Vocabulary that grows while you rest.

A few new words a day in the language you're learning, brought back just before you'd have lost them.

Resting is part of the work

Words come back just before they slip away, and new ones arrive only when the old ones sit well. A few a day, for as long as you like.

Range before polish

Following a conversation takes many words, not a few perfect ones. Spross spends your minutes on breadth — numbers, times, years, sentences — all generated, so practice never runs out.

Your own box, on your device

Words you pick up in the wild go in the same box as the catalog, and the catalog never touches what's yours. No account, no ads; the box lives on your device and nowhere else.

A companion, not a replacement

It sits beside your course or tandem partner and keeps vocabulary growing between them. No grammar lessons, no curriculum to fall behind on.

It's still growing. Want a note when it's out?

One short message when Spross reaches the stores, and the odd one after that when something worth telling you about has grown in.
