Twenty questions that climb from A1 to C1, scored so that the result reflects the level you can actually hold rather than an average. About four minutes, and nothing to sign up for.
More languages are coming. In the meantime, all 24 practice languages are already in the app.
You can handle the basics: greetings, introductions, numbers, and short set phrases. Conversation still runs on memorised chunks rather than sentences you build yourself.
You can get through predictable situations and talk about your own life in simple sentences. The past tense is arriving, but longer exchanges still fall apart.
You can hold a real conversation without much strain, and recover when you do not know a word. This is the level where most self-taught learners plateau, because reading and listening keep improving while speaking stops.
You can argue a point, follow fast speech, and use the language at work. What is left is precision: register, idiom, and the constructions that sound natural rather than merely correct.
You use the language flexibly and almost without hesitation, including in professional and academic settings. Remaining gaps tend to be idiom, cultural reference, and the rhythm of how things are actually said.
