Mike Wehner writes: “For a teen struggling with depression and other mood disorders it can be hard to admit you need help, or even understand what the problem is. Researchers at Rutgers are working on a smartphone app that can make tracking troubling patterns easier for parents, and hopefully help in the fight against teen suicide.”

He adds: “The app has some limitations, and in order for it to work as intended, the user can’t forget their phone, frequently turn it off, or refuse to voice their feelings in the daily diary. In short, the app, which is still in development, may face an uphill battle to get teens to actually use it.”
