The Fitbit Ace LTE is Google’s answer to the kids smartwatch market. It launched in mid 2024 and targets children ages 7 to 11. This watch combines LTE calling, GPS tracking, and activity based games into one colorful package.

The Ace LTE has a square shaped design with a Corning Gorilla Glass 3 protected OLED display. It weighs about 28 grams without the band, making it lighter than the Garmin Bounce 2. Google designed it with fun and movement as the core idea. The Fitbit Arcade offers games that require physical activity to play.

Parents use the Fitbit Ace app to manage contacts, set school time restrictions, and track location. The watch supports up to 20 approved contacts for calling and messaging. It also has an optical heart rate sensor, which the Garmin Bounce 2 lacks.

• Lightweight at just 28 grams

Cons:

• Battery lasts only 16+ hours

Design and Build Quality

Both watches are built for active kids, but they take different design paths. The Garmin Bounce 2 has a round watch face with a 43mm fiber reinforced polymer case. It feels sporty and rugged on the wrist. The physical buttons give kids a tactile way to navigate alongside the touchscreen.

The Fitbit Ace LTE has a square display with rounded corners. It uses a mix of plastic, stainless steel, and recycled materials. The Corning Gorilla Glass 3 protects the screen from scratches and bumps. Both watches use silicone bands that are comfortable for small wrists.

The Garmin Bounce 2 weighs 40.4 grams with the strap while the Fitbit Ace LTE weighs about 28 grams without the band. The Fitbit is noticeably lighter. For smaller kids, the Fitbit may feel more comfortable for all day wear. Both watches come in fun color options that appeal to children.

Display Comparison

The screen is where kids spend most of their time, so display quality matters. The Garmin Bounce 2 uses a 1.2 inch AMOLED display that delivers vibrant colors and deep blacks. It performs well under direct sunlight, which is important for outdoor play.

The Fitbit Ace LTE features a 1.61 inch color OLED display with a 333 ppi pixel density and DCI P3 color support. This screen is larger and sharper than the Garmin’s display. Text, icons, and game graphics look crisp and colorful on the Fitbit.

For kids who play interactive games on their watch, the Fitbit’s bigger screen provides a better experience. For kids who mainly use the watch for calls, texts, and sports tracking, the Garmin’s AMOLED display is more than good enough. Both screens handle everyday tasks like reading messages and checking the time with ease.

Battery Life: A Major Difference

Battery life is one of the biggest differences between these two watches. The Garmin Bounce 2 delivers up to 2 days of battery life on a single charge. This means your child can wear it through a full day of school, activities, and sleep without needing the charger every night.

The Fitbit Ace LTE lasts about 16+ hours on a full charge. That means it needs to charge every single night. If your child forgets to charge it, the watch will be dead by the next afternoon. The Fitbit does charge fast though. You get 60% in just 30 minutes with the USB C cable.

For busy families, the Garmin’s longer battery life is a clear advantage. Less charging means fewer chances of your child leaving the house with a dead watch. This is especially important for safety features like GPS tracking and emergency calls that only work when the watch is powered on.

GPS and Location Tracking

Both watches use GPS and LTE for real time location tracking. Parents can open the companion app and see exactly where their child is on a map. The Garmin Bounce 2 uses the Garmin Jr. app and the Fitbit Ace LTE uses the Fitbit Ace app for this purpose.

The Garmin Bounce 2 offers geofencing through its boundary alerts feature. Parents can set safe zones like home, school, or a friend’s house. The watch sends an alert when the child enters or leaves these zones. Garmin also offers LiveTrack, which shows your child’s location in real time during activities.

The Fitbit Ace LTE provides GPS location tracking with Google Location Accuracy built in. Parents can check their child’s location from the app at any time. Both watches perform well for location tracking, but Garmin’s geofencing and LiveTrack features give it a slight edge for parents who want extra control and visibility.

Calling and Messaging Features

Both watches let kids call and text without a smartphone. The Garmin Bounce 2 supports two way calling, text messaging, and voice messages over LTE. Parents approve all contacts through the Garmin Jr. app. Kids can type short texts or send voice messages that get transcribed for parents.

The Fitbit Ace LTE supports calling and messaging with up to 20 approved contacts. It also runs on 4G LTE with a SIM card included in the watch. Parents control the contact list through the Fitbit Ace app.

Both watches require a monthly subscription for LTE features. Garmin charges $9.99 per month or $99 per year. Fitbit charges $9.99 per month or $119.99 per year. The annual subscription costs are similar, but Garmin’s yearly plan is slightly cheaper. Neither watch lets kids access the internet or social media, which is a relief for most parents.

