The challenge

A mental health clinic running a panic-attack hotline was overwhelmed during the COVID-19 lockdowns. It had very few agents and nothing to offer callers once the lines were busy.

What we built

  • A cross-platform app that works fully offline, designed around the clinic's own exercises
  • Guided audio sessions streamed from a bandwidth-efficient HLS server
  • Subscriptions and a simple, calm interface built for people under stress

Built with
