From RunKeeper to Lyft to FlightTonight, there are plenty of mobile apps that are practical, functional, and just plain good ideas.
There are also addictive games that, while not my cup of tea, keep millions of people transfixed on otherwise dreary commutes in and out of work.
And then there's a bunch of weird apps that make you go "hmmm." Whether they seem hilariously niche, totally useless, or you're just shocked there's a market for them, the apps in this post might make you curious enough to download.
(And you can do so guilt-free -- because they don't cost a cent. Enjoy.)
Wondering whether now is the time to relieve yourself of that red slushy you just sucked down? Run Pee will tell you when you can run and pee without missing anything big in the movie. Incredibly weird. Incredibly useful.
