In-depth reviews
Fitbit Ace 3 review
Who it is for: Parents who want a simple, durable band that encourages daily movement, tracks sleep reliably, and keeps screens to a minimum for kids roughly 6 to 12. It is ideal if you want to avoid subscriptions and still get a friendly app experience.
Key features: The Ace 3 tracks steps, active minutes, and sleep duration with a straightforward, kid-friendly dashboard in the parent app. The soft silicone band is comfortable for small wrists, and the tracker is swimproof to 50 meters so you can leave it on for pool days and showers. Battery life is a standout at up to about a week between charges depending on alerts and animations. The monochrome display is bright and easy to read outside, with fun animated clock faces that reward movement.
How it feels and works: Setup is quick through a supervised child view in the Fitbit app. Kids get move reminders, bedtime nudges, and gentle on-wrist celebrations for hitting goals. Sleep tracking is simple yet useful, showing bedtime, wake time, and total sleep so you can spot patterns and nudge earlier lights-out when needed. There is no heart rate tracking, which keeps things simple and privacy friendly for younger kids.
Drawbacks: No built-in GPS or location features, and no heart rate or advanced sleep stages. If your child responds best to chore charts and screen-time rewards, Garmin’s app ecosystem may be more motivating. If you want calling, messaging, or live location, you will need to look at a kids smartwatch like the Ace LTE or consider a separate phone.
Compared to other picks: Versus the Garmin Vivofit Jr. 3, the Ace 3 offers a sleeker band, easy charging, and particularly friendly sleep tracking. The Vivofit Jr. 3 counters with a year-long replaceable battery and built-in chore rewards. Compared with the Fitbit Ace LTE, the Ace 3 costs far less, does not require a plan, and includes sleep tracking, while the Ace LTE adds kid-first games and location but needs daily charging and a subscription.
Garmin Vivofit Jr. 3 review
Who it is for: Families who love the idea of chore assignments, rewards, and educational mini-adventures built into the app, and who never want to think about charging. It is a great choice for ages 6 to 12 who prefer a set-and-forget band.
Key features: The Vivofit Jr. 3 tracks steps, active minutes, and basic sleep, then pairs that data with the Garmin Jr. app. Parents can assign chores, set timers, and award virtual coins that kids can exchange for real-world rewards you define, like screen time or a trip to the park. A single coin-cell battery lasts up to a year, and the device is water resistant to 5 ATM for swim lessons and splashy bath times. The small color display is always on, so kids can glance at their progress without waking the screen.
How it feels and works: The tracker module pops into themed bands, from space to superhero designs. It is sturdy, light, and comfortable once sized correctly. The on-wrist interface is basic by design, which helps limit distraction. In the app, you can create tasks like brush teeth, read for 20 minutes, or pack backpack, and the tracker can nudge kids with on-screen prompts to complete them.
Drawbacks: There is no heart rate tracking or GPS. The screen is small and not as crisp as adult wearables, and replacing the battery each year is a minor chore. Sleep data is more of the high-level variety, lacking the depth or sleep scoring you will find on teen-focused trackers like the Fitbit Inspire 3. If your child is motivated by games and characters rather than chore charts, the Ace LTE’s arcade approach may be more exciting.
Compared to other picks: Versus the Fitbit Ace 3, the Vivofit Jr. 3 wins on zero charging and built-in household management features. The Ace 3 is better for longer battery per charge, more comfortable fit options, and friendlier sleep tracking visuals. Compared with the Fitbit Inspire 3, the Vivofit Jr. 3 is intentionally simpler and more kid-safe but lacks heart rate and in-depth sleep stages that teens might appreciate.
Fitbit Ace LTE review
Who it is for: Parents who want a kid-first smartwatch that turns movement into games and collectibles, with optional calling, messaging to approved contacts, and location check-ins. It suits families comfortable with a monthly plan and daily charging.
Key features: The Ace LTE adds motion-powered games and characters designed to get kids off the couch and moving to unlock play. With an LTE plan, parents can see location, send messages, and set trusted contacts. The watch is water resistant and built to take a beating from playground tumbles. Activity tracking covers steps and active minutes, and you can schedule quiet times for school.
How it feels and works: It is chunkier than a band-style tracker but still sized for kids, with a bright touchscreen and simple gestures. The arcade-style rewards system makes movement feel like play, which can be powerful for reluctant movers. Parents manage contacts and safety settings in the app and can view activity summaries at a glance.
Drawbacks: The biggest tradeoffs are cost and battery life. You will be charging most nights, and LTE features require a paid plan. It also omits heart rate, calorie burn, and sleep tracking. If sleep insights are a priority or you do not want another monthly subscription, the Fitbit Ace 3 or Garmin Vivofit Jr. 3 are better fits. For older kids who want deeper health metrics, the Fitbit Inspire 3 will make more sense.
Compared to other picks: This is the fun, safety-forward option. It beats the Ace 3 and Vivofit Jr. 3 on location check-ins and kid-first gaming, but those two bands win on price, battery simplicity, and sleep tracking. Compared with the Fitbit Inspire 3, the Ace LTE is more kid-centric and less data heavy, but it lacks the detailed sleep and heart metrics teens may want.
Fitbit Inspire 3 review
Who it is for: Teens or older kids ready for a lightweight band with real health metrics and longer-term habit tracking. It is best for families who do not need kid-specific parental controls but want accurate sleep and heart rate data in a slim, comfortable design.
