Zeblaze GTS 4 BT Calling Smart Watch – Full Review
1. Premium and Slim Design
The Zeblaze GTS 4 features a modern, minimalist design that complements both casual and formal outfits. Its metal-alloy frame gives the watch a premium appearance, while the approximately 8.7 mm slim body helps maintain a comfortable fit throughout the day.
The comfortable liquid-silicone strap is suitable for everyday wear, work, walking, and exercise. Depending on availability, customers may find the watch in Midnight Black, Champagne Gold, and Starlight Silver.
2. 1.94-Inch HD AMOLED Display
One of the standout features of the Zeblaze GTS 4 is its 1.94-inch AMOLED touchscreen. With a resolution of 466 × 466 pixels and a pixel density of approximately 391 PPI, the display delivers sharp text, clear icons, and vibrant colours.
The AMOLED panel makes notifications, watch faces, health information, and workout data easy to view. Its touchscreen interface and rotating crown provide convenient navigation through menus and smartwatch functions.
Selected product listings also specify brightness of up to 1,000 nits and Always-On Display support. Availability of display options can depend on the exact product version, so confirm these features before purchase.
3. Bluetooth Calling Function
The Zeblaze GTS 4 supports Bluetooth calling through its built-in microphone and speaker. Once paired with a compatible smartphone, users can answer incoming calls and place calls using the watch’s available calling interface.
This feature is useful when your phone is in your bag, on your desk, or otherwise not immediately accessible. It can make everyday communication more convenient at work, at home, or while walking.
Please note that this is a Bluetooth-connected smartwatch rather than a standalone cellular watch. Calling requires a compatible paired phone and an active Bluetooth connection.
4. Smart Notifications and Everyday Convenience
The watch helps you stay updated by displaying supported smartphone notifications on your wrist. Depending on your phone, app permissions, and connection settings, you can receive alerts for calls, SMS messages, and compatible applications.
Additional convenience features include music control, remote camera control, an alarm, a stopwatch, weather information, a phone-finding function, and voice-assistant support. These tools make the smartwatch useful beyond fitness tracking.
5. Health Monitoring Features
The Zeblaze GTS 4 includes several features designed to help users understand their daily activity and general wellness.
- Heart rate monitoring for checking pulse readings.
- Blood oxygen (SpO2) measurement for wellness reference.
- Sleep monitoring to review sleep patterns and duration.
- Breathing exercises to support relaxation routines.
- Women’s health tracking features.
- Activity and calorie tracking to help monitor daily movement.
These features can help users follow general wellness trends over time. However, smartwatch health readings are estimates and should not replace medical tests, professional diagnosis, or treatment.
6. More Than 100 Sports Modes
The Zeblaze GTS 4 supports more than 100 sports and activity modes, making it suitable for users who want to track a variety of workouts. Depending on the selected activity mode, the watch can record relevant exercise information and help users review their activity history.
It can be useful for walking, running, gym sessions, and other supported activities. For the best tracking experience, wear the watch securely and ensure the required permissions and settings are enabled in the companion app.
7. Battery Life and Charging
The Zeblaze GTS 4 uses a 300 mAh battery and magnetic charging. Published specifications indicate approximately five days of battery life under heavy use, seven days under typical use, and up to 14 days in battery-saver mode.
Actual battery performance varies with Bluetooth calling, screen brightness, display settings, health monitoring, notifications, and overall usage. Frequent calls and continuous use of power-intensive features may reduce battery life.
The stated charging time is approximately two to three hours in several retailer listings. Charging time can vary depending on the charger, power source, and battery condition.
8. Water Resistance
The Zeblaze GTS 4 is listed with an IP68 water-resistance rating. This rating provides protection under specified laboratory conditions, but it should not be interpreted as unlimited waterproofing.
Avoid assuming the watch is suitable for swimming, diving, hot showers, or high-pressure water exposure. Follow the manufacturer’s instructions and warranty terms, particularly when using the watch around water.
9. Smartphone Compatibility and FitCloudPro App
The Zeblaze GTS 4 supports compatible Android and iOS smartphones and works with the FitCloudPro companion app. Commonly listed minimum requirements are Android 5.0 or later and iOS 10.0 or later.
The app can help users pair the watch, configure supported notifications, review activity information, and customize available watch faces. Compatibility with individual phones and app features may vary according to operating-system versions and software updates.
