I use simple, effective tools that look great and work with ease. Preferably Beta versions because I like new.
Apple OSX El Capitan
Currently running a dark themed El Capital with a nice wallpaper.
I use Things for OSX/iOS for personal task management.
We use Jira for project management. Great tool for project management.
Currently using Slack for chatting on team and 1-on-1 basis with our team.
For email I use Airmail.
I use Ulysses for OSX/iOS for simple writing and blogging.
I use SketchApp to design user interfaces, logo's and other visual documents.
I use Atom.io for writing code.
