Introduction

BIGGERFIVE is a free companion app for BIGGERFIVE smartwatches and fitness trackers, developed by BIGGERFIVE TECHNOLOGY CO., LIMITED (Hong Kong). With over 100,000 downloads on Google Play and a 4.2-star rating (1,200+ reviews), the BIGGERFIVE app connects your wearable device via Bluetooth to track daily activity, monitor health metrics, and manage family fitness — all without subscription fees.

The BIGGERFIVE app pairs with popular models including the Brave 2, Brave 3, Vigor, Vigor 2, Vigor 2L, Vigor 3, BW01, and BW02 kids smartwatches. It serves as the central hub for syncing, visualizing, and analyzing health data for kids and adults alike.

How the BIGGERFIVE App Works

The BIGGERFIVE app connects to your BIGGERFIVE watch via Bluetooth Low Energy (BLE). Once paired, it continuously syncs health data — steps, distance, calories, heart rate, SpO₂, and sleep stages — from your wearable to your phone. Data is displayed in daily, weekly, and monthly summaries with clear charts.

The app also acts as a notification bridge: incoming calls, SMS, and app alerts are forwarded to your BIGGERFIVE smartwatch. You can customize watch faces, set alarms, configure reminders, and manage family accounts — all from a single interface.

Health & Fitness Tracking

Step Counting & Activity

The BIGGERFIVE app tracks your daily steps, distance walked, and calories burned in real-time through your connected wearable. Set personalized activity goals and follow your progress with clear daily summaries.

Sleep Monitoring

Wearing your BIGGERFIVE fitness tracker to bed enables detailed sleep tracking — including deep sleep, light sleep, and REM stages. View sleep duration and quality trends over time to understand and improve your rest patterns.

Heart Rate & SpO₂

For compatible devices like the Brave 2 and Vigor 2, the app records heart rate and blood oxygen saturation (SpO₂) estimates throughout the day and during workouts. These readings help you understand effort and recovery trends. All measurements are for general wellness purposes only — not medical diagnosis.

Workout Tracking

Record your workouts with duration, pace, and activity routes (when available on your device). The app supports walking, running, and cycling modes with GPS tracks and speed monitoring.

Family Mode & Kids Features

BIGGERFIVE is designed with families and kids in mind. Key family features include:

Family accounts — manage multiple BIGGERFIVE watches for different family members
Parental controls — monitor your child's activity, sleep, and device usage
Achievement sharing — share weekly activity summaries with friends and family
Virtual medals — kids earn medals for reaching milestones, keeping them motivated

The BIGGERFIVE Brave 2 (IP68 waterproof) and BW02 nylon-band models are especially popular as kids smartwatches that parents can monitor through the app.

Smart Notifications & Customization

Call & Message Alerts

The BIGGERFIVE app forwards incoming calls and message notifications directly to your smartwatch, so you can see who's calling or messaging without picking up your phone.

Watch Face Gallery

Personalize your BIGGERFIVE watch with a variety of watch faces from the built-in gallery. Sync your favorite designs to your wearable for a fresh look every day.

Lifestyle Reminders

Configure sedentary reminders, exercise reminders, water reminders, and custom alarms. Two-way alarm syncing keeps your phone and watch in sync.

The BIGGERFIVE app works with the full range of BIGGERFIVE smartwatches and fitness trackers:

Brave 2 — IP68 waterproof kids smartwatch with GPS and activity tracking

Vigor 2L — larger display variant of the Vigor 2
Vigor 3 — latest generation with optimized performance

How do I connect the BIGGERFIVE app to my smartwatch?

To connect: (1) Download the BIGGERFIVE app from Google Play or App Store; (2) Open the app and register an account (or use visitor login); (3) Enable Bluetooth on your phone; (4) Power on your BIGGERFIVE watch; (5) In the app, go to the device section and tap 'Add Device'; (6) Select your watch model (Brave 2, Vigor 2, etc.) from the scan list and confirm pairing; (7) Grant notification and location permissions when prompted. Keep both devices close during initial pairing.

Why is my BIGGERFIVE watch not connecting or keeps disconnecting?

Common fixes: (1) Ensure Bluetooth is enabled on your phone; (2) Keep devices within close range during pairing; (3) If the watch dies or goes out of range, restart your phone and reconnect via Bluetooth; (4) Clear the app cache — go to Settings > Apps > BIGGERFIVE > Storage > Clear Cache; (5) Update to the latest app version from the store; (6) Remove the watch from other phones' Bluetooth settings first; (7) On Android, disable battery optimization for BIGGERFIVE to prevent background termination.

Which smartwatches are compatible with the BIGGERFIVE app?

