Cuaderno

español · a private notebook

Begin by writing what you want to say in English. Add your Spanish attempt if you have one — it's optional. Your tutor will mark it up like a letter.

Frases

Phrases you've saved from the tutor. Tap a row to reveal notes; the right column counts aciertos, parciales, fallos.

Examen

A small quiz drawn from your saved phrases — least-recently-tested first.
