Bryan Timlin always carries an iPhone and an Android phone.

The 57-year-old is an app and graphic designer with a Michigan company calledOptHub, but he doesn’t carry two phones for work. He carries the iPhone because that’s what he likes, and he carries the Android because it’s what he needs.

The Android phone monitors his behavior. Five years ago, Timlin was diagnosed with rapid-cycling bipolar disorder, a mental illness characterized by four or more manic or depressive episodes a year. Some episodes, he says, can last as long as eight weeks. “Being bipolar is like jumping out of an airplane knowing you don’t have a parachute on,” he says. “You know you’re going to be hurt, but the high is so euphoric that it’s worth the risk. You can deal with the consequences later.” With his Android phone, he hopes to deal with these moments in other ways.
