Icon of the Krdz app Krdz 1.0

Krdz is an easy to use, non-distracting flash card app.

In Krdz, you create flash cards by simply writing them, like in a text editor or word processor.

Krdz uses spaced repition and knows when to show you a flash card for you to answer.

Krdz is available on the App Store.

What does "Krdz" mean?

"Krdz" is another way to write "cards". If you try to pronounce it then you would (most likely ^^) say "cards".
