Meet the Alpha Track Go Play: a smart wearable device designed for parents who want to keep an eye on their children. It features GMS cellular connectivity, push button calling, GPS with LBS positioning, and up to 4-day battery life. The companion app lets you see your device, define geo-fences, receive important alerts, and more.
The developers also have a device for seniors in Go Beyond. It has a similar set of features but uses a G-Force sensor for fall detection. You can find out more on Indiegogo.
