The companion app provides the following features:

• scan the messages to the message center of the Android OS
• run as service in the background
• make the relevant message sources configurable for message scan
• configure the Watchy as message consumer

Build and Deployment

Features under development

Android Smart Lock support

The Watchy should be used as Trusted device for Android Smart Lock functionality.

The Watchy must be paired / bonded to the mobile device (new item in Watchy menu).

Watchy will advertise via BLE to support Smart Lock unlock.

Location discovery: If mobile device is in roaming zone, IP address is still received from home mobile service provider, which results in home weather report on watch face.
