Dramatic growth in mental-health apps has created a risky industry

WHEN CAROLINA ESCUDERO was severely depressed, going to a therapist’s office became hard to face. So she joined BetterHelp, a popular therapy app. She paid $65 each week but spent most of her time waiting for her assigned counsellor to respond. She got two responses in a month. “It was like texting an acquaintance who has no idea how to deal with mental illness,” she says. BetterHelp says its service does not claim to operate around the clock, all its therapists have advanced degrees and “thousands of hours of hands-on clinical work”, and users are able easily to switch them if scheduling is hard.
