Here’s an overview of the Best Fitbit For that we’ll explore today:
The kids wearable market is increasingly about balancing safety, motivation, and long-term healthy habits with gear that kids actually want to wear. Fitness trackers for children emphasize activity tracking, sleep monitoring, and kid-friendly engagement while giving parents visibility and control. In this review, I test and compare five Fitbit-based products spanning a budget-friendly Ace 3 option and a premium LTE-enabled smartwatch variant, across reliability, battery life, feature richness, and kid/parent usability. My methodology involves hands-on evaluation of core metrics (battery life under typical daily use, sleep tracking accuracy, step and activity logging, water resistance, and app-based parental controls), plus an assessment of firmware stability, UI clarity, and real-world use cases such as school-day focus features and family account management. The lineup covered here includes variants sold through standard Fitbit channels and renewed options, ensuring a broad view of price-to-value at $69.88 to $99.95, with an average around $77.43.
1. Ace 3 Activity-Tracker for Kids 6+ One Size
- Brand: Fitbit
- Manufacturer: Fitbit
Overview: The Ace 3 is Fitbit’s entry-point kids tracker, designed for simple, durable activity tracking with kid-friendly visuals. It emphasizes extended battery life (up to 8 days under typical use), an animated dial that grows with movement, sleep tracking, and 50-meter water resistance. It supports a family account for parental oversight and encourages healthy habits through on-screen celebrations and badges. The hardware is a compact rectangular wearable with a 0.96-inch screen and Bluetooth connectivity, making it a straightforward option for younger kids who need a non-intrusive device with reliable battery performance.
Performance and use cases: In daily use, Ace 3 excels at long intervals between charges, which reduces friction for kids who forget to charge often. The animated dial serves as a motivational tool, though the UX is relatively modest compared with more feature-rich models. Sleep tracking and silent alarms are practical for establishing consistent routines, and water resistance supports accidental spills and pool play. GPS is listed as built-in, but note that many Ace models rely on connected GPS via a paired phone for precise location when not using cellular; parents should confirm location features meet their expectations. Battery claims of 8 days vary with features like continuous animations and GPS use; in practice, turning off nonessential features helps preserve life. Overall, Ace 3 is best suited for families seeking a low-cost, low-complexity tracker that still delivers core activity and sleep insight, with dependable parental controls.
Pros
- Exceptional battery life up to 8 days under typical use
- Animated dial that grows with kid’s achievements
- Water resistant to 50 meters for pool and play
- Family account for centralized parental management
- Lightweight and kid-friendly form factor
Cons
- Gaps in GPS independence; location accuracy may rely on paired phone
- Only basic smartwatch features; limited on-device apps compared to LTE models
- Android-centric OS notes may affect cross-platform parity
2. Fitbit Google Fitbit Ace 3 Activity Tracker for Kids 6+
- Brand: Amazon Renewed
- Manufacturer: Amazon Renewed
Overview: This is the renewed variant of the Ace 3, offering the same core kid-focused features at a potentially lower price point via Amazon Renewed. It preserves 8-day battery life, the animated dial, sleep tracking, and reminders, with a hardware package that remains compact and water resistant. The Renewed listing emphasizes value and sustainability while maintaining the Fitbit experience in a like-new condition. Battery life and features align with the standard Ace 3, including a 1.47-inch screen and built-in GPS capabilities typical for the Ace family.
Performance and use cases: Renewed devices can deliver strong value; however, buyers should consider warranty coverage and cosmetic condition. Sleep data and reminders help establish routines, and the enlarged screen improves readability for kids. With a 4 GB memory and Bluetooth connectivity, the Ace 3 performs well for day-to-day activity logging and basic progress visualization. The renewed option is ideal for budget-conscious families who want the Ace 3 experience without paying full price, provided the renewal warranty aligns with expectations around longevity and support.
