Detailed Reviews
COSMO JrTrack 5 Kids Smart Watch
Best for: Best for Parental Controls
Ages: Ages 6+
This is the most feature-rich option on the list, and also the only one that requires an ongoing cellular plan. The JrTrack 5 includes built-in GPS with SafeZone alerts, so parents can define geographic boundaries and receive a notification when a child leaves them. Calling and texting work only through parent-approved contacts, which addresses a real concern many families have about handing a connected device to an elementary schooler. A school lock mode can disable the watch during class hours, and an SOS button gives kids a direct emergency line. Spotify Kids access is listed as a feature, but it requires a separate compatible subscription. A SIM card is included in the box, though a COSMO Mobile monthly plan is still required for the device to function. If you want GPS and communication gated by parental approval, this is the pick. If you do not want a recurring cellular bill, skip it.
Buy this if: Your child is 6 or older and you want location monitoring, real calling, and the ability to approve every contact.
Skip this if: Your child is under 6, or you want to avoid an ongoing cellular subscription.
BIGGERFIVE Smart Watch for Kids Brave 2
Best for: Best Budget Option
Ages: Ages 5+
The Brave 2 is the practical middle-ground pick for families who want a capable fitness tracker for kids without signing up for anything monthly. It works in standalone mode right out of the box—no phone pairing required for basic functions like step counting, time, and games. The 1.8-inch HD touchscreen is notably large for this price tier, and the seller lists 80-plus sport modes alongside real-time heart rate monitoring and sleep tracking. IP68 waterproofing means poolside or rain use is less of a worry. Five parent-controlled puzzle games add some fun without handing kids an open app store. The important tradeoff: there is no GPS and no calling capability, so this watch cannot help you locate your child or let them reach you in an emergency. Health readings, including heart rate, should be treated as general activity indicators rather than medical measurements.
Buy this if: You want activity tracking and games with zero subscription cost and no cellular plan.
Skip this if: GPS location, SOS calling, or two-way messaging are priorities.
Fikami Smart Watch for Kids
Best for: Families considering this exact model or bundle
Ages: Ages 6+
Where the Brave 2 is fully standalone, this Fikami model is built around Bluetooth connectivity to a parent’s or older child’s phone. When paired, it can mirror incoming call alerts, SMS messages, and WhatsApp notifications directly to the wrist—a step up for kids who are old enough to benefit from that awareness but not yet on their own phone plan. The 1.83-inch touchscreen, IP68 waterproofing, heart rate monitoring, sleep tracking, step counter, and 12 built-in puzzle games are all present here, along with 60-plus watch faces and a DIY option that lets you upload your child’s photo. Notably, this watch does not support a SIM card and cannot place or receive actual calls on its own. The notification feature depends on maintaining a Bluetooth connection to a paired phone. No subscription is required.
Buy this if: You want your child to see incoming phone alerts on their wrist without a cellular plan or SIM card.
Skip this if: You need the watch to make calls or work independently without a nearby paired phone.
BIGGERFIVE Vigor 3 Kids Fitness Tracker Watch
Best for: Families considering this exact model or bundle
Ages: Ages 5+
The Vigor 3 separates itself from most kids’ fitness bands with an AMOLED screen—the same display technology used in many adult smartwatches. Colors tend to look richer and more vivid than on standard LCD panels, which can make it genuinely more engaging for kids who care about how their watch looks. The seller also states a 10-day battery life, which would mean less frequent charging than most comparable devices. Core tracking features include heart rate monitoring, sleep tracking with a daily sleep score, a pedometer, and 10 sport modes. The 3ATM water resistance rating covers splashing and brief submersion, though it is worth checking the listing for specific guidance on swimming. No app, subscription, or cellular service is required. As a tradeoff, the Vigor 3 has fewer sport modes than the Brave 2 and no notification mirroring.
Buy this if: Display quality and battery longevity matter to your family and you want a no-subscription fitness tracker.
Skip this if: You need GPS, calling, or a larger library of sport modes.
Fikami Kids Sport Watch with Fitness Tracker
Best for: Families considering this exact model or bundle
Ages: Ages 6+
This second Fikami option targets families who want a solid core feature set at the lowest entry point on this list. The 1.83-inch touchscreen, IP68 waterproofing, heart rate monitoring, sleep tracking, step counter, and 12 puzzle games line up closely with the other Fikami model above. Bluetooth notifications are also present, so it can mirror phone alerts when paired. No subscription is required, and basic use does not require a phone at all. The main consideration here is that this watch and the Fikami Smart Watch for Kids share many of the same listed features—so if the notification or game features are the priority, review both listings carefully before deciding. Neither does GPS or independent calling.
Buy this if: You want the Fikami feature set at the most accessible price point and do not need GPS or cellular capability.
Skip this if: Location tracking, SOS calling, or a premium display are important to your family.
How to Choose
The single most important question to ask before buying a fitness tracker for kids is: do I need to be able to reach my child, or locate them, through the device itself? If yes, only the COSMO JrTrack 5 on this list does that—and it requires a monthly cellular plan. Every other option here relies on Bluetooth or works fully offline. That is not a flaw; it is a category difference.
- For safety and communication: COSMO JrTrack 5 is the only pick with GPS and real calling.
- For subscription-free activity tracking: BIGGERFIVE Brave 2 or Vigor 3 are both solid choices; the Vigor 3 has the better display, the Brave 2 has more sport modes.
- For notification mirroring from a phone: Either Fikami model works, since both support Bluetooth alerts.
- For the lowest upfront cost: The Fikami Kids Sport Watch is the most accessible entry point.
Also consider waterproofing ratings. IP68 generally covers submersion beyond a meter; 3ATM covers splashing and rain. Check the specific listing for guidance on swimming before letting any watch near a pool.
Frequently Asked Questions
Do kids’ fitness trackers require a phone to work?
Three of the five picks here—BIGGERFIVE Brave 2, BIGGERFIVE Vigor 3, and Fikami Kids Sport Watch—work in standalone mode for basic features. The two Fikami models also support optional Bluetooth pairing for notifications. Only the COSMO JrTrack 5 requires a cellular service subscription.
Are the health readings on these watches medically accurate?
No. Heart rate, sleep, and calorie readings on consumer kids’ wearables should be treated as general activity indicators, not clinical measurements.
Do any of these have GPS?
Only the COSMO JrTrack 5 includes GPS tracking. All other models on this list do not offer location tracking.
What is the youngest recommended age for these devices?
Based on the product listings, the COSMO JrTrack 5 is noted for ages 6 and up. The two Fikami models list ages 6 and up. The BIGGERFIVE Brave 2 lists ages 5 and up, and the Vigor 3 also lists ages 5 and up. Always check the current listing for the most up-to-date age guidance.
Final Recommendations
If parental oversight and two-way communication are your top priorities, the COSMO JrTrack 5 is the standout choice—just go in knowing the monthly plan is non-negotiable. For families who want a capable fitness tracker for kids without any recurring cost, the BIGGERFIVE Brave 2 offers the broadest sport-mode library, while the Vigor 3 wins on display quality and seller-stated battery life. Either Fikami model works well for budget-focused buyers who also want Bluetooth notification support. No single watch is perfect for every child, but matching the device to your actual priorities—communication, activity, or cost—will get you much closer to a purchase you will not regret.
