Patient data stayed out of the apps
The apps are HIPAA regulated, and the design goal was that a phone in a relative's hand
should never be holding protected health information. Room and identity handling was
built so patient information was not passed around on the back end, and the client app
works without ever needing to know who the patient is.
Two native apps, not one cross-platform one
iOS and Android were each built natively, the iOS side in Swift and UIKit. Real-time
video, background call delivery, and platform notification behavior are the areas where
native access matters most, and both apps had to behave like a phone call rather than
like a web page.
Notifications that a muted phone still hears
A missed call from a hospital is not the same as a missed marketing push. The iOS app
requests critical alerts, an entitlement that lets a notification sound through silent
mode and Do Not Disturb, alongside the standard notification permission.
Onboarding measured in seconds
The person installing this app is often a family member who just got difficult news.
Registration is a name and a phone number, with no password and no account recovery
path to get stuck in, and the app drops straight onto the call screen afterwards.
