Wear & Care
A smart diaper sensor that tells care staff when it is time to change.
Wear & Care makes a connected diaper sensor for care homes. The sensor detects when a diaper needs changing and notifies care staff on their phone, so residents are changed when they need it, not on a fixed round.

What was the challenge?
A care home at 3 a.m. is the real test environment. The alert has to reach the right carer, on the right shift, without adding noise. The platform also has to fit the municipality’s identity system and the care home’s existing workflows.

What did bon.do build for Wear & Care?
We built the sensor ingress, .NET 10 backend, Angular portal and Flutter carer app as one system. The backend uses PostgreSQL, Wolverine, Redis, Azure Service Bus and NATS JetStream, and runs in Kubernetes. We integrated KOMBIT and NemLog-in/MitID through Keycloak, with role-based access scoped to the care home. Alerts go out by push, SMS and SignalR, and every event is logged.
Device software
Telemetry, battery, pairing and offline behaviour, with a config channel back to the device.
Cloud backend
Links each sensor to a resident and room, routes alerts to the right shift, and keeps a log of every change.
Carer app
A ward overview and alerts designed for a busy shift, readable at a glance, at night, with one hand.

One glance: who needs you, and where.
The status overview shows every resident at a glance: who needs changing, whose sensor is low on battery, and who has no data, so the next change is always clear.

Inside the product
One resident, with the day’s events in order. Real app, example data. Login with email or the municipal KOMBIT login. Real app.
What was the result?
The platform is live in Danish care homes, with the carer app in the App Store and Google Play. The sensor data, resident, room and shift stay connected, and the ward overview gives staff one place to see who needs attention.
“Bon.do assisted us all the way from design to finished backend and frontend of a new medical IoT device. They understand both MDR and GDPR as well as hardware interaction.”
