GPS Trackers for Seniors: Choosing and Using Them Respectfully

How a GPS tracker works

A GPS tracker is a small device with a receiver that picks up signals from satellites to calculate its position, and a mobile connection (usually a SIM) to send that position to a server and then to an app on the family's phone. Some also use mobile tower and wifi information to estimate position, especially indoors where satellite signals are weak. Most trackers can:

• Show the current location on a map, updated every few seconds to every few minutes.
• Keep a history of where the person has been.
• Send geofence alerts when the person leaves or enters a chosen area, such as the home, the colony or the park.
• Offer an SOS button that sends an alert and location to chosen contacts.
• Allow two-way calls or voice messages.
• Show battery level.
• Detect falls or movement in some models; see fall detection watch guide.

Types of tracker

Wrist-worn trackers and simple watches. A watch-like device with a button, GPS and a SIM. Easy to wear, but must be left on the wrist; some people with dementia remove it. A strap that is hard to unfasten may be considered with care, and only with consent and the doctor's advice.

Pendant trackers. Worn on a lanyard. Convenient for people who dislike wrist devices, but can be left behind or removed.

Clip-on and pocket trackers. Small devices that can be put in a coat, bag, belt or pocket. Useful for someone who carries the same bag, but they may forget to take the bag.

Shoe or insole trackers. Hidden in the insole or shoe. Because the person is likely to wear shoes when going out, it is less likely to be left behind. These raise bigger privacy and consent questions, since the wearer may not know it is there; use only after discussion and, where appropriate, medical and ethical guidance.

Smartphones with location sharing. Many smartphones allow sharing location with family. This works only if the person carries and charges the phone, and understands it. Many older people leave phones at home or let them run out of charge.

Smartwatches. Offer GPS, calls and health features, but are more complex and need frequent charging; see GPS tracker or smartwatch.

Pet-style or asset trackers. Not designed for people; avoid.

Wearable alarms with a tracking option. Pendants that combine an alert button and location; see panic pendant buying guide.

What to look for

Reliable location. Ask about real-world accuracy, indoors and outdoors, and how often the position updates. In cities with tall buildings, accuracy may fall to tens of metres. Indoor accuracy is weaker.

Battery life. One of the main problems. Some trackers last a day or two, others several days or weeks, depending on update rate. A device that needs daily charging will be forgotten. Choose a battery life that matches your family's routine, and set a charging routine, such as every night at a charging dock; see safety device batteries and checks.

Network coverage and SIM. The tracker uses a mobile network. Check that your provider has good coverage where your parent goes. Ask whether the SIM is included or must be bought, whether a plan or recharge is needed and how fees work. We do not quote prices; compare plans in writing.

Geofencing. Allows setting a safe zone, with alerts when the person exits. Check whether you can set more than one zone and how quickly alerts arrive.

SOS and two-way communication. A button that the wearer can press, and a speaker and microphone for calling. Test the audio.

Size, weight and comfort. Light, with soft materials. Skin that is thin or sensitive needs a gentle strap.

Water resistance. For rain and hand washing, and for bathing if the maker says so.

Ease of use for the wearer and family. A simple app, clear map and straightforward settings. Large display and easy button. A device that requires complex steps will fail.

Tamper resistance and alerts. An alert if the device is removed or switched off can help, if appropriate and agreed.

Data and privacy practices. Who owns the data? Where is it stored? Can the maker see it? How long is it kept? Can you delete it? Does the app share data with third parties? Is there a secure login? Be cautious with unknown brands and apps with poor privacy policies; see spotting fake or poor quality care products.

Customer support and warranty. See equipment returns, warranty and servicing.

Consent, dignity and honesty

This is the heart of respectful use. A tracker follows a person's movements: where they go, when and for how long. That is private information, and an adult has a right to privacy, even when frail.

If your parent has capacity (can understand and decide):

• Ask them. Explain why you are worried, what the device does and who can see the information. Listen to concerns.
• Offer options and let them choose the style and when to use it. Perhaps they will carry it only on solo outings, or in the evenings.
• Be honest. Do not hide a tracker in their coat or shoes without telling them. Secret tracking can destroy trust if found, and may be unlawful or unethical.
• Agree on rules: who sees the location, when you will look (not constantly), and when it will be reviewed or switched off.
• Respect refusal. If they decline, look at other ways to meet your worry, such as a regular phone call, an agreed route, a friend or neighbour, or a device they accept, such as a panic pendant.
• Do not use it to control their freedom or to check on private visits.

If your parent lacks capacity (for example, advanced dementia):

• Decisions should be made in their best interests, with the least restrictive approach, involving the doctor, the family and, where possible, the person themselves.
• Explain in simple words and gain assent where possible, even if they cannot give formal consent.
• Use the tracker for safety, not for convenience or surveillance, and review whether it is still needed.
• Limit who has access and how data is used.
• Discuss with the doctor or a dementia specialist.
• Avoid deceptive methods where possible.

Using a tracker well

1. Choose with your parent, and test a few styles. 2. Set up the app on the phones of at least two family members, so alerts are not missed. 3. Set geofences around the home and regular places, and test them. 4. Set emergency contacts, and decide who responds; see responding to an alert: who does what. 5. Teach the wearer to press SOS, and practise. 6. Establish a charging routine, and keep a spare charger. 7. Check the device daily, and note low battery alerts. 8. Wear it consistently, ideally attached to something they always take, such as a watch or a belt. 9. Do not rely on it alone. Also use ID, neighbours and a plan; see wandering and dementia safety. 10. Review regularly: is the device still needed, comfortable and accepted? 11. Do not monitor constantly. Check when there is a reason, not as a habit. 12. Respond respectfully to alerts: call first, then go.

Limits of GPS trackers

• They need to be worn and charged.
• Indoor and urban accuracy is limited.
• Mobile coverage gaps leave blind spots.
• Delays: location updates may lag; an alert may arrive late.
• False alerts from geofence drift.
• They do not stop someone leaving, or get lost.
• They do not provide medical help.
• They do not promise a rescue. Someone has to see the alert, decide and act.

For indoor wandering at night, door sensors and bed sensors may be more helpful; see door sensor guide.

Alternatives and complements

• ID bracelet and wallet card with name and phone number.
• A tag in clothing.
• Neighbours, shop keepers and security staff who know the person.
• A regular routine and company on walks.
• A mobile phone with simple settings, if the person can use it; see phone accessibility features for seniors.
• A panic pendant or watch; see panic pendant buying guide.
• A community plan, such as a resident welfare association watch.

When to ask a professional

Ask a doctor or memory specialist about wandering, safety and the ethics of tracking for a person with dementia. An occupational therapist can advise on devices and home safety. A lawyer may advise on consent and decision-making for a person lacking capacity; see legal basics: wills and power of attorney. Dementia organisations and Elderline 14567 can offer guidance on services. If a person is missing or in danger, call 112.
