Before Stacks, everything I did was through the browser, but I craved an offline app that would work as well as Trello or Basecamp. Now I have it! I can go off grid with Stacks and still keep track of my workload easily. It also has a geo feature I've not seen elsewhere - you can set a real world location for your tasks and see them on a map (pro only). I haven't made great use of this yet but I imagine it's going to come in handy in future.
