Before/After: Streamline Health’s Appointment App Redesign — A UX Metrics Deep Dive

Design · 6 min read

Streamline Health's mobile appointment app had high no-show and cancellation rates, and patient interviews revealed confusion about what constituted a confirmed booking. The original flow hid the confirmation step behind a modal and used technical jargon for preparation instructions. The redesign aimed to make commitments explicit and lower the cost of rescheduling.

Design changes included a persistent booking card with clear status labels, calmer microcopy for prep instructions, and a proactive rescheduling CTA that allowed patients to pick new times without canceling. The team also added a short 'what to expect' checklist and integrated SMS reminders with one-tap check-ins. They tested variations of confirmation phrasing and reminder cadence using a sequential rollout.

After six weeks, confirmed attendance rose by 18%, last-minute cancellations fell by 26%, and the average lead time for reschedules increased (fewer urgent changes). Clinicians reported smoother schedules and fewer administrative follow-ups. The case shows how visibility and low-friction change paths can materially affect operational metrics in service-oriented startups.
