The situation

Patients booked by phone, during clinic hours only, and reception spent most of the morning confirming appointments one call at a time. A third of Merren’s list lives west of the city with no reliable connection at home, which ruled out anything web-only. Everything touching records had to clear their existing clinical governance review before a line of it shipped.

What we built

01Offline-first record storeLocal encrypted store with conflict-aware sync, so appointments and notes are readable with no signal and reconcile when the device reconnects.
02Secure messagingThreaded clinician messaging with read receipts, retention rules and escalation to the on-call line.
03Pharmacy pickupPrescription status and a four-character collection code, replacing the pickup phone queue.
04Release pipelineAutomated builds, staged rollouts and crash reporting across both stores, handed to Merren’s team in week 17.

How it went

The app shipped to both stores in week 16 and passed 60,000 installs inside a year. Missed appointments fell roughly 30% once reminders moved in-app. Reception phone volume dropped far enough that Merren redeployed two staff to patient intake.

Our patients out in Connemara can read their appointment letter with no signal at all. That one detail decided the project.
