How Dementia Tracking Watches Work (and How They Help Prevent Wandering)

Dementia tracking watches are wearable devices designed to help families and carers keep vulnerable loved ones safe, particularly when there is a risk of wandering or getting lost. They combine location tracking, mobile connectivity, and alert features into a simple device that can be worn every day.

Unlike smartphones, which can be forgotten or misplaced, dementia tracking watches are designed to stay on the wearer’s wrist and work quietly in the background. This makes them especially useful for people living with Alzheimer’s disease or other forms of dementia.

What Is a Dementia Tracking Watch?

A dementia tracking watch is a wearable safety device that allows carers to see the wearer’s location and receive alerts if something unusual happens. Most models are designed specifically for older adults and people with cognitive impairment, prioritising simplicity, reliability, and ease of use.

These watches typically include:

• GPS location tracking
• Mobile network connectivity (rather than relying on home WiFi)
• Alerts for wandering or leaving safe areas
• An emergency call or alarm function

The goal is not surveillance, but reassurance. Dementia tracking watches help families respond quickly if a loved one becomes disoriented or lost.

How Location Tracking Works

Dementia tracking watches use GPS and mobile network connectivity to send location updates to a secure system that carers can access through an app or web dashboard. This allows families to check a loved one’s location in near real time.

Location accuracy can vary depending on surroundings, signal strength, and whether the wearer is indoors or outdoors, but the system is designed to provide a clear and useful indication of where someone is.

What Happens If Someone Wanders?

Wandering is common in people living with dementia and Alzheimer’s disease, and it can happen even in familiar places. Dementia tracking watches are designed to detect and respond to this risk.

Many systems allow carers to set up safe zones, sometimes called geofences. These are virtual boundaries around places such as the home, a care facility, or a familiar neighbourhood.

If the wearer moves outside one of these safe zones:

1. The watch detects the change in location
2. An alert is sent to the carer or family member
3. The carer can check the live location and decide what to do next

You can learn more about this feature in our guide to geofencing for dementia care.

Why Watches Work Better Than Phones for Dementia Care

Smartphones are not always suitable for people with dementia or Alzheimer’s disease. They can be forgotten, turned off, or left behind, and many people find them confusing to use as their condition progresses.

Dementia tracking watches are designed with these challenges in mind:

• They are worn on the wrist, reducing the chance of being misplaced
• Many models use secure or lockable straps to prevent removal
• There are fewer buttons and distractions
• Alerts and tracking work automatically without user input

This makes watches a more reliable option for continuous safety monitoring, particularly for people in the middle to later stages of Alzheimer’s or dementia.

Keeping the Watch Secured: Lockable Straps and Non-Removable Designs

One practical challenge with any wearable safety device is keeping it on the wearer’s wrist. People with dementia or Alzheimer’s disease may not understand why they are wearing the watch, and may try to remove it, particularly during moments of confusion or distress.

A lockable watch strap addresses this directly. It uses a fastening mechanism that cannot be undone without a small tool, which means the wearer cannot remove the watch themselves. Carers retain full control over fitting and removal.

This is especially useful for people who are in the habit of taking off jewellery or wristwear, or for those whose wandering risk is high. A watch that stays on the wrist is a watch that can do its job.

Emergency Alerts and Carer Notifications

In addition to location tracking, the Perfect Alert dementia tracking watch includes a range of emergency alert features designed to get help to the wearer as quickly as possible.

The watch supports several types of alert:

• SOS button: the wearer can press and hold a dedicated button to immediately contact carers or a nominated phone number
• Geofence breach alerts: carers are notified automatically if the wearer leaves a pre-set safe zone
• Two-way calling: carers can speak directly with the wearer through the watch, without the wearer needing to navigate a phone interface

When an alert is triggered, the wearer’s current location is shared at the same time. Carers receive a notification via the app and can see exactly where the wearer is, making it possible to respond quickly and confidently.

