Chocolate -  It's all about love

It's so much more than a kids smart watch.

What makes COSMO different? Everything.

When we set out to build the best smartwatch for kids, we knew it wouldn't be easy. Kids need more than cheap toys or adult devices patched over with parental controls. And parents shouldn't have to choose between safety & connection.

So we started from the ground up. We tried all the kids wearables out there. We talked to parents, teachers, tech & security experts, and most importantly, kids! And then we started building, with every aspect engineered for security, safety, and simple connection.

Because this is so much more than a kids smart watch. It's a safer, smarter start. It's peace of mind for parents. And it's all to help bring families like yours closer together.

  • Most Safety

    The only kids smartwatch with SOS Alerts, Geofencing, and 911 calling capabilities.

  • Most Savings

Membership FAQ's

Does each watch need it's own membership plan?

Yes, each COSMO JrTrack watch requires its own separate COSMO Membership plan.

When do I purchase a membership?

If you're buying a Renewed JrTrack, you will purchase your Membership plan at the same time as your watch. When your watch arrives, simply pair it with the parent app and you're good to go!

Can I add JrTrack to my existing phone plan/provider?

JrTrack is a stand-alone phone with it’s own pre-installed SIM card that operates only on COSMO's Family-Safe Nationwide Network plans. JrTrack can't be added to an existing service plan with a different provider like Verizon or AT&T.

How do I know if I have coverage in my area?

COSMO’s Membership service operates off of T-Mobile cellular towers. Be sure to check T-Mobile’s coverage maps for service in your area. COSMO currently only offers service to customers in the US, though we hope to expand soon!
