The chief executive of family tracking app Life360 says problems looking after his own mother have led the company to develop a device for monitoring elderly parents who are at risk of falling or wandering off.

Chris Hulls is the chief executive and co-founder of Life360, an ASX-listed Silicon Valley tech company that created a family safety and location-sharing app with 80 million users worldwide. It has 2.7 million users in Australia and New Zealand, and lets parents keep track of their kids on a smartphone app.
