About Project
LungPass pairs a smart stethoscope with an app so families and doctors can track lung health, spot danger early, and decide when a visit is needed.
Challenge
Early MVP was off-brand and too clinical for families.
Multi-screen exam flow confused users; 60 % dropped before recording.
Brand lacked a clear, reassuring voice for non-tech patients.
