Day-to-day use
Patient roster, push notifications, alert response, device status, and biometric unlock.
The five tabs
The mobile app is organized as five tabs across the bottom of the screen:
| Tab | What it shows |
|---|---|
| Home | Your patient roster and today's snapshot. |
| Alerts | Open alerts that need a response. |
| Devices | Device inventory and status. |
| History | Recent readings and your activity log. |
| Profile | Settings, notification preferences, and sign-out. |
Patient roster (Home tab)
The Home tab opens to your assigned patients, sorted by who needs attention most. Each patient card shows:
- Name, MRN, and a compact list of their active vital types
- The most recent reading and how long ago it was taken
- A status pill: OK, Trending, or Alert
- A small chevron. Tap to open the patient detail screen
You can pull-down to refresh and search by name from the top bar. If your practice uses care-team assignments, the roster scopes to your patients by default; toggle Show all to see everyone.
Alerts and push notifications
Alerts are the fastest way to know a patient needs you.
When a reading crosses a threshold, the backend creates an alert and sends a push notification to every clinician on that patient's care team. Tap the notification to jump straight to the alert.
Each alert shows:
- The triggering vital and value (e.g., BP 168/102 mmHg)
- The threshold that was breached and the patient-specific limits
- Recent readings for context
- The patient's name, age, and a one-tap call button
Responding to an alert:
Acknowledging an alert is not the same as resolving it. Acknowledge tells your team "I've got this." Resolve closes the alert and stops further notifications.
Notification preferences
Open Profile → Notifications to fine-tune what buzzes your phone:
- Vital types: choose which vitals you want alerts for (BP, glucose, weight, SpO₂, heart rate)
- Severity: get only critical alerts, or all of them
- Quiet hours: silence non-critical alerts overnight
- Digest mode: bundle non-critical alerts into a single morning summary
Critical alerts (like a hypertensive crisis or severe hypoglycemia) override quiet hours. Vantrexia chooses what counts as "critical" based on AHA / ADA / Mayo Clinic / WHO thresholds. See the medical disclaimer in Profile → About.
Device status
The Devices tab mirrors what you'd see in the staff portal but optimized for quick lookups when a patient calls:
- Search by patient name, device model, or serial number
- Each row shows the device, the patient it's assigned to, and the last time it transmitted a reading
- A status badge (Active, Ready, Suspended, or Inactive) tells you if the SIM is live
- Tap any device to see its full timeline and recent readings
This is the screen to pull up when a patient says "my scale isn't working." If you see it transmitting fine, the issue is usually patient-side (battery, Bluetooth pairing, plug it in for an hour).
Biometric unlock
The first time you sign in, Vantrexia asks for permission to use Face ID or Touch ID. If you allow it, future opens skip the password entirely. Just look at the phone or rest your finger.
To enable or disable it later: Profile → Security → Biometric unlock.
Biometric unlock is per-device. If your phone is shared (it shouldn't be), turn this off. Anyone whose face or fingerprint is enrolled in iOS will be able to open the app.
Working offline
The app caches the last 24 hours of patient data so you can still review readings on a flaky cell signal. Anything you tap in the roster while offline loads from cache and shows a small Offline banner at the top. As soon as you reconnect, fresh data syncs in the background.
You cannot acknowledge or resolve alerts while offline. Those actions need to hit the server in real time. The buttons disable until you're back online.
A note on PHI on screen
The app shows patient names and vitals. That's protected health information. iOS automatically blurs the app preview in the task switcher. Still, treat the phone like you would a paper chart: don't leave it unlocked on a coffee shop table.
