If you've been looking for a tactful way to tell that buddy about his bad breath or unruly nose hairs, there's now an app for that. The D.C.-based barbershop and men's store Grooming Lounge has just come out with Send a Tip, an iTunes application that lets you send a friendly and anonymous alert to someone in dire need of assistance. "Men who have these issues need to know they have them and how to correct them," says Michael Gilman, the cofounder of Grooming Lounge. "We're providing a safe environment for people to be that all-important nose-hair whistle-blower." Download the free app from the iTunes store now.