This is particularly valuable in situations involving Alzheimer’s disease, where the person may become frightened or disoriented and be unable to communicate their whereabouts.

Accuracy and Limitations: How the Perfect Alert Watch Compares

All GPS tracking devices face similar technical challenges, and it is worth understanding them. What matters is how well a device is designed to work around them.

Signal coverage is the most common concern. The Perfect Alert watch uses a quad-network SIM that connects to EE, Three, O2, and Vodafone. Rather than locking to a single network, it automatically roams to whichever network has the strongest signal in a given location. This gives it significantly broader coverage than most consumer GPS devices, and makes it more reliable in rural areas or when the wearer travels away from home.

Location precision is the second concern, particularly if a vulnerable person is in an unfamiliar area. The Perfect Alert watch integrates What3Words, a system that divides the entire world into 3×3 metre squares and assigns each one a unique three-word address. When an alert is triggered, carers receive not just a map pin, but a precise What3Words location that can be shared directly with emergency services if needed.

Battery life is a genuine practical issue for wearable devices. The Perfect Alert watch holds its charge for four to five days on a single charge, which means most wearers can go several days between charges without the device running flat overnight or during a day out.

Used alongside regular routines, supervision, and care planning, the watch can significantly reduce risk and provide lasting peace of mind.

How Dementia Tracking Watches Help Families

For families and carers, the biggest benefit of a dementia tracking watch is reassurance. Knowing where a loved one is, and being alerted quickly if something goes wrong, can transform the day-to-day experience of caring for someone with dementia or Alzheimer’s disease.

Carers who previously felt unable to leave the house, or who spent long periods anxious about a loved one’s whereabouts, often describe these devices as giving them their lives back. The ability to check a location in seconds, or to receive an instant alert if something changes, removes a significant amount of constant background worry.

For the person wearing the watch, there is a benefit too. When families feel confident in the safety net in place, they are more willing to allow their loved one a degree of independence. That independence, even in small doses, has a meaningful impact on quality of life and dignity for someone living with dementia.

Many carers use these devices as part of a broader approach to dementia care, alongside home adaptations, community support, and medical guidance. They do not replace care, but they fill a gap that nothing else quite covers.

Choosing the Right Dementia Tracking Watch

Not all dementia tracking watches offer the same features or reliability. When choosing a device, it is important to consider:

• Ease of use for the wearer
• Battery life and charging routine
• Accuracy of location tracking and network coverage
• Quality of alerts and notifications
• Whether a lockable or secure strap is available
• Suitability for people with Alzheimer’s disease or other forms of dementia

Frequently Asked Questions About Dementia Tracking Watches

How does a dementia tracking watch work?

A dementia tracking watch uses GPS and mobile network connectivity to send regular location updates to carers. If the wearer moves outside a pre-defined safe area or triggers an alert, notifications are sent so carers can respond quickly.

Are dementia tracking watches accurate?

Dementia tracking watches are generally accurate outdoors where GPS signal is strong. Accuracy can vary indoors or in areas with poor signal, which is why these devices should be seen as a safety aid rather than a guarantee.

What happens if someone with dementia wanders?

If the wearer leaves a safe zone, the watch detects the change in location and sends an alert to carers. Carers can then view the live location and go to find the person, or contact emergency services with the location details.

Can the watch be used by someone with Alzheimer’s disease?

Yes. Dementia tracking watches are suitable for people with Alzheimer’s disease and other forms of dementia. The watch operates in the background without requiring the wearer to do anything, and a lockable strap can be used if there is a risk of the person removing it.

Are dementia tracking watches suitable for people with Alzheimer’s disease?

Yes. Dementia tracking watches are commonly used by people with Alzheimer’s disease and other forms of dementia, particularly when there is a risk of wandering or disorientation.

Do dementia tracking watches replace supervision or care?

No. Dementia tracking watches are designed to support carers, not replace supervision or care. They work best when used alongside regular routines, supervision, and wider dementia care planning.
