Getting Started
Sworddrill requires no download or account. There are, however, a few good places to start depending on your intent.
If you are a quizzer, probably the most helpful tool for you will be flashcards. The guide has an in depth section describing it and its settings in great detail here. It has several different modes, each allowing you to study the material in a different way.
Second, if you are a coach, the most useful tool for you will be the search tool. As described in the explanation for it, it allows you to search both current and past materials with ease, while also giving you a large amount of control over how it searches and sorts the material. It comes with built-in highlighting and underlining. It especially has been designed to be very fast and efficient, so even on mobile devices, it should still be very responsive.
