GPS and dementia trackers: choosing one safely for older adults

Later-life checks before you choose

For an older adult, the practical test is whether the device fits hearing, vision, memory, and the daily routine. A system that is hard to wear, hard to charge, or confusing to use is unlikely to be ready when it is needed.

Getting lost can happen before a formal diagnosis. A tracker should support agreed boundaries and a care plan; it should not be treated as a substitute for supervision.

Involve the person who will use the alarm in the decision. If memory or mobility has changed recently, review the plan with a clinician, care professional, or local service rather than relying on a device alone.

• Check whether the button is easy to see, feel, and press.
• Ask how the device reminds the user to charge it.
• Confirm what the responder does if the user cannot speak or hear.
• Review the plan after a hospital stay or a change in medication.
• Keep a written contact and medical-information list with the monitoring centre.

A tracker is not a personal alarm

A GPS tracker reports a location. A personal alarm lets the wearer call a monitoring centre or family contact. Some devices combine both, but the functions solve different problems. A tracker can help you find someone who has walked away from home; an alarm can help someone who has fallen and cannot get up.

If the main concern is getting help after an emergency, start with a personal alarm. If the main concern is finding someone who may become disoriented, a tracker may be appropriate. Many families need a plan that includes both, plus a search procedure for the people involved.

In later life, a guide like this is most useful when it is read alongside the person's own routine and care arrangements. A device or feature that sounds reassuring on paper can add work if it is difficult to charge, uncomfortable to wear, or unclear to the people responding.

Consent, capacity, and dignity

Tracking a person without their knowledge can damage trust and may be inappropriate. Where someone has capacity, explain what the device does, who can see the location, and when it will be used. If memory or decision-making is changing, involve a clinician or care professional and follow local safeguarding guidance.

A tracker should be presented as a shared safety tool, not a surveillance device. Agree in advance who may check the location, how often, and what they should do with the information. Put the agreement in writing if several family members are involved.

Families often revisit these decisions after a hospital stay, a change in medication, or a move. Write down what changed, who needs to know, and whether the current response plan still matches the person's needs. The alarm should support that review rather than replace it.

Battery life and coverage

A tracker is only useful while it has power and a signal. Check the realistic battery life with location updates enabled, not just the standby figure. Ask how long it takes to charge, whether the wearer can manage the charger, and what alert is sent when the battery is low.

Mobile coverage varies by network and by location. A tracker that works in a city centre may struggle in a rural area or inside a large building. Ask the provider which network the device uses and test it in the places the person visits.

Older adults are not a single group. Mobility, memory, dexterity, hearing, and confidence all affect whether a feature is helpful. Choose the simplest setup that covers the main risk, then add complexity only when there is a clear reason.

• Check the battery life with live tracking switched on.
• Confirm the network and coverage at home and on regular routes.
• Ask whether the device sends a low-battery alert.
• Check whether location history is available and who can see it.

Geofences and alerts

Many trackers can send an alert when the wearer leaves a defined area, sometimes called a geofence. This can be useful for a person who walks to a regular shop or day centre, but it can also create false alerts if the boundary is too tight or the location is inaccurate.

Set the boundary with the person and test it before relying on it. Decide who receives the alert, what they should do first, and when to call the police or a local missing-person service. A geofence is a prompt to check, not a guarantee that someone is safe.

For someone who values independence, the conversation should start with what they want to keep doing. A discreet format, a familiar responder, and a short daily check can feel more acceptable than a system that draws attention to frailty.

Questions to ask before buying

Ask whether the device is a tracker, an alarm, or both. Confirm the total monthly cost, the contract length, and what happens if the device is lost or damaged. Check the returns policy and whether the location data can be exported or deleted.

Ask how the provider handles a missing person situation. Do they contact emergency services, or does the family do that? What support do they offer if the tracker fails? A clear answer is more important than a long feature list.

• Does the device support two-way calling or only location tracking?
• Is the tracker waterproof and comfortable enough to wear every day?
• Who owns the location data, and how long is it retained?
• What happens if the wearer enters an area with no signal?
• Is there a plan for who searches and who calls emergency services?
