AMOLED, or Active Matrix Organic Light-Emitting Diode, belongs to the OLED family of display technologies. This is the most advanced display technology on the market. Compared with competing technologies, it boasts faster response times, lower energy consumption, and sharper colours. You can also enjoy perfect black colour reproduction, which results in better readability in direct sunlight. AMOLED displays also offer wide viewing angles, which in the case of IPS displays reach almost 180 degrees. However, the disadvantage of AMOLED technology is its higher price and shorter lifespan.

A barometer is a sensor in a smartwatch that measures atmospheric pressure. It is used for weather forecasting, determining altitude and assisting in navigation. Its ability to provide data on pressure changes is crucial for outdoor activities such as hiking or climbing, where it can help in making safe decisions.

Galileo is Europe's global satellite navigation system that provides precise position and time information. The integration of Galileo into smartwatches improves location accuracy, which is advantageous for applications requiring accurate geolocation data such as maps, fitness and outdoor activity tracking.

Glonass is a Russian global navigation satellite system that works in parallel with the US GPS system. The use of Glonass in smartwatches is particularly advantageous for outdoor activities such as running, hiking, cycling or any other activity where tracking route, speed and distance traveled with a high level of accuracy is important.

An accelerometer is a sensor that measures and monitors changes in the speed of motion. In smartwatches, it is used to track physical activity such as step count, running, cycling and to recognize different types of movement. This sensor is the basis for fitness and health applications.

The heart rate zones are divided by percentage of maximum heart rate and are used to monitor exercise intensity. Using these zones, smartwatch users can optimize their training to burn fat, improve endurance or maximize performance. Heart rate zones allow you to train more efficiently and reach your fitness goals with greater precision.

Integration with the Strava app allows smartwatch users to sync and share their sports activities with the Strava community. This feature offers access to the app's extensive analytics tools, segments and social features, motivating users to improve performance and track progress within the athlete community.

Inteligentné hodinky toho dnes dokážu naozaj veľa a navigácia nie je výnimkou. Niektoré hodinky možno použiť len na zobrazovanie pokynov na trase naplánovanej v telefóne. Iné však umožňujú priame vyhľadávanie a niektoré majú dokonca mapové podklady priamo vo vlastnej pamäti. Ako navigácia v inteligentných hodinkách funguje?

Always On Display allows the smartwatch display to be constantly active and display basic information such as time, date or notifications without the need to activate the display with a button or wrist movement. This feature adds to the convenience of using the watch, but may affect battery consumption.
