Ordering coffee in Buenos Aires. Navigating a market in Rome. Checking into a hotel in Paris. Every scene has a goal — complete the checkpoints, get feedback on every response.

Ordering coffee in Buenos Aires

🇪🇸 720 A2
Carlos

¡Buenos días! ¿Qué desea ordenar?

Greet the barista and order a coffee

Hola, quiero un café con leche por favor.

Carlos

Perfecto, un café con leche. ¿Algo más?

Ask if they have any pastries

¿Puedo obtener unos pasteles?

Good Hide

“Obtener” is a direct translation of “to get.” It’s understandable, but a native speaker would not order food that way. In Spanish, you don’t need a verb like “obtener” to ask — just use “¿Tienes...?”

Better

¿Tienes pasteles también?

➤

Comprehensibility first.
The rest comes later.

At lower levels, we care most about whether you got your point across. As you improve, naturalness and form carry more weight.

Comprehensibility

Could a native speaker understand you? This is always the priority — if you can’t communicate, nothing else matters.

Naturalness

Does it sound like something a native would actually say? This is what separates textbook Spanish from real Spanish.

Form

Grammar, conjugation, spelling. Important, but weighted more heavily as your level increases.

Excellent 🇪🇸

Clear and natural. “Querría” is the right register for ordering — polite without being overly formal.

✓ Comprehensibility ✓ Naturalness ✓ Form
Good 🇫🇷

“Actuellement” means “currently,” not “actually.” Use “en fait” instead.

Better

En fait, je cherche la gare.

✓ Comprehensibility ✗ Naturalness ✓ Form
Needs Improvement 🇮🇹

“Vorrei il bagno” means “I’d like the bathroom.” To ask where it is, you need “dov’è.”

Better

Scusi, dov’è il bagno?

Track your fluency,
not your app usage.

Most apps give you points for showing up. Complete a lesson? +10 XP. Maintain your streak? +50 XP. But XP doesn't measure skill — it measures engagement.

We use an ELO rating system — the same mathematical model used to rank chess players worldwide. Your rating changes based on how you perform relative to the difficulty of what you're practicing.

↑ Perform well on a challenging scene → Rating goes up
↓ Struggle with an easy scene → Rating adjusts down
→ Over time, your rating converges on your true skill level
