Make yourself happier by reminding yourself you're going to die

That's the ironic promise of a smartphone app called WeCroak, which pings your phone five times a day, every day, reminding you that you're going to die. Its creators say the app (which was inspired by a Bhutanese folk saying "To be a happy person, one must contemplate death five times daily") helps you to stop sweating the small stuff. It's also a nudge to stop wasting time on things you don't value and paying attention to what has meaning or will bring happiness
