Here’s a list of some of the tools I use on a daily basis:
Omnifocus – I am scatter-brained. Omnifocus helps me hold everything together. This is the essential cog in my workflow, and has greatly increased my productivity while decreasing my stress levels. Location-based contexts are incredible, BTW.
Text Expander – Text Expander does exactly what it says (expands text). It’s a simple concept, but will save you hundreds of hours if you use it consistently. It even supports fill-in snippets and radio buttons, and the iOS versions works with my favorite iOS app, Drafts.
Fantastical – I was introduced to Fantastical in a bundle, but it is easily my favorite calendar app. It’s design is absolutely stunning, and the natural language recognition can’t be beat. The iOS version in particular is head and shoulders above everything else on the market IMHO.
1Password – 1Password is an application I don’t think I could live without anymore. It allows you to store all your internet passwords (and a lot more) securely and autofills them so you never have to remember a password. Ever.
nvALT – Developed by the incomparable Brett Terpstra, nvALT is my scratchpad of choice. It’s a free, lightweight application that supports Markdown and has lightning fast search. It also syncs with Simplenote on iOS (if you take the time to set it up through Dropbox).
Day One – I’m starting to make journaling a habit, and Day One is far and away the best journaling platform on Mac and iOS. It supports Markdown (which is essential) and has lightning-fast sync via either iCloud or Dropbox, whichever suits your fancy.
f.lux – Man was never meant to stare at a screen emitting blue light at all hours of the day (and night), and f.lux changes the color of the light in accordance with your local sunrise and sunset so as not to interrupt your body’s natural rhythm.
Hazel – I’m almost ashamed of the limited level at which I use Hazel, but it’s a valuable tool none the less. The guys & gals over at Mac power Users have some crazy Hazel setups that I aspire to implementing someday.
