Why Quick Recall

The six things that matter

Most flashcard apps are just digital index cards. This one decides what to show you and when.

How it works

Here's the whole thing

1

Create or import

Build a deck from scratch or upload a CSV — every row becomes a flashcard instantly.

2

Study daily

Flip each card and rate it Hard, Good, or Easy. The algorithm decides when you'll see it next.

3

Track mastery

Watch mastery scores climb. Review weekly charts and see your study streak grow day by day.
