Two Dots -- I am completely addicted to this puzzle game on my iPhone. I honestly don't know whether to tell you to clear your schedule and start playing, or run screaming for the hills. The game is free, but there are in-app purchases that can help you through frustrating levels...thus, I have spent more money on this game than I care to admit to anyone. The sound and graphics are great, too.
Humans of New York -- A collection of real stories from real people seen on the streets of New York. If you've never looked at HONY, as it's known, you'll end up binging on it for a couple of hours. The stories can be funny, heartbreaking, and unbelievable. I very highly recommend scrolling through the archives to August/September when the photographer went on a trip with the United Nations.
