Design and Comfort of Wearing

In terms of design, the Supersonic Sport smart watch has a sporty yet versatile look. The rounded watch case measures 44mm across and 14mm thick. There are two physical buttons on the right side of the case which are used for navigating through menus and starting/stopping activities.

The included silicone watch band is very soft and flexible, providing a comfortable and breathable fit. It secures with a standard watch buckle and has holes for adjusting the tightness.

Tracking Your Health and Fitness

Health and fitness tracking are two of the main highlights of the Supersonic Sport smart watch. Let’s look at how it performs in these areas:

Heart Rate Monitoring

The optical heart rate sensor on the back of the watch lets you continuously monitor your pulse throughout the day and during workouts. You can view your current heart rate by swiping left on the watch face. The heart rate data is also factored into your overall calorie burn.

During testing, we found the heart rate tracking to be quite accurate when compared against a dedicated heart rate chest strap. Resting heart rate and workout heart rate metrics aligned very closely between the two.

Activity Tracking

For all-day activity tracking, the Supersonic Sport watch uses 3-axis accelerometers and algorithms to detect your steps taken, distance covered, calories burned, floors climbed, and activity minutes. These metrics can all be viewed right on the watch face with a quick swipe.

The watch face will also display motivating messages when you reach certain daily milestones like 250 steps taken or 30 active minutes earned. This can help to keep you engaged throughout the day.

Sleep Monitoring

By wearing the Supersonic Sport watch to bed, you can track your sleep quality and cycles. It monitors sleep duration, continuity, and the time spent in light, deep, and REM sleep stages. You can see your sleep trends and overall sleep score in the companion app.

Built-In GPS for Outdoor Activities

One of the top features of this watch is the built-in GPS, allowing you to accurately track your outdoor activities like running, cycling, and hiking without bringing your phone. The watch connects to GPS satellites quickly to map your route.

In the companion app, you can view an interactive route map of each activity along with additional stats like distance, pace, speed, elevation gain, lap splits, and heart rate zones. For serious athletes, all these metrics are invaluable for tracking progress over time.

Smartphone Connectivity and Notifications

Connecting the watch to your iOS or Android phone is quick and painless via the Supersonic Sport app (compatible with iOS 10.0+ and Android 6.0+). Once paired, you can enable smartphone notifications like calls, texts, calendar events, and social media alerts to appear on your wrist. This allows you to stay connected without constantly checking your phone.

You can also use the watch to remotely control music playback and volume on your phone.To have the  right control on your wrist is super convenient for you, especially for your workouts.

Battery Life and Charging

Supersonic Sport boasts up to 5 days of battery life on a single charge in smartwatch mode. The battery does drain faster when using the GPS functionality. You can expect around 10 hours of continuous GPS usage before needing to charge again.

Charging the watch is easy with the included magnetic charging cable. The charger clips securely onto the back of the watch. It takes about 2 hours to fully charge the watch from empty to 100%.

The battery can last between 3-5 days with light usage. Heavy usage with long daily workouts can reduce battery life closer to 2 days. All in all, the battery life is quite impressive compared to many other full-featured GPS sports watches.

Supersonic Sport App Companion

The Supersonic Sport smart watch pairs with the Supersonic Sport app for iOS and Android. The app provides a seamless way to sync your activity data, customize settings and watch faces, analyze your trends, and share workout achievements.

As soon as you finish an activity on the watch, it will automatically sync your workout data to the app when in Bluetooth range of your phone. The app organizes all your stats by day, week, and month into color-coded graphs and charts. You can also connect third-party apps like Apple Health, Google Fit, or MyFitnessPal to share data.

Overall, the Supersonic Sport app feels very polished and makes it easy to manage your watch settings, activities, and progress.

Accuracy of Stats and Metrics

To provide useful data to users, the accuracy of tracked metrics and stats is critical. During our testing, we found the overall accuracy of the Supersonic Sport’s sensors and tracking to be very good.

The heart rate monitoring proved very accurate against a chest strap monitor. The step counting and distance tracking were also spot-on compared to manual counts and measurements.

For outdoor activity tracking, the built-in GPS allowed for excellent mapping of routes, distances, paces, laps, etc. All the granular workout stats aligned with expectations. The calorie expenditure estimates seemed reasonable as well based on the intensity and duration of activities.

Pricing and Value Proposition

The Supersonic Sport smart watch retails for $179.99 directly from Supersonic. Considering all of the features packed into the watch, including built-in GPS, heart rate monitoring, activity/sleep tracking, music controls, and 5-day battery life, the price is very competitive.

Many comparable GPS sports watches from leading brands cost $300 or more. So in terms of value for money, the Supersonic Sport delivers excellent bang for your buck.
