Adaptive review is another point to weigh, along with source formats for bringing material in and export options for taking it elsewhere. Mobile apps may matter if you study across devices; the listed free plan and paid-from details offer cost comparisons. The ranking starts with Gizmo, Knowt, and StudyGlen, with RemNote and Quizlet also among the early entries. Check these criteria against the material you want to study and the ways you prefer to review it.
