What are some good devices to help seniors who live alone?

• Medical Alert Devices
The most favoured medical alert device is Life Alert, but it is certainly not the only one available.                                                     
• Invisawear Smart Jewelry
This fantastic product is a piece of jewelry that can be a necklace or a bracelet. You can use an app on your phone to set it up and choose up to 5 people to be warned when and if you use it. One additional helpful item would be a magnetic clasp for the Invisawear necklace. This makes it easier to put on and take off for anyone struggling with small jewelry clasps. 
• Medical Alert Watches
The Freedom Guardian watch is one of several different medical alert devices that can be worn as a watch. It has GPS tracking capabilities, reminders, and more. 
• LifeFone Medical Alarm
It’s very similar to Life Alert – an accredited medical alert provider with lots of equipment you can use to protect yourself or a loved one when and if an emergency occurs.
• Amazon’s Alexa Device
You may not consider Alexa as a medical device. Still, it provides the ability to call 911 and contact several of your friends or family members in case of an emergency. It’s best used for emergencies within your home.
