A note on safety features: GPS watches, SOS buttons, and location alerts are helpful tools, but no device replaces adult supervision or a family safety plan. Follow the manufacturer’s setup guidance for emergency features and test them together with your child.

Every one of these watches hides most of its real price in the monthly plan, so the sticker tells you almost nothing — which is why picking the best kids smartwatch starts with two years of math, not a shelf comparison. Run that math and the answer is clearer than the marketing suggests: the Bark Watch is the most complete package for kids 9 and up, the Verizon Gizmo Watch 3 Adventure is the cheapest to own by a wide margin, and the COSMO JrTrack 5 is the pick for younger kids who want a camera. The Gabb Watch 3e remains the minimalist favorite, with one caveat parents should know before buying.

Our picks at a glance

  • Best overall (ages 9–14): Bark Watch — unlimited contacts, a real camera, 911 capability, and the longest battery life in independent testing.
  • Best budget: Verizon Gizmo Watch 3 Adventure — roughly $379 all-in over two years, at least $50 less than anything else here.
  • Best for younger kids (5–12): COSMO JrTrack 5 — camera, music, and talk-to-text on the entry plan, with room to grow.
  • Best distraction-free: Gabb Watch 3e — the least screen-time temptation of the four, if you can accept its missing emergency-dial option.

How do the four watches stack up?

The short version: all four track location and let your kid call and text approved contacts. The differences live in contact limits, cameras, emergency calling, and — biggest of all — what the plan costs after the box is opened. Figures below reflect SafeWise’s January 2026 kids-smartwatch testing and published pricing at that time; plans and street prices shift, so treat the gaps between models as the durable signal.

The two-year math: what each watch really costs

This is the table we built because nobody selling these watches will. A kids smartwatch is a subscription with a screen attached: over a typical two-year run, the plan costs two to three times the hardware. We totaled device, activation, and 24 months of service using the pricing SafeWise reported in its January 2026 testing, taking each plan’s published range where one exists.

WatchDevice + fees24 months of serviceTwo-year totalEffective monthly cost
Gizmo Watch 3 Adventure$139 ($99 + $40 activation)$240$379~$15.80
COSMO JrTrack 5 (base plan)$164.99$263.76$428.75~$17.85
Gabb Watch 3e (base plan)$149.99$311.76$461.75~$19.25
Bark Watch$168 (financed $7 × 24)$360$528$22.00
Gabb Watch 3e (top plan)$149.99$431.76$581.75~$24.25
COSMO JrTrack 5 (top plan)$164.99$599.76$764.75~$31.85

Two things jump out. First, the Bark Watch’s “$0 upfront” is financing, not a discount — you pay $168 for the hardware either way, just spread out. Second, the COSMO is both the second-cheapest and the most expensive watch in this comparison depending on which plan tier you pick, so decide which features you need before checkout, not after. The Gizmo’s win here is structural: Verizon’s $10 line price undercuts every dedicated kids-watch plan.

The battery honesty gap

Advertised battery numbers on kids watches are strange in both directions, so we computed the gap between the box and the bench. In SafeWise’s testing, the Bark Watch nearly doubled its own claim while the Gizmo delivered half of its headline figure — and both landed on the same real-world number.

Gabb Watch 3e24 hours34 hours142%
COSMO JrTrack 524 hours29 hours121%
Gizmo Watch 3 Adventure86 hours43 hours50%

The practical takeaway: every watch here survives a school day with margin, and the Bark and Gizmo will usually survive two. Charge nightly anyway — the failure mode that matters isn’t day two, it’s a dead watch at 3 p.m. pickup.

Bark Watch: the most watch, for the oldest kids

The Bark Watch is the one that behaves most like a phone alternative rather than a tracker with buttons. Unlimited contacts, voice and text messaging, photo texting from a 5MP camera, 911 capability, school mode, and remote shutdown cover essentially every job a parent hires one of these for. It also posted the best tested battery life of the group at 43 hours.

Built for ages 9 to 14, the Bark Watch behaves more like a phone alternative than a simple tracker.

The trade-offs: it’s aimed at ages 9–14 and it feels that way — there are no games at all, which is a feature for parents and a bug for eight-year-olds. There’s no video calling, and at $22 a month all-in it’s the second-priciest path in our two-year table. Dealbreaker check: if your child is under 9, look at the COSMO or Gizmo first.

