The Best Free App to Learn Thai in 2026 (Tried & Compared)

The best free app to learn Thai depends entirely on which kind of free you need: Anki is free forever and has real spaced repetition but no Thai content, Speekeo is free with no ads or paywall but teaches romanized speech only, and ThaiPod101's free lifetime account gives you 3–5 new lessons a week for as long as you want them. None of those three will ever ask you for money to keep going — which is more than can be said for most of the apps that advertise a "free" plan.

Full disclosure before you read another line: we make EffortlessThai, which appears near the bottom of this page with its own free tier. We've been specific about where that free tier stops, exactly as we've been specific about everyone else's.

"Free" means four different things

This is the whole reason the App Store is confusing. Sort the options by what "free" actually buys and the choice gets easy:

1. Free forever, no content. A tool, not a course. Anki is the archetype: brilliant engine, empty box.
2. Free forever, real content. Rare. Speekeo genuinely is this — no subscription, no ads, no paywalled lessons.
3. A free tier of a paid app. Real lessons, real ceiling. ThaiPod101, Ling, Drops, us.
4. A free trial. Not free at all, just deferred. Ling's is 7 days; ours is 14.

Almost every "best free Thai app" list you'll find quietly mixes category 4 in with category 1, which is how people end up surprised by a charge in week two.

The genuinely free options

Anki is the honest answer for anyone willing to do a little work. It's free on Windows, Mac, Linux, Android and through AnkiWeb in a browser; the only charge anywhere is a one-off $24.99 for AnkiMobile on iPhone and iPad, which funds the whole project. Its scheduling algorithm is the real thing — the same family of spaced repetition that makes vocabulary actually stick. The catch is that Anki ships with nothing in it. You either type your own Thai cards, which is slow and assumes you already know the tones, or you import a stranger's shared deck and inherit their mistakes. We've seen shared Thai decks with the tone marks simply missing from the romanization.

Speekeo is the surprise of this list: 100% free, no subscription, no ads, no paywalled content. It's built on the argument that learners spend months on the alphabet and never reach a conversation, so it teaches spoken Thai in the Latin alphabet first. If you already read Thai you can switch the script on, but it won't teach it to you. For a two-week holiday that trade is entirely reasonable. For a life in Thailand it eventually stops being.

thai-language.com isn't an app, but it's the free dictionary most long-term learners end up with open in a tab, and it costs nothing.

The free tiers of paid apps

App	What free gets you	Where free stops	Teaches Thai script?
ThaiPod101	Free lifetime account: 3–5 new lessons/week, first 3 lessons of every series (100+)	Full library needs Basic → Premium PLUS ($3.20–$12.58/mo on the current 24-month promo)	Partly
Ling	Limited lessons and dialogues, ad-supported	No flashcards, no exams, not all languages; Pro is $16.99/mo or $89.99/yr	Yes
Drops	Short daily sessions, ad-supported	Sessions are time-capped — "unlimited time" is literally a Premium feature ($11/mo, $69.99/yr, $150 lifetime)	Partly
EffortlessThai	3 curated starter decks + 1 custom deck of up to 10 cards, tone-coloured script and native audio, no time limit	8 more curated decks, unlimited cards and 14 days of full Pro on request; $20/mo or $120/yr after	Yes

A note on that table, because it's the sort of thing these comparisons get wrong: we re-checked every figure against the official pricing pages on 23 August 2026, and Drops had already moved from $13/mo to $11/mo since our July comparison of all seven Thai apps. Prices in this category drift constantly, and promotional rates are quoted as if permanent. If you're reading this months from now, click the source links.

If you arrived here from the most famous app of all: Duolingo has no Thai course for English speakers, free or paid, and hasn't for years.

The hidden cost of free romanization

Here's the part that decides whether a free app is a bargain or a detour. Thai is tonal, and most free tiers teach you romanized Thai without tone marks — which means six genuinely different words arrive in your head as three.

Learn "maa" from a romanization-only app and you have collapsed มา (maa, to come), ม้า (máa, horse) and หมา (mǎa, dog) into one sound. Learn "mai" and you've collapsed ไม่ (mâi, not), ใหม่ (mài, new) and ไหม (mǎi, the question particle) — three words you will use in your first real sentence. That's the deck on this page: the same six words, with the tone written into the colour of the script instead of left off it.

Untangling this later is genuinely harder than learning it right the first time, which is why we think the romanization system you pick matters less than whether it marks tone at all, and why learning the alphabet pays for itself faster than most beginners expect.

What we'd do with a budget of zero

Anki for retention, Speekeo for speaking, ThaiPod101's free account for listening, thai-language.com for lookups. That stack costs nothing, works forever, and asks perhaps an hour of setup — and it is a completely legitimate way to learn this language.

What it won't give you is native audio already attached to every card with the tone marked on the script, which is the specific gap we built our free tier to fill: three starter decks and ten cards of your own, no time limit, no card required. We capped that custom deck at ten cards deliberately rather than running a countdown — a free tier that expires isn't free, it's a trial wearing a costume.
