My father has dementia and lives at home with my mother. We were looking for something that didn't look like a "Care" watch, but that would allow us to keep track of him if he did wander, and allows basic functionality. I am more than impressed, this watch allows him to answer calls in a very simple way (automatically answers if he lifted his arm to check what the vibration was), and we can choose a very plain background digital clock (which also has a date!). He isn't able to independently make a call or use SOS as his dementia is quite advanced, but I imagine that this basic function would be easily used by people who are less effected. I set up the app on my phone and my mothers, so we both receive an alert if he's left the "safe zone" of the house when mum's gone out. It also allows us to see how much he has moved around in the day, with the step counter. I love that the vibration alert brings his attention to calls and allows him to respond. I am an Occupational Therapist and will be recommending this watch to others who are looking for a simple device that allows calls, limits other functions, and is wearable. We are currently trying to find a cheaper pre-paid SIM with data than is offered by Telstra ($30 a month that expires is quite high but I understand Aldi may offer a cheaper alternative under Telstra). Still looking into this, so looking at a max cost (after payment of the watch) of $36 per month which includes the app cost. Still not too bad for increased peace of mind. Just make sure it's taken off for showers (perfect time to charge it).
