Get rewarded for teaching your language: how LangX scores a conversation
Most apps that reward you for learning a language reward you for doing it on your own: a lesson finished, a quiz passed, a streak kept. A language exchange works differently. What makes it useful is the other person — somebody who speaks the language you are learning, taking the time to help you with it, while you do the same for them.
So that is what LangX rewards. You earn LangX Tokens, an in-app point, for talking to people in the language you are learning and, above all, for helping them with yours.
A correction is worth ten messages
| What you do | Tokens |
|---|---|
| Send a message | 1 |
| Correct someone else’s sentence | 10 |
| Answer a pronunciation request with a recording | 10 |
| Start a conversation where both of you have spoken | 15 |
| Finish a review of ten Echo cards | 5 |
The gap between a message and a correction is deliberate. Sending a message is the easy part of an exchange. Stopping to fix a stranger’s sentence — and explaining why — is the part that actually teaches somebody something, and it is the harder thing to ask of anyone. A recording of how a word is said pays the same as a written correction, because it is the same act in a different medium.
Corrections have no daily cap. Teaching is the behaviour the app exists for, so there is no point at which doing more of it stops counting.
The caps are there so grinding does not win
Messages are a different story. Up to 200 messages a day pay, and at most 60 from any one person — so reaching the ceiling takes real conversations with at least four people. Two accounts typing at each other all day stop earning long before anyone who is actually practising would.
On top of that, a daily pool of 5,000 tokens is shared at the end of each day among everyone who was active, in proportion to how active they were. Nobody can take more than 5% of it. The score behind it counts new conversations, corrections and the number of different people you talked to more heavily than raw message volume: talking to four people beats sending four times as many messages to one.
Streaks pay too — a bonus at 7, 30, 100, 180, 365, 730 and 1,095 days, from 50 tokens at the first milestone to 25,000 at the last.
What you can spend them on
The list is short on purpose:
- A streak freeze (200), so one bad day does not undo months of practice.
- Filling in a missed day (600), within the last two weeks, twice a month.
- Frames and titles for your profile, from 1,000 to 100,000.
- Sticker packs to send in a chat, from 1,000.
Tokens cannot buy a paid feature. If they could, farming tokens would become a way around subscribing, and the subscription is what pays for the app. Keeping them to cosmetics and the streak is what lets the app be generous with them.
What they are not
LangX Token is not a cryptocurrency. It is not on a blockchain, it cannot be bought, sold, traded, sent to someone else or withdrawn, and it has no cash value. An earlier version of LangX described something tradable; that was never built and is not planned. If you had tokens in the old app, your balance carried over, divided by 100 — the reasoning is here.
Every number, in one place
These are the current values, and they are public: they live in the app’s open-source code, and they will be tuned as we learn how the economy behaves with real activity. The full set — the pool formula, the hourly gift, invites — is on token.langx.io, in the app’s eight languages, and in every rule on this site.
The quickest way to see it work is to write to somebody and fix one of their sentences. That is ten tokens, and somebody’s language got a little better.
