9 Apps to Help Manage Stress

Amid the world's high levels of anxiety and stress, the mindfulness space is becoming one of the most crowded and well-funded in the app ecosystem. Two of the most well-known are Calm, which recently was valued at $1 billion, and L.A.-based Headspace, which announced in early February that it had raised $93 million in a Series C funding round. Among Hollywood's favorites are these eight apps, which include everything from a gratitude platform (with guides by George Takei) and a heartbeat-powered virtual-reality world to a personalized way to benefit from cognitive behavioral therapy.
