1. 1.85-Inch AMOLED Display

One of the biggest highlights of the ColorFit Pulse 4 is its 1.85-inch AMOLED HD display.

The screen has a 390 × 450-pixel resolution, giving the watch a sharp and colourful interface. The AMOLED panel is particularly useful for viewing notifications, watch faces, health information and other details directly on the wrist.

2. Bluetooth Calling

The ColorFit Pulse 4 supports Bluetooth calling, allowing you to handle calls from your wrist when the watch is connected to your smartphone.

The calling system includes features such as caller information, call rejection, recent calls and contact access.

Remember that it relies on a Bluetooth connection with your phone, so it is not a standalone cellular smartwatch. Noise's support information also notes that Bluetooth calling can switch off automatically after the watch has been disconnected from the phone for more than three minutes to save battery.

3. Bluetooth 5.3

The smartwatch uses Bluetooth 5.3 for connectivity with compatible smartphones.

This helps the watch communicate with your phone for calling, notifications, synchronization and other connected features.

4. 100+ Watch Faces

The Noise ColorFit Pulse 4 offers 100+ watch faces, giving users plenty of options to change the appearance of the smartwatch.

You can choose different designs depending on whether you want a traditional watch look, a sporty interface or something more colourful.

Watch-face options can be managed through the NoiseFit app.

5. Heart-Rate Monitoring

The watch includes a heart-rate sensor for monitoring heart rate during everyday use.

This can help you keep track of changes in your heart-rate readings throughout the day and during activities.

However, smartwatch health measurements should be treated as wellness information rather than medical measurements.

6. SpO2 Monitoring

The ColorFit Pulse 4 also includes an SpO2 sensor.

It can provide estimated blood-oxygen readings through the watch's sensor system.

For the most accurate results, the watch should be worn correctly and kept in proper contact with the skin. Noise also warns that factors such as movement, sweat and an improper fit can affect health readings.

7. Sleep Monitoring

Sleep tracking is another useful feature of the ColorFit Pulse 4.

The watch can monitor sleep-related information and provide insights through the NoiseFit ecosystem.

This can be useful if you want to understand your general sleeping patterns rather than simply tracking steps and workouts.

8. Stress Monitoring

The smartwatch includes stress monitoring to provide an estimate of your stress levels.

It is designed as a wellness feature and should not be considered a medical or psychological diagnostic tool.

9. Female Cycle Tracking

The ColorFit Pulse 4 also includes a female cycle tracking feature.

Users can record and monitor relevant cycle information through the smartwatch and connected app.

10. AI Voice Assistant

The smartwatch supports an AI voice assistant, allowing users to interact with voice-assistant functionality through the device.

This adds another hands-free option for everyday smartwatch tasks.

11. Useful Everyday Smart Features

The Pulse 4 isn't only focused on health tracking. It also includes several practical features for everyday use.

These include:

• Caller name information
• Call rejection
• Stopwatch
• Timer
• Alarm
• Reminders
• Weather information
• Music controls
• Calculator
• Vibration alerts
• Do Not Disturb mode
• Screen brightness control
• Wrist-awake function
• Functional crown

These small features can make the smartwatch more convenient for daily use.

12. Functional Crown

The functional crown makes navigating the watch interface easier.

Instead of relying entirely on touchscreen controls, the crown provides another way to interact with the interface and navigate through menus.

This can be particularly convenient when scrolling through different options.

13. IP68 Water Resistance

The ColorFit Pulse 4 carries an IP68 rating, providing protection against dust and water exposure under supported conditions.

However, an IP rating does not mean every type of water exposure is suitable. Users should follow Noise's usage recommendations rather than treating the watch as suitable for every swimming or water-based activity.

14. Up to 7 Days of Battery Life

Noise rates the ColorFit Pulse 4 for up to 7 days of typical usage and up to 30 days of standby time.

The watch takes up to around 2 hours to charge.

Actual battery life can vary depending on factors such as screen usage, brightness, automatic health monitoring, notifications and Bluetooth calling.

15. NoiseFit App

The ColorFit Pulse 4 works with the NoiseFit app, which provides a central place to manage the smartwatch.

The app can be used for functions such as:

• Watch setup
• Watch-face management
• Health-data synchronization
• Device settings
• Software updates
• Other smartwatch preferences

Noise's support page recommends connecting the watch through the NoiseFit app when checking for software updates.

16. Smartphone Compatibility

The ColorFit Pulse 4 is designed to work with both Android and iOS smartphones.

A smartphone connection is required for connected features such as Bluetooth calling, synchronization and app-based functions.
