LingQ vs Readlang:
what’s worth paying for?

LingQ and Readlang, side by side

The web prices below were checked in USD. Annual plans require a larger upfront payment; the monthly equivalent is not a monthly billing option.

Published features and prices, checked September 21, 2026

What matters		Readlang
Core approach	Library and imports for reading with audio. [1]	Read texts, translate selections, review vocabulary. [2]
Premium, monthly	$14.99 [3]	$6 [4]
Premium, annual	$119.99 upfront About $10/month [3]	$48 upfront $4/month equivalent [4]
Free-plan limits to know	20 saved words/phrases; 5 imported lessons. [3]	Unlimited single-word translations; 10 phrase translations a day, up to 6 words each. [4]
Words it will teach you	No fixed course total established. Your selected material determines what you encounter.
Hours of learning content	Provider advertises thousands of audio hours; no audited per-language total established. [3]	No comparable catalogue total established. The 10-hour Premium allowance is audio storage. [4]
Proficiency outcome	We have not established a validated CEFR outcome for either product from the sources reviewed. See the evidence limits below.

“Unknown” means we lack a defensible number. It does not mean zero content or no learning value. Product claims and our interpretations are separated in our methodology.

The price difference is real. The value depends on your routine.

On the listed Premium plans, Readlang costs $8.99 less each month, or $71.99 less per year when comparing annual subscriptions. Those are calculations from the prices above, before any checkout-specific taxes, promotions or currency differences.

For someone who already has articles or books to read, a larger library may not justify the extra cost. For someone who loses study time searching for suitable material, it might. Make that decision around a week of actual use, not an imagined future habit.

Both providers also list higher tiers. LingQ Premium Plus adds AI-related features; Readlang Premium Plus is $15 monthly or $120 annually and includes 200 hours of audio storage. These are different packages, so matching the word “Plus” does not make them equivalent. [3] [4]

Check the live pricing pages before paying. A free account is useful for trying the workflow, but it cannot fully demonstrate a paid plan’s unlimited use.

How many words—and how fluent?

For these two tools, “how many words does it teach?” is the wrong kind of total. There is no single finite syllabus to count when learners bring in different texts. A meaningful comparison would need the same language, the same material and a clearly defined counting rule.

Consider English walk, walks and walked: three written forms can belong to one dictionary headword. A count of saved items also answers a different question from a count of words recalled later. Without the unit and test, a large vocabulary number tells us little.

LingQ’s support documentation describes a user-managed known-word system. That makes its counter useful for tracking activity, but it is not an independently administered vocabulary test. [5] We do not convert it into a CEFR level.

Likewise, hours available in a library are not hours you have studied. And reading a passage with translation help does not demonstrate that you can understand an unfamiliar conversation or speak spontaneously. Our verdict is about the study workflow; a stronger claim about proficiency would need separate evidence.

One learner’s useful distinction

The practical question is whether you need a reading tool for a particular device or a routine that moves between reading and listening. Two people studying the same language can reasonably choose differently.

A ten-minute comparison you can actually use

This is a suggested trial protocol, not a test we claim to have completed.

1. Choose a short text in your target language. Use something you have permission to import and would want to read even without an app.
2. Spend five minutes with each tool. Note how often you stop, whether the translation makes sense in context, and how easily you get back to the sentence.
3. Check the device you will really use. If listening matters, try the audio workflow separately. Confirm that the exact feature you need is available in your language and plan.
4. Come back tomorrow. Can you recall a few of yesterday’s words without hints? Which tool makes you want to finish the text?

Start monthly if you are still unsure. An annual discount saves money only if you keep using the product. If both workflows feel difficult, try an easier text before deciding that either app is the problem.