Fitness and Activity Tracking

The Garmin Bounce 2 shines with its built in sports apps. Kids can track activities like running, biking, swimming, hiking, and more. The watch records steps, distance, and active minutes. Garmin also includes chore tracking and reward systems through the parent app. These gamification features encourage kids to stay active and complete tasks.

The Fitbit Ace LTE takes a different approach with its Fitbit Arcade. This collection of games requires physical movement to play. Kids earn points and unlock new content by being active. The optical heart rate sensor adds real time heart rate tracking during exercise and rest.

The Garmin is better for kids who play organized sports and want detailed activity data. The Fitbit is better for kids who need motivation through games to get moving. The heart rate sensor on the Fitbit is a meaningful bonus for parents who want to monitor their child’s health metrics over time.

Parental Controls and Safety

Safety is the main reason parents buy kids smartwatches. The Garmin Bounce 2 offers a comprehensive set of parental controls through the Garmin Jr. app. Parents can approve contacts, set boundary alerts, activate school mode, and view location history. The watch also features an SOS button for emergencies.

The Fitbit Ace LTE has a School Time mode that limits watch functions during school hours. Parents can control contacts, view location, and manage settings from the Fitbit Ace app. The watch does not allow internet browsing or social media access.

Both watches give parents strong control over what their child can do. Garmin’s boundary alerts and LiveTrack provide slightly more detailed location monitoring. Fitbit’s School Time mode is simple and effective. Neither watch exposes children to ads, inappropriate content, or unsupervised communication. Both are COPPA compliant and built with child privacy in mind.

Games and Entertainment

The Fitbit Ace LTE wins the entertainment category with its Fitbit Arcade. These activity based games use the watch’s sensors to track movement. Kids interact with virtual characters called eejies and complete physical challenges. The games are colorful, engaging, and well designed for the target age group.

The Garmin Bounce 2 offers fewer games but includes some fun features. Kids can earn badges and rewards for completing activity goals and chores. The watch also supports Amazon Music, which lets kids download and listen to playlists offline. This is a feature the Fitbit Ace LTE does not offer.

If your child values gaming and interactive fun, the Fitbit delivers a richer experience. If your child prefers music and straightforward activity goals, the Garmin is the better choice. The good news is that neither watch offers addictive screen time like a phone or tablet would.

Water Resistance

Both watches can handle water. The Garmin Bounce 2 has a 5 ATM water resistance rating. This means it can survive depths of up to 50 meters. Kids can wear it while swimming, playing in sprinklers, or taking a shower without any worry.

The Fitbit Ace LTE also carries a 5 ATM water resistance rating. It handles pool time, rain, and accidental splashes equally well. Both watches use materials that resist corrosion from chlorine and salt water.

The Garmin Bounce 2 has a small advantage here because it includes a dedicated swim sport app. Kids can actually track their swimming activity with the Garmin. The Fitbit can survive water but does not offer a swim tracking mode. For families who spend a lot of time at the pool or beach, this is a meaningful difference.

Subscription Plans and Total Cost

The upfront price is only part of the equation. The Garmin Bounce 2 costs $299.99 and requires a $9.99/month subscription plan ($99/year). In the first year, you will spend about $419.87 if you pick the monthly plan.

The Fitbit Ace LTE costs $229.99 and also requires a $9.99/month Ace Pass plan ($119.99/year). Your first year total comes to about $349.87 on the monthly plan.

The Fitbit is $70 cheaper upfront and costs slightly less over the first year. However, the Garmin’s annual plan at $99/year is $20 cheaper per year than Fitbit’s $119.99/year plan. Over two or three years, this gap narrows. Both subscriptions cover LTE service, calling, messaging, and location tracking. Neither watch requires you to switch phone carriers, which keeps setup simple.

Which Watch Should You Buy?

The right choice depends on your child’s age, interests, and your family’s priorities. Pick the Garmin Bounce 2 if your child is active in sports, you want longer battery life, and you value detailed location features like geofencing and LiveTrack. It is also the better pick for swimmers and outdoor adventurers.

Pick the Fitbit Ace LTE if you want a lower upfront cost, built in heart rate monitoring, and fun activity games that keep younger kids engaged. It is ideal for kids ages 7 to 11 who respond well to gamified fitness challenges and need a lightweight watch.

Both watches deliver solid calling, messaging, and GPS tracking. Both keep kids off smartphones while staying connected. You cannot go wrong with either choice. The key is to match the watch with your child’s personality and your parenting style.
