A LingQ alternative built for Japanese and Chinese
Written by Darren Nah, who builds Toku Reader. Checked September 2026.
This is a narrow comparison on purpose. If you study several languages, the answer below is probably LingQ, and I will say so before I say anything else.
What LingQ is good at
LingQ reads in dozens of languages. Its App Store page calls it “A Better Path to Fluency”, and the thing it is really selling is scale: an enormous shared library of lessons with audio, the ability to import your own material, a running count of the words you know, a community that has been at it for years, and apps on the phone as well as a full site on a computer. It had over 10,000 ratings on the App Store and more than a million installs on Google Play when I checked in September 2026. That is not an accident.
If your list is Japanese, Spanish and Korean, one app that does all three is worth more than a better app that does one of them.
The trade-off, stated fairly
Anything that has to work in dozens of languages has to be general. That is not a criticism, it is arithmetic. But Japanese and Chinese are the two languages where general is expensive:
- Neither language puts spaces between words. Before a dictionary can be opened, something has to decide where each word ends — and in Japanese the same characters break differently depending on the sentence around them.
- Japanese kanji usually have more than one reading. 一日 is “ichinichi” in one sentence and “tsuitachi” in the next, and only the sentence tells you which.
- Chinese tones change depending on what follows. 不 and 一 shift, and two third tones in a row are not pronounced as written. Pinyin that ignores this is teaching the wrong sound.
What Toku Reader does about it
Two separate engines, one per language, neither pretending to be the other. The Japanese engine is held to 439 golden tests. The Chinese engine has roughly 800 tests written into the code, plus 1,178 saved sentences that are re-checked every time anything changes — so a fix for one word cannot quietly break a hundred others.
Both run on the phone, with their dictionaries inside the app. Traditional characters are treated as their own thing rather than converted to Simplified and back. There is no account, and nothing about the page you are reading is sent anywhere.
| LingQ | Toku Reader | |
|---|---|---|
| Languages | Dozens | Japanese and Chinese |
| Library | A very large shared one, plus your own imports | None of its own — you bring everything |
| Where the work happens | On its servers | On the phone |
| Offline | Lessons need to be fetched | Reading and lookups work with no signal |
| Account | Required | None |
The honest version
More languages, a bigger library, a longer track record: LingQ. Two languages that punish a general tool, handled by two engines built for them, on a phone, with nothing uploaded: this one. If you are learning Japanese in a Chinese-speaking country, or Chinese in Japan, it is also the only reader here that does not make you pick.