Key features: The Inspire 3 tracks steps, 24-7 heart rate, resting heart rate trends, sleep stages with a Sleep Score, and can estimate breathing rate and blood oxygen variation during sleep. The AMOLED display is bright yet unobtrusive, and battery life can reach up to 10 days depending on settings. It is swimproof, supports gentle vibration alarms, and delivers phone notifications if enabled.
How it feels and works: The band is very light, fits smaller wrists, and stays comfortable for sleep. The app’s sleep charts and daily readiness-style summaries help teens see how consistent bedtimes change how they feel the next day. If your teen runs or cycles, basic workout modes add context to steps and active time, and heart rate zones give effort feedback.
Drawbacks: Not a kids tracker by design, so you do not get chore systems, location sharing, or a walled garden of approved contacts. It relies on a smartphone for full functionality, which may not be appropriate for younger kids. There is no onboard GPS, though it can use the phone’s GPS for runs and rides. If your priority is playful motivation without constant data, the Ace 3 is simpler.
Compared to other picks: Compared with the Ace 3 and Vivofit Jr. 3, the Inspire 3 offers far richer sleep and heart data, which makes it better for teens. It is less playful than the Ace LTE but avoids monthly service costs and daily charging. For families that want health insights without a smartwatch, it is a strong middle ground.
How to choose
Use these decision points to match a tracker to your kid and your household:
- Age and attention span: Ages 6 to 9 do best with simple bands and on-wrist celebrations. The Fitbit Ace 3 and Garmin Vivofit Jr. 3 are built for this stage. Older kids and teens may want deeper data and a sleeker look, which is where the Fitbit Inspire 3 shines.
- Sleep insights vs. play: If you want bedtime routine help, prioritize the Ace 3 or Inspire 3. If movement-through-games is the hook your child needs, the Ace LTE’s arcade approach is uniquely motivating.
- Charging tolerance: Daily or near-daily charging is normal for smartwatches like the Ace LTE. Weekly charging fits the Ace 3 and Inspire 3. If you prefer to forget about charging altogether, the Vivofit Jr. 3’s year-long coin cell is the winner.
- Safety and connectivity: If you want location check-ins and messaging to trusted contacts without giving your child a phone, consider the Ace LTE and budget for a service plan. If you prefer no connectivity on the wrist, the Ace 3 and Vivofit Jr. 3 keep things simple.
- Motivation style: Chore charts and reward coins point to the Vivofit Jr. 3. On-wrist celebrations and easy goals fit the Ace 3. Data-driven teens who like seeing sleep scores and trends will prefer the Inspire 3.
- Water time and rough play: All four picks are water friendly and durable. If your child swims often or forgets to take devices off, prioritize swimproof models like the Ace 3, Vivofit Jr. 3, and Inspire 3.
- Budget and ongoing costs: Bands like the Ace 3 and Vivofit Jr. 3 offer strong value with no required subscription. The Ace LTE adds monthly service for LTE features. The Inspire 3 may cost a bit more than kids bands but delivers more health data for teens.
Setup, privacy, and healthy use
Start with a quick family chat about why the tracker exists. Make it about feeling strong, sleeping better, and learning routines, not about weight or competition. Agree on reasonable goals, like 8,000 to 10,000 steps for school days, and use streaks or Friday rewards to keep interest without pressure.
Privacy basics: Use the parent app to set up accounts and approve any contacts. If you choose an LTE-enabled tracker, limit who can message your child and review location sharing settings together. For school hours, turn on quiet or school modes to prevent distractions and keep notifications private.
Better data, less fuss: Fit is crucial. Wear the band snug enough that it does not slide around, especially at night, but not so tight that the skin reddens. Set wrist preference correctly, since many kids wear watches on their non-dominant hand. Expect steps to undercount sports with low arm movement, like scooter riding or dribbling a soccer ball. Treat the numbers as coaching signals, not grades.
Care and comfort: Rinse bands after pool time and sweaty practices, then pat dry to prevent skin irritation. Clean the strap weekly with mild soap and water, and rotate between two bands if your child has sensitive skin. Charge during dinner or homework to avoid missing sleep data overnight.
Final thoughts
If you want a dependable kids tracker that nails the basics, start with the Fitbit Ace 3. It gets steps and sleep right, lasts all week, and keeps the focus on healthy habits. If your child thrives on chore charts and you hate charging, go with the Garmin Vivofit Jr. 3. For families who want playful motivation plus location check-ins, the Fitbit Ace LTE is the standout, with the clear tradeoff of daily charging and a monthly plan. And if you have a data-curious teen who will use deeper sleep and heart insights, the Fitbit Inspire 3 is a smart, comfortable upgrade.

The Garmin Vivofit Jr. 3 tracks basic sleep but keeps the focus on routines and chores, and the Fitbit Ace LTE does not track sleep.
Do kids need their own phone to use these trackers?
No. The Fitbit Ace 3 and Garmin Vivofit Jr. 3 work with a parent’s phone and app. The Fitbit Ace LTE can call and message approved contacts and share location without a child phone, but it requires a paid cellular plan.

For sports, using a workout mode on a teen-friendly tracker like the Fitbit Inspire 3 can capture effort beyond steps by tracking heart rate zones.