The BIGGERFIVE app works with all BIGGERFIVE smartwatches and fitness trackers including: Brave 2 (IP68 waterproof kids smartwatch), Brave 3 (latest kids model), Vigor (fitness tracker), Vigor 2, Vigor 2L (larger display), Vigor 3 (latest generation), BW01 (compact kids tracker), and BW02 (nylon-band kids smartwatch). If your watch's packaging mentions 'BIGGERFIVE,' it's compatible.

Does the BIGGERFIVE app sync with Apple Health?

Yes. BIGGERFIVE integrates with Apple Health (HealthKit) on iOS devices. The app syncs steps, calories, and sleep data to Apple Health. To enable: open the BIGGERFIVE app, go to settings, find the Apple Health / HealthKit option, and grant permission. This allows you to view your BIGGERFIVE data alongside other health apps. Note: Apple Health sync is iOS-only.

Is the BIGGERFIVE app free to use?

Yes, the BIGGERFIVE app is completely free to download and use on both Android and iOS. There are no subscription fees, premium tiers, or in-app purchases. All features — health tracking, notifications, watch face gallery, family accounts, and goal setting — are included at no cost.

How does family mode work in the BIGGERFIVE app?

Family mode lets you manage multiple BIGGERFIVE watches for different family members from a single account. You can bind multiple devices, set up kid accounts with parental controls, and monitor each child's activity, sleep, and device usage. Note: currently switching between watches requires disconnecting one before connecting another — the developer is improving multi-device support.

How do I change the time on my BIGGERFIVE watch?

Your BIGGERFIVE watch automatically syncs its time with your connected phone via the BIGGERFIVE app. To update the time: (1) Open the BIGGERFIVE app; (2) Ensure your watch is connected via Bluetooth; (3) The time will automatically sync to match your phone.

How do I reset my BIGGERFIVE watch?

To factory reset your BIGGERFIVE watch: (1) On the watch, navigate to Settings > System > Factory Reset; (2) Confirm the reset. For the Vigor 2, you can also reset without the app by holding the button for 10+ seconds. After resetting, re-pair the watch with the BIGGERFIVE app to restore your settings. Note: a factory reset erases all data on the watch.

What health metrics can the BIGGERFIVE app track?

The BIGGERFIVE app tracks: daily steps, walking distance, calories burned, heart rate, blood oxygen saturation (SpO₂), and sleep stages (deep, light, REM). You can set personalized goals for steps and other metrics. The app also supports workout tracking for walking, running, and cycling with GPS routes. All readings are for general wellness reference only — not medical diagnosis.

User Reviews

Gracie Staren

App Store

I love this watch... tracks sleep, steps, heart rate, calories. Perfect watch for ages 5-16. The app is organized and productive. My daughter wears it every day and loves checking her step count. Great value compared to Fitbit for kids.

ThaddeusTheGreat777

App Store

Game-changer for our family. Motivated to move more, stress less, sleep better. My doctor even noted significantly improved health markers. The BIGGERFIVE app tracks everything clearly and the watch face options are fun. Highly recommend.

Great app overall. The interface can be a bit hard to navigate at first but once you figure it out it works well. Love the watch for my kids. Would appreciate a vibration-only alarm mode and a better tracker feature for seeing historical data.

Lil12348

App Store

Cool product. The step tracking and heart rate features work well. Main issues are that you can't reply to messages from the watch and syncing takes a while sometimes. Needs some improvement but does the basics well for the price.

Kjule

App Store

The app could be more user friendly. Login process is frustrating when managing multiple kids' watches — have to log out and log back in. The watches themselves are great quality though and tracking features work accurately. Hoping for app updates.

Tamara Hill

Google Play

At first I was having buyer's regret. My daughter loves the watch and it helps her remember things. The app itself is easy to use. If the watch dies or disconnects, restart your device and reconnect via Bluetooth. A bit of a pain, but it works. Info stays stored on the app account.

Andrew Uden

Google Play

The BIGGERFIVE watches themselves work fine and seem well made for kids to wear. The family account feature needs improvement — the app only recognizes one watch at a time. I bought 2 Vigor 2 watches for my kids but can only configure one at a time. Potential is there, developer needs to improve multi-device support.

Shay P.

Google Play

I love this app. I have a Fitbit too but the BIGGERFIVE is great for my kid. Every time you go in the app it needs Bluetooth connected but it's easy to connect. It tracks beats per minute accurately. You have a stopwatch and a parent can control things. Highly recommend.

Good companion app for my kid's Brave 2 watch. Sleep tracking shows deep and light sleep stages which is helpful. Step counting is accurate — we compared it with my Fitbit and it was very close. The watch face gallery has fun designs my daughter loves. Free and no ads.

David K.

Google Play

Works well for our family. The Vigor 3 pairs quickly via Bluetooth and heart rate readings are consistent. Sedentary reminders help keep the kids active during homework time. Apple Health sync works on my wife's iPhone. Would be great if they added Google Fit integration too.
