KEY FEATURES
Spheres
Create private location-sharing groups for your family, friends, or community. Only the people you invite can see what's inside.
Real-Time Location Sharing
Share your live location with the people who matter and feel their presence wherever you are. Stay connected, stay reassured.
Expiring Spheres
Plan event-based location sharing with built-in privacy. When the gathering ends, the sharing ends with it — automatically.

The app isn’t working. It worked good before they transferred to Sphere. “Contact us” resulted in an AI reply which solved nothing and indicated a lack of interest in fixing anything. It is and has been charged up, connected, and tells me it stopped working because there was a weak gps in the middle of a town of 169,000+ population. Do not get this. You will regret it and you will still be paying for the subscription.
Glitchy n they can’t fix it!
Kathiona
Their old app had fewer features but it did the main job of tracking n notifying in/out of Safe Zones very well. This newfangled one is not intuitive to use, requires several steps to get info rather than 1-2 clicks, and the Safe Zones do not work. Their support can’t fix it other than to tell me up widen the zone on the app well beyond the actual zone, still doesn’t work: no notificstions, wrong notifications, late notifications. Tack appears yo be trying to add some social aspect to their product n now the main reasons for it (tracking previous items/people/pets) has been compromised. I will be looking for alternatives as soon as my subscription expires.
App is very poor.

This app basically doesn’t work as stated. Safe zones don’t work and there are a lot of glitches to contend with. I thought such a small Cell-based tracker would be useful for being able to track my wife’s movements, who has Alzheimer’s. This device is not reliable in the 4 days I’ve had it. I’ll be looking for a replacement.
It was glitchy and unreliable for a bit but seems they fixed it - I’m comfortable relying for now

It’s so buggy and reliable to track 1/10 of the time. I don’t know why I still use this.
OurSphere 3.0.1 is yet another one of our biggest updates! Faster, smarter, and more alive than ever.
A MAP THAT COMES ALIVE
Watch your people move in real time. Moving avatars now glow with a cyan "sonar" ripple, pins pulse with a soft, satisfying bounce, and the map replays everyone's recent path the moment you open it. Press and hold anywhere for a snappy, tactile feel.
A SMARTER LOCATION HISTORY
See exactly where someone stopped and how long they stayed with new "time spent here" pills. Cleaner routes that trace real stops instead of messy scribbles, street-level zoom to see every detail, and quick day-to-day arrows to jump through time.
NEVER LOSE THEM AGAIN
We rebuilt background location tracking from the ground up. Far fewer gaps while driving, much more accurate "last seen" spots, and lightning-fast catch-up the moment your phone wakes — even when GPS is weak.
A FRESH, FASTER START
Say hello to a beautiful new branded splash screen and a warm "Welcome back" sign-in. The app now launches faster and smoother than ever.
SPHERES & DEVICES, PERFECTED
Sphere and device cards now match beautifully, showing live distance and "places today." The map follows whoever you're focused on as they move. Plus a redesigned "Add a Tack" flow with device categories, a refreshed profile editor, and a sleeker QR scanner.
SAFE ZONES & NOTIFICATIONS
Polished safe-zone editing with bigger handles and view-only guest mode, clearer notification icons, and more complete Traditional Chinese and Japanese translations.
…and dozens of smaller fixes to make everything feel just right.
Update now and see your world come to life.
