From the developer:
mooDex fills the gap left by Casady & Greene, Inc.'s QuickDEX. It opens and saves QuickDEX files, displaying them similarly to QuickDEX.
Like a box of index cards, mooDex can be used for anything from addresses to recipes. The simplicity of mooDex is what gives it it's elegance.
The interface in mooDex is somewhat more intuitive than QuickDEX, adding OS X's user friendly interface elements.
