| Daily moderate-to-vigorous physical activity |
Children and adolescents aged 5–17 should average at least 60 minutes per day of moderate-to-vigorous physical activity across the week. |
Displays accumulated active minutes and helps children recognize progress toward the daily target. |
Look for clear daily activity summaries and age-appropriate progress indicators. |
| Weekly consistency |
The WHO benchmark is expressed as an average across the week, so regular activity on multiple days is preferable to concentrating activity on one day. |
Weekly activity history can reveal patterns such as inactive weekdays or highly active weekends. |
Choose a device that presents seven-day trends rather than only one-day totals. |
| Higher-intensity activity |
WHO recommends incorporating vigorous-intensity aerobic activities, plus muscle- and bone-strengthening activities, at least 3 days per week for ages 5–17. |
Exercise modes, heart-rate trends, or intensity zones may help identify active periods, although they should be treated as estimates. |
Use activity data as feedback, not as a medical measurement or performance diagnosis. |
| Outdoor and water-based play |
Swimming, water games, cycling, running, and active outdoor play can contribute to physical activity, depending on intensity and duration. |
A water-resistant design can reduce concern during handwashing, rain, and suitable water-related activities. |
Verify the exact water-resistance rating and permitted use; “water-resistant” does not automatically mean suitable for swimming or diving. |
| Water-resistance interpretation |
Under IEC 60529, IPX7 generally refers to temporary immersion in up to 1 metre of water for up to 30 minutes under specified laboratory conditions; IPX8 conditions are manufacturer-defined. |
Supports more confident use during everyday active routines when the device rating matches the activity. |
Check the official rating, test conditions, water temperature limits, and whether buttons may be used underwater. |
| Progress feedback |
The WHO recommendation is a population-level health guideline, not a pass-or-fail test for an individual child. |
Gentle reminders and visual goals can encourage movement without turning activity into excessive competition. |
Prefer adjustable goals, positive notifications, and the ability to disable unnecessary alerts. |
| Data accuracy and limitations |
Consumer wearable estimates can vary by device, body movement, fit, activity type, and algorithm; they should not replace professional assessment. |
Provides useful direction for routines and habits when viewed over time rather than as exact clinical data. |
Use trends for encouragement, and consult a qualified professional about health concerns or unusual symptoms. |
| Privacy and responsible use |
Activity information may be sensitive, particularly when combined with location or communication features. |
Can support family discussions about healthy routines while allowing adults to review permissions and data sharing. |
Review privacy controls, location settings, account security, data retention, and child-safety features before use. |
