PAJ GPS Tracker for People with SOS Button
Real-time location, geofence alerts when someone leaves a safe area, and an SOS button. Small enough for a pocket, bag or keys. A service plan is required.
Wandering is one of the most frightening parts of caring for someone with dementia. The Alzheimer’s Association estimates that six in ten people living with dementia will wander at least once, and it can happen to someone who has never done it before. A person who leaves home confused, especially in bad weather or at night, can be in danger within hours.
A GPS tracker with geofence alerts won’t stop someone from leaving, but it changes what happens next. Instead of a frantic search, the caregiver gets an alert on their phone as soon as the person moves outside a safe area, and can see where they are on a map.
What Is a Geofence Alert?
A geofence is a virtual boundary you draw on a map in the tracker’s app, such as the home and yard, or a route to a familiar neighbor’s house. When the tracker moves outside that boundary, the app sends an alert to one or more family members’ phones. Most trackers let you set several zones and choose who gets notified.
For memory care, geofence alerts are usually more useful than live tracking alone. You don’t have to watch a map all day. You’re only notified when something changes.
What to Look For in a Dementia GPS Tracker
Will they actually keep it with them? This is the most important question, and the most common reason trackers fail. A device left on the kitchen table protects no one. Think about what the person always wears or carries: a watch, a particular jacket, a handbag, shoes, keys. Some families attach the tracker to the person’s keys or sew a pouch into a favorite coat.
Geofence alerts. Make sure the app supports geofencing with notifications to multiple caregivers.
Battery life and charging. A tracker is useless with a dead battery. Longer battery life and low-battery alerts to the caregiver’s phone matter more than extra features. Plan charging as part of a daily routine, such as overnight while the person sleeps.
An SOS button and two-way calling. Some trackers let the wearer press a button to call for help, or let a caregiver call the device and talk to the person. That’s helpful in early-stage dementia, while the person can still use it.
Subscription costs. Real-time GPS trackers need a cellular connection, so almost all of them require a monthly or annual service plan. Check the plan cost before buying the device, as it often matters more than the hardware price.
Coverage. Check which cellular network the device uses and whether coverage is good where the person lives.

The Picks in Detail
PAJ GPS Tracker with SOS Button — Best Overall
The PAJ person tracker combines real-time GPS, geofence alerts and an SOS button that sends an alert to caregivers when pressed. It’s small enough for a pocket, a bag or keys. The SOS button is most useful in earlier stages, when the person can still recognize they need help.
4G GPS Tracker with Two-Way Calling — Best for Staying in Touch
This 4G tracker works like a very simple phone: caregivers can see its location and call it, and the wearer can call preset contacts. Hearing a familiar voice can be reassuring for a person who feels lost, and it lets you guide them to stay where they are until help arrives.
PAJ 4G Tracker for Kids & Seniors — Best Compact Option
The PAJ 4G tracker is a small device designed to be attached to something the person always carries. It sends real-time location alerts to the caregiver’s app. It’s a good choice when the person won’t wear a watch or pendant but always takes their keys or handbag.
Dementia-Specific Options to Know About
Several services are designed specifically for dementia and are sold directly by their providers rather than on Amazon. Families often look at GPS SmartSole (a tracker hidden in a shoe insole, useful when someone won’t carry a device) and AngelSense (a wearable with caregiver monitoring features). Compare their subscription costs against the trackers above.
If the person uses an iPhone or an Apple Watch with cellular service, Apple’s Find My app can notify family when they leave a location, which works like a simple geofence with no extra subscription for location sharing. It requires the device to be charged, worn, and set to share location.
Free and Low-Cost Programs Worth Contacting
- MedicAlert with 24/7 Wandering Support, run with the Alzheimer’s Association: an ID bracelet with a 24/7 line that helps reunite a lost person with family.
- Project Lifesaver: many US sheriff’s offices and police departments run this radio-tracking bracelet program for people prone to wandering. Ask your local law enforcement agency whether it’s available.
- Your local Area Agency on Aging, which can point you to caregiver support and safety programs. Find yours at eldercare.acl.gov.
Tracking With Dignity
A tracker is a safety tool, but it is also monitoring a person’s movements. Where possible, introduce it early, while the person can understand it and agree. Frame it as staying connected rather than being watched. Avoid hidden “spy” trackers designed for vehicles or covert use, which are not built for this purpose. Talk with the person’s doctor and family about what level of monitoring is appropriate as the condition changes.
A Tracker Works Best as One Layer of Safety
Combine tracking with home measures that reduce wandering and falls: door chimes or alarms on exterior doors, a bed exit alarm for nighttime wandering, motion-sensor night lights, and a fall detection device. Our full guide to home safety for dementia and memory care covers each room of the house.
Frequently Asked Questions
What is the best GPS tracker for someone with dementia?
The best tracker is the one the person will reliably keep with them. Look for geofence alerts, good battery life, and a form they won’t leave behind, whether that’s a clip for their keys, a watch, or a shoe insole. For people in earlier stages, an SOS button or two-way calling adds reassurance.
Do GPS trackers for dementia need a monthly subscription?
Almost all real-time GPS trackers need a cellular service plan. Bluetooth tags like AirTags or Tile have no monthly fee, but they don’t send geofence alerts in the same way and work by being near other phones, so they are not a substitute for a real GPS tracker for someone at risk of wandering.
Can a fall detection device also track location?
Some mobile medical alert devices include GPS location so responders can find the person after a fall. See our fall detection guide. They focus on emergencies rather than geofence alerts, so some families use both.
What should I do if someone with dementia goes missing?
Search the immediate area briefly, then call 911 without delay. Don’t wait, because time matters. Tell them the person has dementia and share a recent photo. If they’re enrolled in MedicAlert or Project Lifesaver, contact those services too.
