Once again, AppyFridays has three great Mac apps that are this time free for the weekend:
Diagrammmix (reg price: $19.99)
Simple and efficient tool to build attractive diagrams, using unique styles and rich features.
Marko (Reg price – $1.99)
Easy to use app to preview Markdown documents and convert to HTML or PDF. Marko can be used side-by-side with a favourite text editor to preview Markdown documents while writing.
Singlemizer (Reg price – $9.99)
Cool app to find and manage duplicate files, photos, and directories on a Mac easily. Unlike most duplicates eliminators, Singlemizer zeroes in on the file’s contents.
