The most I like is the rating sistem and the algorythm that is use, in order to repeat the questions just before your short term memory is about to forget them, according to how well you know the information in each card. It is a very sophisticated algorythm, and it is very efficent. for those who may think, "that´s not learning, thats just memorizing", well to them I say: that´s learning!

I like the ease of creating my own content.

Uso multiplataforma: puedo escribir tarjetas de estudio en la computadora y luego estudiarlas en mi teléfono Calificaciones de confianza: poder calificar una tarjeta según la confianza y que las menos confiables se repitan con más frecuencia es muy útil
