Mr Twidle can thank his daughter Maria Johnston who was inspired to develop SmartCare by her parents' situation. "It enables caregivers and patients to live more independently," she said.
The other major innovation that helped Mr Twidle was SmartCare's "reminders" section in which he can bring up all his daily tasks, including appointments and taking his pills and insulin. He then ticks them off by a touch of his finger on the screen.
And if an emergency occurred while Mr Twidle was out on his mobility scooter or at home alone, he can trigger an alert straight through to family members by touching the "emergency" section of his phone.
Another feature of SmartCare was that his smartphone was always connected to family members who could log on via their smartphones, tablets or laptops to see where he was on the Google map and whether he had taken his pills.
His married daughter, who holds a degree in information technology, launched SmartCare yesterday. While the system was still in its early days, it provided enough functions to take the simplified system to the market.
She said SmartCare made the small stuff in life possible for people with mild cognitive impairment.
"Things that you and I may take for granted."
It was not designed for people with advanced Alzheimers.
The idea came to her about 18 months ago but things did not really start to happen until she attended a business start-up weekend in Tauranga. Since then she has formed a team, developed the product and incorporated the company.
"There has been a lot of hard work."
Details of the system can be found on the company website smartcarehq.com