Gizmo Watch 3 Adventure: the budget answer, with a catch

If you’re already a Verizon household, the Gizmo is the value play and it isn’t close — $379 over two years, a durable Adventure casing, educational games, school mode, and an audio drop-in feature that lets a parent listen in when a call goes unanswered. Talk-to-text and a 20-contact list handle the communication basics.

The trade-offs: 20 contacts is the tightest list here, there’s no camera on the Adventure model, and the 86-hour battery claim is marketing — plan on the same 43 real hours the Bark delivers. The bigger catch is the carrier lock: this is a Verizon product, so families on other carriers should price in a line with Verizon or move on.

COSMO JrTrack 5: the sweet spot for the 5–12 crowd

The JrTrack 5 covers the widest useful age range of the four. Younger kids get a simple call-and-track device with an SOS button and 911 capability; older kids grow into the 2MP camera, music streaming, talk-to-text, and optional learning apps. A 100-contact list gives families room that the Gizmo can’t match.

The trade-offs: plan tiers span $10.99 to $24.99 a month, and the top tier makes this the most expensive watch in our comparison — pick the base plan unless you know why you’re upgrading. There’s a $15 activation fee, no video calling, and its 29-hour tested battery, while fine, trails the group.

Gabb Watch 3e: minimalist by design, with one real gap

Gabb’s whole pitch is less: no camera, no internet, no app store, and a virtual pet that rewards steps as the lone entertainment. For families whose goal is a device the child forgets about between calls, that restraint is the product, and school mode plus safe zones round out the parental controls.

The trade-offs are real, though. Per SafeWise’s testing notes, the Gabb Watch 3e has no 911 dialing option — its SOS button alerts approved contacts instead — and it doesn’t keep location history. It also isn’t the budget pick its simplicity implies: at $461 to $581 over two years, it costs more than the Gizmo and can cost more than the Bark. Buy it for the philosophy, not the price.

What actually decides this purchase

Three questions settle it. First, your child’s age: under 9 points to the COSMO or Gizmo, 9 and up opens the Bark. Second, your carrier: an existing Verizon plan makes the Gizmo’s two-year math very hard to beat. Third, your philosophy on features: if a camera and photo texting sound like the beginning of an argument, Gabb built its watch for you; if they sound like how your kid will actually use the thing, the Bark or COSMO fits better.

What shouldn’t decide it: advertised battery life, as the honesty-gap table shows, and upfront price, which our two-year table demonstrates is the least informative number on the page.

How we compared

We compared current, widely sold kids smartwatches on the factors that decide real purchases: total two-year ownership cost, independently tested battery life, contact and communication features, emergency capabilities, and parental controls. Pricing and tested battery figures come from SafeWise’s January 2026 kids-smartwatch testing roundup, cross-checked against manufacturer pricing pages; our cost and battery-gap tables are our own arithmetic on those published numbers. We don’t claim hands-on testing — we synthesize verified owner feedback, published test data, and expert consensus, and we flag where sources disagree. Read more in our editorial standards.

Frequently asked questions

Do kids smartwatches require a monthly subscription?

Yes — all four watches here need a monthly plan for calling, texting, and GPS, ranging from about $10 to $25 per month. Over two years the plan typically costs two to three times the watch itself, which is why we compare total ownership cost rather than sticker price.

Which kids smartwatch can call 911?

Of this group, the Bark Watch and COSMO JrTrack 5 offer 911 capability. The Gizmo Watch 3 Adventure’s SOS button alerts approved contacts, and per SafeWise’s testing notes the Gabb Watch 3e has no 911 dialing option. Test whichever emergency feature your watch has together with your child.

What age should a kid get a smartwatch?

Most families land between ages 5 and 8 for a first watch, when a child is out of sight at school or activities but too young for a phone. The COSMO and Gabb target that range; the Bark Watch is built for ages 9–14 as a phone alternative.

Can kids smartwatches work without a phone nearby?

Yes. All four are standalone cellular devices with their own service plans — that’s what the monthly fee buys. Your child doesn’t need a phone, and you monitor everything from an app on yours.

Do these watches have cameras and internet access?

None of the four has open internet, an app store, or social media. The Bark (5MP) and COSMO (2MP) include cameras for photo messaging to approved contacts; the Gizmo Adventure and Gabb 3e skip cameras entirely.

Bottom line

Buy the Bark Watch for a 9-to-14-year-old who needs a phone alternative, the Gizmo Watch 3 Adventure if you’re on Verizon and want the lowest true cost, the COSMO JrTrack 5 for a younger kid who’ll grow into its features, and the Gabb Watch 3e if distraction-free is the entire point and you’ve made peace with its emergency-dialing gap.
