Design
The size of the screen (measured diagonally).
The type of technology used in the display.
The device is dustproof and water-resistant. Water-resistant devices can resist the penetration of water, such as powerful water jets, but not being submerged into water.
Ingress Protection (IP) rating
Unknown. Help us by suggesting a value. (Xiaomi Mi Band 4)
Unknown. Help us by suggesting a value. (Xiaomi Smart Band 7)
The first number of the IP rating refers to protection against dust, while the second number refers to protection against liquid. E.g. a first number of 6 denotes that it is completely dustproof, and a second number of 7 denotes that the device can withstand full immersion in water.
The ATM rating indicates how much water pressure a device can withstand. 3 ATM is one of the lowest ratings and means that the device can only withstand splashes of water, whereas 20 ATM is one of the highest ratings and means that the device can be used for snorkeling and water sports.
Pixel density is a measurement of a screen's resolution, expressed as the number of pixels per inch (PPI) on the screen. A higher pixel density translates into more clarity and sharpness for the images rendered on the screen, thus improving the quality of the viewing experience.
Resolution is an essential indicator of a screen's image quality, representing the maximum amount of pixels that can be shown on the screen. The resolution is given as a compound value, comprised of horizontal and vertical pixels.
Damage-resistant glass (such as Corning Gorilla Glass or Asahi Dragontrail Glass) is thin, lightweight, and can withstand high levels of force.

Gorilla Glass is one of the most popular brands of chemically strengthened glass, manufactured by Corning. Several versions have been developed, the newer ones being more durable and providing better damage resistance.
Sensors
GPS enables global positioning, useful in map, geo-tagging or navigation apps.
A heart rate monitor can help show your fitness levels, enabling you to calculate a suitable intensity of exercise.
Your blood oxygen level is a measurement how much oxygen is reaching your muscles. It is important because low levels mean that you will become easily fatigued during exercise. The more exercise you do, the better your blood oxygen levels will become.
ECG stands for electrocardiogram and measures the electrical activity of the heartbeat, which is a more in-depth reading of heart health than blood pressure alone. Note: This feature may not be available in all markets.
With a temperature sensor you can monitor changes in temperature to measure your exertion levels and avoid hyperthermia.
This measures barometric air pressure. It can predict weather changes, for example a sudden drop in air pressure could mean a storm is coming. When calibrated correctly it can be used to determine altitude, which helps GPS devices to lock on quicker and with greater accuracy.
A gyroscope is a sensor that tracks the orientation of a device, more specifically by measuring the angular rotational velocity. Initially, they were built using a spinning rotor to detect changes in orientation, like twisting or rotation.
A cadence sensor measures the number of pedal revolutions per minute when you are cycling. It enables you to monitor how fast you are pedaling.
The device can measure the level of perspiration on your skin, indicating the level of intensity of your workouts.
Activity tracking
The device automatically detects when you start an activity such as jogging, saving you from entering it manually at a later time.
A multi-sport mode allows you to easily switch between tracking different sports such as running, cycling, and swimming. This feature is ideal for those who need to change quickly between various activities (e.g., triathletes).
After exercising, you can add details about your workout (e.g., jogging, swimming, cycling). This enables the device to provide more accurate information, such as the number of calories burned.
It can detect changes in elevation, such as when you are climbing stairs.
It tracks how far you travel.
It tracks how many steps you take throughout the day, allowing you to see how active you have been.
With a route tracker you can add your route onto a map. It is helpful if you plan to do the same route again, or want to share it with your community.

It is compatible with a range of Android devices such as smartphones and tablets.
It is compatible with a range of iOS devices such as iPhones, iPads and the iPod Touch.
Galileo is a global navigation satellite system (GNSS) that is similar to GPS. Supported devices can use a combination of Galileo and GPS for location-based services such as Google Maps, and tend to be around 30% more accurate than GPS-only devices.
