I am not an early adopter. Actually, I’m pretty adverse to change and am often the last one to try a new app or service (I joined Instagram months after my friends because I didn't see the need to take even more photographs. Now I'm pretty obsessed). However, when there’s a piece of technology that can make my life easier, I'm usually open to giving it a try. Here's the tech apps and services that help manage my personal and professional life. Also, most of them are free and have a desktop and mobile version, so you can move between devices seamlessly.
