Happify
While the company’s ethos of “training your brain to be happier” sounds like something a New Age guru might preach at you, the methods behind this app are at least backed by some science. Using a series of methods intended to induce self-reflection, perspective and serenity, the app claims to be able to make you happier. It didn't make us feel much different, but then again we're miserable grumps. Obviously, the app is no replacement for professional therapy. (iOS, Android. ~$15/month for full access)
