Summary

This study tested whether a smartphone app designed for people with serious mental illness can help them quit smoking better than standard methods. Researchers enrolled 343 adults with conditions like bipolar disorder or schizophrenia who wanted to quit. Participants used either the special app or usual care, and success was measured by not smoking for at least 7 days after 6 months.