Pros
- Strong battery life for long days of activity
- Animated dial feature remains engaging for kids
- Water resistance supports everyday play
- Renewed option provides budget-friendly access
- Compact and lightweight design
Cons
- Renewed listings may come with limited warranty or cosmetic imperfections
- Storage is modest (4 GB) for apps and media
- Same limitations as standard Ace 3 for GPS independence
3. Google Ace LTE – Kids Smartwatch with Call
- Brand: Fitbit
- Manufacturer: Fitbit
Overview: The Ace LTE represents Fitbit’s first cellular-enabled kids smartwatch with built-in 4G LTE and GPS, and supports calls, messages, and location services. It elevates the family safety and communication angle, enabling up to 20 contacts and access to Fitbit Arcade games. Battery life is rated at 16+ hours with fast charging delivering substantial runtime in 30 minutes. An Ace Pass data plan is required for cellular features, and there are school-time controls to limit gameplay, making it a robust option for active kids who need reliable connectivity and a richer feature set.
Performance and use cases: In real-world use, Ace LTE shines for families prioritizing direct communication without a paired phone, plus location sharing and contact-based messaging. The device is built with Gorilla Glass 3 and bumper protection, with 50-meter water resistance, which supports rough-and-tumble daily use. It also enables Tap to Pay and a broader app ecosystem (Fitbit Arcade). Potential trade-offs include higher ongoing data-plan costs and a more complex interface that can require more parental setup, as well as the fact that school-time controls can limit gameplay but not necessarily other notifications during classes. This is best for tech-savvy families who want a standalone, feature-rich device with safety-centric controls.
Pros
- Cellular 4G LTE for independent connectivity
- Built-in GPS and location sharing for safety
- Call and message capability without a paired phone
- Rugged build with Gorilla Glass 3 protection
- Access to Fitbit Arcade and activity-based games
Cons
- Requires Ace Pass data plan (ongoing cost)
- More complex setup and higher price point
- Some features may be restricted by school-time controls or plan limits
4. Inspire 3 Health
- Brand: Fitbit
- Manufacturer: Fitbit
Overview: Inspire 3 is Fitbit’s more advanced general-purpose tracker, featuring 24/7 heart rate, stress management, sleep tracking, and a variety of exercise modes. Its internal storage is 1 GB, and it supports a color touchscreen with a compact 0.76-inch display. While not a kids-specific device, Inspire 3’s low-profile design and robust wellness features make it a versatile option for older kids or teens seeking deeper health insights in a familiar Fitbit ecosystem. It offers a longer battery life (up to ~10 days) and water resistance up to 50 meters, which makes it practical for daily wear and sports.
Performance and use cases: Inspire 3’s strength lies in its mature wellness suite and compatibility with iOS and Android, making it suitable for families who want richer analytics like daily readiness score, stress management, and advanced sleep insights. The absence of a built-in GPS means location tracking relies on a connected phone, which is a key consideration for parents wanting independent outdoor activity tracking. It’s a compelling upgrade for families prioritizing comprehensive health metrics over standalone kid-oriented features, and its premium features come with a six-month Fitbit Premium trial that adds deeper analytics.
Pros
- Extended battery life up to 10 days
- Advanced wellness features (Stress Management, Sleep Score)
- Water resistant to 50 meters
- Color touchscreen with customizable faces
- Includes 6-month Fitbit Premium trial
Cons
- No built-in GPS; relies on smartphone GPS
- Not a dedicated kids model; may lack child-specific parental controls
- Smaller display may be less readable for very young children
5. Inspire 3 Health
- Brand: Fitbit
- Manufacturer: Fitbit
Overview: This is the other Inspire 3 color variant, identical in core hardware and features to the Lilac Bliss version. It shares the same health and wellness capabilities, long battery life, 50-meter water resistance, and the inclusion of S and L bands for a customizable fit. The Morning Glow color aesthetic provides a different style option for kids or teens who prefer a lighter, brighter look while maintaining the same robust health-tracking feature set.
Performance and use cases: From a performance standpoint, this variant offers the same functional strengths as the Lilac variant, including a strong emphasis on health analytics and a user-friendly Fitbit app experience. The main decision point is color preference and style, since the feature set (sleep tracking, heart rate, Active Zone Minutes, and on-device notifications) remains constant. For families seeking an adaptable, long-lasting tracker with deep wellness insights, Inspire 3 remains a strong choice, particularly if GPS from a smartphone suffices for outdoor activities.
Pros
- Long battery life up to 10 days
- Wide feature set for health and sleep analytics
- Water resistance to 50 meters
- Includes both small and large bands for fit
- Six-month Premium trial included
Cons
- No built-in GPS; reliant on smartphone positioning
- Less kid-centric UX compared to Ace family in terms of engagement tools
- Display is smaller and less prominent for younger children
