MemoDroid is my recent work on Android platform.

It is a tool that can help you memorizing things, including words, idioms, laws, learning materials... anything that you don't want to forget. And it enables you to utilize piecemeal time for this task.

The theory is simple. We know that we need to repeat memorized things every time and often, and the newer the item is, the more often we need to repeat it. What MemoDroid does here is to take over the repetition process and help you manage the item's repeat period.

Site update: new look of menu system

The menu display has been changed from a tree-like menu hierarchy to a flat menu that rely on background color to identify their levels while the DHTML feature is still intact.

The more bright the background is, the deeper the item belongs to.

Underline indicates that this item has sub-menu. Single click on it will expand its sub-menu, while double click or a single click on the italic item with the same name from its sub-menu will bring you to the location this item points.

The item with a red box infront of it is the current item.
