GPS Trackers for People With Dementia: A Practical Guide for Families

There's a particular kind of fear that comes with caring for someone who might walk out the front door and not find their way back. It sits in the background of every day, spiking when the house goes quiet or when your phone rings unexpectedly.

GPS tracking doesn't eliminate that fear entirely. But it can reduce it from a constant roar to a manageable hum — and that makes a genuine difference to how you live.

This guide walks through the different GPS options available, what actually works in practice, and how to choose the right approach for your family. We'll be honest about the limitations too, because no technology is a complete solution.

Why location becomes a concern

People living with dementia may leave their home for a variety of reasons — a habitual walk, searching for something familiar, responding to a past routine (like going to work), or simply feeling restless. The term "wandering" is commonly used, though many families and professionals prefer more respectful language like "walking with purpose" — because from the person's perspective, there usually is a reason.

Whatever you call it, the safety concern is real. Someone who leaves home may become disoriented, unable to find their way back, and potentially vulnerable to weather, traffic, or other risks.

The statistics are sobering: a significant proportion of people living with dementia will leave their home unaccompanied at some point, and the risk of harm increases sharply the longer someone is lost.

GPS tracking is one piece of the safety puzzle — alongside environmental adaptations, routine management, and community awareness.

The three types of GPS solutions

1. Dedicated GPS devices

These are purpose-built trackers — small devices designed specifically for location monitoring.

Examples: Jiobit, AngelSense, GPS SmartSole (insole), Theora Connect, various pendant-style trackers.

How they work: The device carries a SIM card and GPS chip. It periodically sends its location to a server, which you access via an app on your phone. Most support geofencing (alerts when leaving a defined area), location history, and some offer two-way communication.

Advantages:

• Don't require the person to carry a smartphone
• Often smaller and more discreet than a phone
• Some can be worn as a watch, clip-on, or even built into a shoe insole
• Purpose-built battery management (some last days between charges)
• Work even if the person doesn't know what the device is

Disadvantages:

• Monthly subscription costs (typically for the SIM/data)
• Another device to remember to charge
• Can be removed, lost, or forgotten
• GPS accuracy varies (especially indoors)
• Limited functionality beyond location

2. Phone-based tracking

Using the person's existing smartphone (or a simple smartphone set up for them) to share their location.

How it works: An app on their phone shares location data with family members. This can be a general location-sharing app (like Google Maps location sharing, Apple Find My) or a purpose-built care app that includes location alongside other features.

Advantages:

• No extra device — uses what they already carry
• Often free or included in a broader care app
• Can combine location with other features (emergency contacts, navigation home, daily plan)
• GPS on modern phones is highly accurate

Disadvantages:

• Relies on the person carrying their phone (and keeping it charged)
• Smartphone battery life with active GPS can be poor
• Requires initial setup and permissions
• Phone can be lost, left at home, or turned off
• May feel more intrusive than a discreet tracker

OurTurn's approach: The patient app includes safe zone monitoring — you set up areas (like home, a family member's house, the local park) and receive alerts if your loved one leaves them. There's also a "Take Me Home" button that opens map directions with a single tap, so if they're out and feeling unsure, they can navigate back without needing to type an address or figure out a map app.

3. Smart home and environmental sensors

Not GPS in the traditional sense, but these complement location tracking by monitoring movement within the home.

Examples: Door/window sensors, motion detectors, smart doorbells with cameras, bed sensors.

How they work: Sensors detect when a door opens, when there's movement (or lack of it) in a room, or when someone approaches the front door. Alerts are sent to your phone.

Advantages:

• No wearable required
• Very reliable within the home
• Can also detect falls, inactivity, or unusual patterns
• Some integrate with smart home systems you may already have

Disadvantages:

• Only work within the home (no outdoor tracking)
• Can generate frequent false alarms
• Installation can be complex
• Multiple sensors across the home gets expensive

The best approach for many families is a combination: environmental sensors at home (especially a door sensor) plus a GPS solution for when they're out.

What to look for when choosing

Not all GPS solutions are equal. Here's what matters in practice:

Accuracy

GPS is accurate to within a few metres outdoors, but struggles indoors and in dense urban areas. Some devices supplement GPS with Wi-Fi positioning and mobile network triangulation, which helps. Ask: how accurate is the device in the places your loved one actually goes?

