Lagun breathing mark

The calm before the appointment.

Lagun helps older adults arrive prepared, speak clearly, and leave with a record of what was said, with a trusted companion by their side.

A working prototype for Taiwan's very short clinic visits, built to be studied in the field without claiming field results yet.

Journeys

Three readers, one honest product story

Each audience sees the same evidence base, but the emphasis changes.

Your parent may have five minutes with the doctor. Lagun helps the visit start with what matters and end with something the family can understand.

The service is non-diagnostic and does not promise continuous location tracking. It supports preparation, communication, and accountable companion handoff.

Care principles in practice

A campfire is not about making everyone the same. It is about letting different people safely gather around the same question.

Awareness

01

Focus on what patients, families, and companions must notice in those five minutes.

Responsibility

02

Diagnosis stays outside the product boundary — by design, not disclaimer.

Coexistence

03

Data access is visible and revocable. The patient can always see who accessed their record.

Care Commitments

  • Record, do not diagnose.
  • Prepare, do not prescribe.
  • Support the companion, do not replace clinical judgement.
  • Use events for accountability, not continuous location tracking.
  • Keep private records behind login-gated systems.
Booking

Only inquiry details are sent to the new public endpoint. Lagun PWA health notes are not submitted.
