Whether you are a complete beginner or a tech enthusiast looking to squeeze every bit of performance from your wearable, this CN6 square smartwatch guide delivers actionable insights backed by real-world experience.
What Is the CN6 Square Smartwatch?
The CN6 square smartwatch is a feature-rich fitness band styled with a square watch face, bridging the gap between traditional fitness trackers and full smartwatches. Unlike round smartwatches that mimic classic wristwatch aesthetics, the square design of the CN6 maximizes screen real estate for notifications, workout metrics, and health data visualization. It typically runs on a lightweight proprietary operating system and pairs via Bluetooth with both Android and iOS devices.
Key highlights that set the CN6 apart include a high-resolution LCD display with always-on capability, a built-in heart rate monitor, SpO2 blood oxygen sensing, sleep tracking, multi-sport exercise modes, and a rechargeable battery that often lasts between five and seven days depending on usage intensity. The square form factor also makes it easier to read watch faces at a glance compared to many round competitors in the same price bracket.
Who Should Buy the CN6 Square Smartwatch?
This device appeals to a wide audience. Fitness beginners will appreciate the intuitive interface and guided workout prompts, while intermediate users can dig into detailed sleep stages and heart rate zone analysis. Even advanced users who want a secondary wearable for daily activity tracking without the premium price tag of brands like Apple or Garmin will find the CN6 compelling.

Getting Started with Your CN6 Square Smartwatch
Setting up the CN6 square smartwatch is straightforward, but following the correct sequence ensures optimal performance from day one. Begin by charging the device fully using the included magnetic charging cable. A full charge typically takes about two hours. Once powered on, download the companion app — usually available as “FitPro,” “GloryFit,” or a brand-specific app depending on your region — from the Google Play Store or Apple App Store.
- Enable Bluetooth on your smartphone
- Open the companion app and create or log into your account
- Tap “Add Device” and select the CN6 from the discovered devices list
- Confirm the pairing code displayed on both the watch and your phone
- Complete the initial profile setup, including height, weight, age, and fitness goals

Expert tip: During the first pairing, keep your phone within one meter of the watch to avoid connection drops. The CN6 square smartwatch uses Bluetooth 5.0 or later, which offers significantly better range and stability compared to older versions.
CN6 Square Smartwatch Features Deep Dive
Health Monitoring Capabilities
The CN6 excels at continuous health tracking. The optical heart rate sensor provides real-time BPM readings during exercise and passively monitors your resting heart rate throughout the day. The SpO2 sensor measures blood oxygen saturation levels, which can be particularly useful during sleep or at high altitudes. The sleep tracking algorithm analyzes movement patterns and heart rate variability to classify sleep stages accurately.
Fitness and Workout Modes
Most CN6 square smartwatch models support between eight and twelve sport modes, including outdoor running, treadmill walking, cycling, swimming (with water resistance up to 50 meters), badminton, and yoga. Each mode tracks specific metrics like pace, distance, calories burned, and heart rate zones. The watch can also auto-detect certain exercises, saving you the trouble of manually starting a session every time.
Smart Features and Connectivity
Beyond fitness, the CN6 functions as a mini smart device on your wrist. You can receive call reminders, text notifications, and app alerts from WhatsApp, Facebook, Instagram, and more. The built-in weather widget, stopwatch, timer, and alarm clock add everyday utility. Some variants even support a find-phone feature, music control, and sedentary reminders that prompt you to stand up and move after prolonged sitting.

Advanced Tips and Customization
Changing Watch Faces
The companion app typically offers dozens of watch face designs, from minimalist digital clocks to feature-rich layouts showing weather, steps, heart rate, and battery level simultaneously. You can also set custom photos as watch faces on some CN6 variants, adding a personal touch.
Optimizing Battery Life
If you notice the CN6 square smartwatch battery draining faster than expected, try these adjustments:
- Disable the always-on display and set the screen timeout to 10 seconds
- Reduce the frequency of heart rate monitoring from continuous to every 10 minutes
- Turn off unnecessary app notifications in the companion settings
- Disable SpO2 tracking during the day if you only need it at night
- Lower the screen brightness manually instead of using auto-brightness
Firmware Updates and App Maintenance
Keeping the watch firmware and companion app up to date is crucial for stability and new feature additions. The app usually prompts you when an update is available. Always update while the watch is connected to Wi-Fi or has sufficient battery, as firmware flashing can drain power quickly and interrupted updates may cause issues.
Common Troubleshooting and Solutions
Issue: Watch will not pair with phone. — Delete the device from the app’s Bluetooth list, restart both the watch and phone, then attempt pairing again from scratch.
Issue: Heart rate readings seem inaccurate. — Ensure the strap is snug but not overly tight, and position the sensor about one finger width above the wrist bone. Cold temperatures can temporarily affect optical readings.
Issue: Notifications not appearing. — Check that notification permissions are granted for the companion app on your phone. On Android, go to Settings > Apps > Companion App > Notifications and enable all relevant categories.
Issue: Screen freezes or unresponsive. — Perform a soft reset by holding the side button for 10 to 15 seconds until the watch vibrates and restarts. This resolves the majority of minor software glitches.
Final Verdict and Recommendations
The CN6 square smartwatch delivers exceptional value for users seeking a reliable, feature-packed fitness wearable without the premium price tag. Its square design offers practical advantages for data readability, and the comprehensive health and fitness tracking suite covers the needs of most everyday users. While it may lack the app ecosystem and cellular connectivity of flagship smartwatches, these trade-offs are entirely reasonable given its affordable price point.
Our recommendation: If you are new to smartwatches or simply want a dependable second device for health tracking, the CN6 square smartwatch is an excellent starting point. Advanced users might consider pairing it with a premium watch for specific high-end features while relying on the CN6 for daily activity monitoring.
FAQs About the CN6 Square Smartwatch Guide
Can I swim with the CN6 square smartwatch?
Yes, the CN6 square smartwatch is rated at 5 ATM, meaning it is water-resistant up to 50 meters. You can safely wear it while swimming, showering, or engaging in water-based activities. However, it is advisable to rinse it with fresh water after exposure to chlorinated or saltwater pools to maintain long-term durability.
How accurate is the heart rate monitor on the CN6?
The optical heart rate sensor on the CN6 square smartwatch provides reliable readings during steady-state activities like walking and cycling. During high-intensity interval training or exercises involving rapid wrist movements, accuracy may decrease slightly. For clinical-grade precision, chest strap heart rate monitors remain the gold standard.
Is the CN6 square smartwatch compatible with iPhone?
Absolutely. The CN6 square smartwatch works with both Android and iOS devices through its companion Bluetooth app. While some third-party app integrations may be limited on iOS compared to Android, core features like notifications, heart rate tracking, and sleep monitoring function fully on both platforms.
How long does the CN6 battery last on a single charge?
With typical usage — including daily notifications, intermittent heart rate monitoring, and moderate workout tracking — the CN6 square smartwatch delivers approximately five to seven days on a single charge. Enabling the always-on display or frequent GPS usage may reduce this to three or four days.
Can I use the CN6 without a smartphone?
The CN6 square smartwatch requires an initial smartphone pairing for setup and firmware updates. However, once configured, it can function independently for a limited time, storing workout data and displaying notifications if previously synced. Full functionality, including real-time syncing and app control, requires the companion smartphone app.
