What caregivers say
From families who use it.
I bought a tack so I can keep an eye on my Mom who lives in a different city than me. I love the geofence! It sends me an alert when she leaves her building … The tack has eased my mind.
We got this device because my 89 year old dad got lost a couple of times from his assisted living home… Could not have found him without this device.
I bought this for my mother in law who has later stages of dementia… So I wanted something that we could see where she's at without taking her independence away.
Using this product to help me track a family member with dementia. Particularly liked the ability to set up a safety zone and get notified as soon as she leaves that area it has reduced my stress immensely.
Great little tracker,bought 4 to track my mother that has dementia, app interface is nice, does all you need.
My wife has dementia and she is libel to walk out of the house at any time. If this happens, I have the satisfaction of knowing that I can find her quickly. … the app is easy to use. A great device that helps to keep her safe.
The device works great! I’m very pleased. It tracks my father both indoors and out and it really makes me worry less about him. … Also, the price of the device and the subscription is very affordable and worth it compared to the spotty coverage of Bluetooth only devices.
I'm using it to track my husband who has Alzheimer's. It really helps when he's out walking. I know he is not going to get lost. I have it attached to his keys, and he always has his keys with him (I make sure of that). So far, so good!!
We bought this for my Mum who has dementia. It is an amazing product and provides incredibly accurate location information. Very highly recommended
My husband suffered a mini-stroke in September. He was used to walking 3-miles a day by different routes. We were worried about something happening while he was out. … I can track him no matter where he is.
We are on a fixed income; sadly my husband has Parkinson's disease with dementia and he gets lost easily. I ask him not to leave but he does when I am not looking. This wonderful device helps me find him. Great little tracker.
I bought 2 of these for my parents as they travel to AZ from MN. They both use flip phones … I get notices when it needs to be recharged as well as when they are "on the move". Great ease of mind!!!

Common questions
What caregivers ask us first.
The questions our support team hears most from families caring for an older relative.
Can a GPS tracker help someone living with dementia?
Yes, it is one of the tools caregivers use. Tack GPS reports its own location, so if a walk goes further than planned you can see where they are, and safe zones tell you when they leave a familiar area.
Does the person wearing it need a phone?
No. The SIM is built into the tracker, so the person wearing it needs no phone, no app and no screen to learn. They press one button to send an alert. You follow their location in the OurSphere app on your own phone, and safe zone alerts arrive there too.
Can I just use an AirTag instead?
An AirTag has no connection of its own. It only shows up when someone else's iPhone passes nearby, keeps no history and sends no zone alerts. Tack GPS has its own SIM, so it reports from anywhere it has coverage, keeps location history and tells you when they leave a safe zone.
How does Fall Detection work?
On Tack GPS Plus, motion sensors spot a hard fall and send an alert to OurSphere with no button press. Switch it on in the app. It works when worn by the older person, can miss a fall or trigger by mistake, and is not a medical device.
Will it work inside a mall or an apartment block?
Yes. Indoors it uses Wi-Fi positioning, typically accurate to 10 to 30 metres, then nearby cell towers. On Tack GPS Plus, Indoor Elevation Finder shows how many metres above or below you it is, so you know which way to go.
Can more than one family member see the location?
Yes. Everyone in your Sphere sees the same map and gets the same safe zone, One-Click and fall alerts at the same moment. You can also give ongoing access with a Guest Access Code, or send a link that works for 1, 3 or 7 days to someone without the app.
Can I see where they walked earlier in the day?
Yes. OurSphere saves every location the tracker reports, so you can pick a day and replay the route on the map. It goes back 14 days on the Standard Tack Cloud plan and 90 days on Premium. It helps when you need to know where a walk went, or where a search should start.
Can it be worn out of sight?
Yes, and securely. The Wonder Pin Pouch, included in the Tack GPS Plus Care Bundle, pins the tracker inside clothing, and the pin only opens with the Magnetic Key you keep. Out of sight and locked on, it is hard for the wearer to take off or leave behind. The bundle also has a breakaway lanyard for wearing it around the neck.
Does it work abroad?
Yes, in supported countries. Tack GPS works in 30+ countries and Tack GPS Plus in 120+, with roaming included in your Tack Cloud plan. Neither model covers Vietnam, mainland China, Hong Kong or Macau, so check the coverage list for every country on the trip before you travel.
What does it cost?
Tracker prices are shown above. Each tracker also needs a Tack Cloud plan, from $5.42 SGD a month on a one-year Standard plan or as low as $3.89 SGD on a three-year plan, with 30 days included. Two-year plans are on our site too, and a 3-month plan is in the OurSphere app.
Is there a discount for CARA members?
Yes. CARA members get 20% off Tack GPS Plus, the Care Bundle and accessories, using the code in the CARA app. CARA is Dementia Singapore's programme for people living with dementia and their caregivers. The standard Tack GPS is not included in the offer.
How often does it need charging?
Up to 30 days per charge in Standard Mode. Charging takes about 1.5 hours over USB-C, and the tracker keeps working while it charges. Emergency Mode updates more often, so it uses more battery. OurSphere shows the battery level, so you can recharge on a routine before it runs low.
