It's 2016 -- if you're not texting, you've fallen behind. I text my family, I get appointment reminders via text, and text is being used for 2-factor authentication.
At my company there are several different communications apps, from Yahoo Messenger, to Slack, to HipChat. They each work well, but only texting is guaranteed to reach the person I want to talk to.
With that being said, texting can be difficult from my phone if I have multiple conversations going on, or I have a lot to share. Fortunately, I've found a great solution. Whenever I'm at a computer, PC and Mac (I have both), I can use MightyText instead.
MightyText works with Android phones and Google Chrome browser. Not only can I type faster using MightText, I get notices from my phone on my computer screen. I no longer need to take my phone out of my pocket to see alerts or respond to text messages.
It also as the added benefit that I can easily attach any image that I can access from my computer. There's also an integration with Gmail, if you want to work within the Gmail interface (over having its own tab).
MightyText is on my short-list of must have apps.
