Most-used app: MessageMe.“It’s a group-texting app and is now my primary way of communicating with my friends, whether for chatting or for coordinating meeting up. MessageMe makes it super simple to create named groups, share images, share locations, and doodle on images. I have groups for Brunch, Basketball, Hipmunk, Bros, etc. It’s largely replaced both Facebook and e-mail for social communication.”

Last app used: Calendar. “I use the default iOS calendar app. I’ve tried others, but it’s my favorite, and I can’t live without it. If it’s not on my calendar, I’m not aware of it, whatever it is.”

Currently obsessed with: PayByPhone. “It allows me to pay for parking meters and feed them remotely. It’s super convenient, since I don’t keep quarters with me.”

Last download: GIF Shop. “I needed to make a GIF of my friend looking ridiculous. I heard about it from a friend who often makes GIFs of friends looking ridiculous.”

Most surprising app on his home screen: Gmail. “Lots of people hate on it, but the built-in Mail app on iOS is terrible, and the Gmail one isn’t bad.”

Guiltiest pleasure: Reddit. “I only read it in [Reddit client] AlienBlue. I rarely go to the actual Web site anymore. I have to be really careful when I open it, because I know I can lose an entire hour before I know it.”

__Favorite mobile game:__Spaceteam. “A friend of mine introduced me to it at dinner one night. Basically, you team up with friends locally over Bluetooth or Wi-Fi and have to shout instructions at each other to operate a spaceship. It’s hilarious. Always a good time.”

Clean inbox? No. “I have about 10 unread messages in both my personal and work account. I could go on a long rant about how much I despise e-mail. I wish it was more socially acceptable to ignore people.”

Text or call? Text. “I haven’t placed any calls today. I’m rarely in a position where I can actually answer my phone without being rude to someone else. Sometimes I look back and realize it’s been weeks since I’ve actually been alone. With texting, I can at least get a sense of what’s going on without interrupting what I’m doing.”

__Remaining battery:__100 percent. “I charge it at work constantly and only sometimes at night. I’ve only had it die once, and that was when I was on vacation in Russia recently and was awake for way too long.”