Battery life

This is the silent killer of GPS tracking. The most accurate, most feature-rich device in the world is useless if the battery dies by lunchtime. Look for:

• Battery life measured in days, not hours
• Intelligent tracking (updates more frequently when moving, less when stationary)
• Easy charging (a dock or magnetic charger is better than a fiddly cable)
• Low-battery alerts sent to your phone

Geofencing and alerts

Geofencing means drawing a virtual boundary on a map and getting an alert when the device crosses it. This is arguably the most useful feature — you don't need to stare at a map all day; you just need to know when something unexpected happens.

Look for:

• Multiple geofences (home, a relative's house, a regular walking route)
• Customisable alert methods (push notification, text, phone call)
• Speed of alerts (some devices check in every few minutes; others are near-real-time)

Ease of use (for you and for them)

For the person with dementia: the device should require zero interaction. They shouldn't need to press buttons, charge it themselves, or understand what it does. The less they need to think about it, the better.

For you: the companion app should be straightforward. You need to see where they are, get alerts, and check history — without navigating a complex interface.

Privacy and dignity

This is the aspect most product reviews skip, and it might be the most important one.

GPS tracking involves monitoring another person's movements. For someone in early stages who is aware of their condition, this can feel controlling, infantilising, or deeply uncomfortable — even when they understand the safety reasons.

How to approach it with respect:

• Involve them in the decision whenever possible. "We'd both worry less if we knew you could always find your way home. What do you think about this?"
• Frame it as mutual — location sharing can go both ways. "You can see where I am too."
• Focus on the positive — independence and freedom, not surveillance. "This means you can keep going on your walks."
• Revisit the conversation as things change. Consent given in early stages may need to evolve as the condition progresses.

Setting up safe zones that actually work

A safe zone that's too small will generate constant false alarms. A safe zone that's too large won't catch genuine concerns. Here's how to get it right:

Start with daily patterns. Before setting up geofences, observe where your loved one actually goes over a typical week. Their regular walk, the corner shop, a neighbour's house, the bus stop. Your safe zone should encompass their normal movements.

Build in a buffer. If their usual walk takes them 500 metres from home, set the safe zone at 750 metres. You want to catch unexpected departures, not every trip to the letterbox.

Use multiple zones. Most solutions support several geofences. Set one for home, one for a family member's house they visit regularly, one for a day centre if they attend one. This way, you're alerted when they're somewhere truly unexpected — not just somewhere other than home.

Adjust over time. As your loved one's habits and abilities change, your safe zones should too. Review them every month or two.

When someone does leave the safe zone

Having a plan matters more than having technology. If you receive an alert:

1. Don't panic. Check the location on the map first. They may be at a familiar place just outside the boundary.
2. Call them if they carry a phone. Keep your voice calm and orienting: "Hi Mum, it's Sarah. Are you okay? Where are you?"
3. Go to them if they seem confused or can't tell you where they are. Or send the nearest family member.
4. If you can't locate them: contact the police non-emergency line promptly. Don't wait hours hoping they'll come back. Early reporting leads to faster, safer outcomes.
5. After the event: review what happened. Can you adjust the safe zone? Is there a time pattern? Is the front door sensor working? Use each incident to improve the system.

The honest limitations of GPS tracking

No technology is a complete answer:

• GPS doesn't prevent someone from leaving. It tells you where they are after they've gone. Prevention requires a different set of strategies — routine, environmental cues, engagement, and addressing the underlying reasons for restlessness.
• Devices can fail. Batteries die, signals drop, devices get left behind. GPS should be one layer of your approach, not the only one.
• Alerts require someone to respond. A geofence alert at 2am is only useful if someone is awake to see it and able to respond.
• It can create false security. "They have a tracker, so they're safe" is a dangerous assumption. They have a tracker, so you can find them faster — but the risk of something happening in the meantime remains.

GPS tracking is a tool, not a solution. It's most effective when combined with a thoughtful daily routine, an adapted home environment, community awareness, and multiple people sharing the responsibility of care.
