual landing time, and you pay the driver in cash (THB) at the end of the trip. If you can only pay by card, message the team for a payment link (an extra fee for creating and handling the payment link may apply). Cancellation is free up to 24 hours before pickup. After that, a cancellation or change costs 25% (less than 24 h), 35% (less than 12 h) or 50% (less than 2 h) of the price, and a no-show 100%, also when you pay the driver in cash (details). Book a sedan from Suvarnabhumi Airport to Bangkok, or see all routes and prices.
