Amazfit Band 7 vs Garmin vívofit jr. 3: Best Kids Fitness Tracker

The Bottom Line

For kids ages 4-10, the Garmin vívofit jr. 3 is our clear recommendation. The 1-year battery alone is transformative—no charging routine, no dead watch before school. Add in COPPA-compliant privacy from a US company, proven durability, and kid-specific features, and it's worth the premium.

For teens 12+ who want more features, the Amazfit Band 7 delivers outstanding value. The AMOLED display, heart rate monitoring, and 120 sport modes rival trackers twice the price.

The Privacy Factor

This is the elephant in the room. Amazfit is owned by Huami (now Zepp Health), a Chinese company that:

• Shares data with Xiaomi and "Mi Ecosystem companies"
• Is subject to Chinese "national security requests"
• Received Mozilla's "*Privacy Not Included" rating

Garmin, headquartered in Kansas, offers:

• COPPA-compliant kids privacy policy
• Default "private" settings
• No data sold for advertising
• Parents can use fake names

For your child's biometric data, this matters.

When to Choose Each

Choose Garmin if:

• Child is under 10
• You value privacy and data security
• You hate managing charging routines
• Kids swim regularly
• Durability is important

Choose Amazfit if:

• User is 12+ / teenager
• Budget is the primary constraint
• You want heart rate and advanced metrics
• Privacy concerns are minimal
• You'll use it without the app to limit data transmission
