DropTask help me to get things done with help of visualization. You can select various views on your tasks - like a Canvas, Calendar, Workflow and great one Planner (that was introduced in last update). For each task you can add various additional information and context like tags, comments, uploads, cover imager, efforts, priorities.
For me the game changer is mobile application that provide great user experience and it´s handy companion to desktop app and Canvas view - that is something I cannot find with others products on the market.
The additional value is provided with integration with other applications like iMindMap, Evernote, Dropbox, Google Drive. Review collected by and hosted on G2.com.
