Neat idea! Does it use spaced repetition, or some other way of deciding what words to show, when?

It's rather uses unix time instead of randomness. This manner you see the same words repeatedly when you have a intermediate timer (press button every 5 minutes), it's maths.

But look instead of using space repetiton, you can just remove words you've learnt from the words list.

Thanks
