I find that Anki, by showing up the cards at certain (optimised) intervals, delivers distributed practice. Out of the efficient learning methods as evaluated by this paper: "Improving Students’ Learning With Effective Learning Techniques: Promising Directions From Cognitive and Educational Psychology" [1] (scroll to Table 4 for results) Anki delivers both distributed practice and practice testing in a very natural way.
