Tinder

On iTunes at: itunes.apple.com

Price: Free

If you're single and looking for friends, hookups, or whatever else, feel free to download the app. However, you'd be amazed at just how many people (in relationships) have this app on their phone.

It's never a good idea - the app makes you sign in through Facebook and chances are, you'll run into someone on the app with mutual friends as you. It's only a matter of time before someone gets caught! If you have a significant other, this app is not for you.

Unfortunately, there are so many other apps that are killing romantic relationships. Has yours been ruined by one?
