Droplr
Our sister site, The Sweet Setup, recently picked Droplr as their favorite file sharing service. While there are a lot of great options, Droplr was their favorite. I’ve used Droplr for a few years now, and it is one of my most used apps. With the ability to share PDFs, screen recordings, and other file types, it’s a great useful tool to have on your Mac. One of my most used functions is annotating over screen shots right from within the app.
Droplr is a paid only service with pricing that starts a $4.99 per month. If this is the type of app that you use daily, then you’ll get more than your investment back out in productivity.
