FAQ

Support answers for customers and service teams.

What kind of products does BIGGERFIVE make?+

BIGGERFIVE engineers wearable technology for children, especially kids' smart watches and kids' fitness trackers.

Is BIGGERFIVE a medical device?+

No. BIGGERFIVE devices and measurements are intended for general fitness and wellness purposes only. They are not designed to diagnose or treat medical conditions.

What is the return policy?+

BIGGERFIVE provides a 60-day money-back guarantee for undamaged products and a 12-month warranty for quality-related defects.

How do parents manage the devices?+

Parents can use the BIGGERFIVE companion app and Family Account features to bind devices, view activity data, set reminders, manage watch faces, and control game time.

How do you charge the Vigor watch?+

The Vigor tracker uses a built-in USB plug. Remove the watch face from the straps and insert the USB charging plug into a standard USB port. If the charging icon does not appear, flip the plug and insert it in the opposite direction.

How do you change the time?+

Download the BIGGERFIVE app, register an account, turn on Bluetooth, add the device from the app's Device page, select the child account, and bind the bracelet. The time syncs from the phone after binding.

Can I use the tracker separately without connecting it to a phone?+

After initial setup with the BIGGERFIVE app, the tracker can be used independently for steps, calories, heart rate estimates, distance, and active minutes. Sleep detail is stored in the app.

Why does the battery run out quickly?+

Battery life varies by usage. Sport Mode, frequent screen taps, reminders, and other active features can reduce standby time. Turning off unused functions in the app can help the device last longer.

Why does the fitness tracker reset?+

Steps reset when a new day begins. If the device runs out of power, it turns off and restarts when charged, so it may need to reconnect with the phone to sync the time again.

Is it waterproof?+

Yes, supported models are sweat-proof, rain-proof, and splash-proof. Some models support swimming, but long underwater use is not recommended unless the specific product rating supports it.

What phones are compatible?+

The BIGGERFIVE app supports Android 6.0 and above, iOS 9.0 and above, and Bluetooth 4.2. It is not intended for PC, iPad, tablet, or Windows systems. Some US Samsung Galaxy J series phones may not be supported.

How do you remove Vigor watch bands?+

Slide the bands out in a parallel direction. Do not bend the straps up or down while pulling. The first removal can feel tight, but the fit usually loosens over time.
