Cosmo Watch Review: The JrTrack 4 Smartwatch For Kids

Alessandra | Posted on July 28, 2025 |

I recently got a JrTrack4 Smartwatch for my son. Here is my honest Cosmo Watch review and why I think it’s totally worth it!

If you’re a parent who’s not quite ready to hand your child a smartphone then you’re in the right place! As a mom of 3 and my oldest just turning 10 years old, I’m very against smartphones and children. I even signed the Wait ‘Til 8th Petition, which is a community of families waiting until at least after 8th grade to give their kids smartphones. But, while holding off on smartphones is great, you still need to stay connected with your preteen. At this age they might be staying home alone for short periods of time, going to their friend’s homes, and they are just inching into that first big step towards independence. Well, that’s where the Cosmo JrTrack 4 Smartwatch comes in and might be exactly what you’re looking for! In this blog, I’m sharing my personal Cosmo watch review, and I’ll walk you through everything you need to know: how it works, how easy it is to use, who it’s best for, its standout features, setup instructions, and whether it’s worth the price.

Cosmo Watch Review

So, now that you’ve gotten this far, I’m guessing we’re in the same boat. You know, the holding off on smartphones and social media for kids boat. I opted for this smartwatch for my 10 year old son because I needed him to have a way of getting a hold of me or my husband, safely, if and when he’s away from us, like going to a friend’s house. People don’t have landlines like they use to, and it feels more personal to ask someone to borrow their cell phones these days. So, this watch just made sense for us right now. Keep reading to learn more about it!

What Is the Cosmo JrTrack 4 Smartwatch?

First off, you might be wondering what even is the Cosmo JrTrack 4 watch. And it’s a great question! Simply put, it’s a kid-friendly smart watch with GPS tracking, call/text capability, and safety features, designed for younger children who aren’t quite ready for the responsibility of a full-blown smartphone. And if you ask me, no child is ready for a smartphone, so keep reading for more information about this awesome watch.

Is It Easy to Use?

For the most part, this watch is very easy to use. The interface is simple and straightforward. Kids can make calls, texts, send voice messages, and check the time with just a few taps. Plus, the parent-friendly COSMO Mission Control app allows you to control all settings remotely from your own phone, making management a breeze. You can keep track of everything in the app. Even if you’re not super tech-savvy, the setup and daily use are simple. The hardest thing about it is texting because the screen is small, so my son usually opts to send a voice recording via text instead.

Who Is It Perfect For?

The JrTrack4 watch says it’s meant for children ages 5-12. In my opinion, 5 is too young and a watch like this is not needed for a child under 9 or 10, but that’s just me. I believe this watch is ideal for 10-15 year olds and ideal for parents who are holding off on giving their child a cell phone but still want a reliable way to communicate and keep tabs on them.

It’s perfect for children who are stepping into that independent stage. Children who are being dropped off at sports, friend’s houses, or staying home alone for short periods of time will benefit from this watch. I love that this watch allows to parents to only give children access to approved contacts, meaning they are not interacting with peers just yet. My son’s watch is set to only be allowed to call me and my husband.

How Much Does The Cosmo JrTrack 4 Smartwatch Cost?

The watch retails at $129.99 but there are often deals and coupons for it. You can also get cashback for it with Rakuten. It also requires a monthly cellular plan, which starts at $17.99/month through Cosmo’s service. There are also other options available, like paying up front for 6 to 12 months at a time instead of paying monthly. I opted for the monthly plan. You get unlimited talk, text, and data with each plan so you can pick whatever works for your family! Each plan is also backed by a 30 day money back guarantee.

Features Breakdown

Now that you know the who, what, and whens about the Cosmo Watch, here is a breakdown of soem of the best features of the JrTrack 4:

📍 Real-Time GPS Tracking – Know exactly where your child is at any time
📞 Calling + Voice Messaging – Two-way communication with only approved contacts (my favorite part!)
🧱 Safe Contact List – No spam, strangers, or outside access (you get to choose who contacts your child and vice versa)
🔒 Geo-Fencing – Get alerts when your child leaves or enters a safe zone
📵 School Mode – Blocks distractions during class time

How Long Does the Battery Last?

This watch offers so much right? So now, you know your child can make phone calls, texts, and listen to music, how long does that battery actually last?Well first, using apps/games will drain the battery quicker. But the battery will last about 36-48 hours with normal use, which I think is pretty impressive for a kid’s smartwatch with GPS and cellular capabilities. My son has gotten into the habit to just charge it each night so it will stay charged through the next day though. It takes a few hours to charge, but you can rest assured that your child can wear it all day without worrying about power. Plus, the Mission Control App will let you know when the power is getting low and needs to charge!

How to Set Up Your Cosmo Smartwatch

So you’ve decided to make the purchase for this awesome kid’s smartwatch? Luckily, setting up the Cosmo JrTrack 4 is simple! Below is a list of how to set up your new watch.

Download the COSMO Mission Control app and create an account (available on iOS and Android)
Activate your cellular plan through Cosmo directly
Scan the QR code on the watch using the app

The app will walk you through every step, and like I said early, it’s super simple. But if you run into an issue, there’s also video support and a helpful FAQ section on Cosmo’s website if you need it!

Cosmo Watch Review: Is the Cosmo JrTrack 4 Worth It?

Simply put YES, this watch is worth it. If you’re a parent looking for peace of mind and a way to stay connected with your growing child without opening the can of worms that is smartphone life and social media, yes, it’s 1000% worth it! The Cosmo JrTrack 4 strikes the perfect balance between safety, simplicity, and freedom (which is so exciting for big kids!) It’s affordable, reliable, and built with families in mind. I love their motto too: “1990 Simple. 2025 Smart.”

The experts say that when you give a child a smartphone, you’re taking away their childhood. That hits hard (for me anyway!) The Cosmo smartwatch gives parents peace of mind because we live in a world of technology, but we don’t have to steal our children’s childhood either. We, as parents, can work with technology and Cosmo helps! I truly believe it’s one of the best smartwatches for kids on the market right now.
