Standard Edition Special Edition

An activity meter with a built-in activity meter that can record steps, distance, calories burned, number of stairs climbed, stages of sleep, etc. In addition to GPS and waterproof function to a depth of 50m, it has a heart rate sensor.

Even though it has a display with a touchscreen, it has a battery life of up to 7 days. Even if you use GPS continuously, you can use it for up to 5 hours.

It can also work with smartphones to display incoming calls, calendar appointments, text message reception, and app notifications. If it is an Android device, it has a "quick reply function" that allows you to reply to text messages from this unit.

By installing GPS, it is now possible to measure walking speed and distance in real time. In addition, after a workout, you can check the workout intensity for each heart rate zone along the route you followed with the dedicated app, and visualize what kind of performance you showed on various terrains.

After a workout, you can use the dedicated app to check the workout intensity for each heart rate zone along the route you followed. Suppose we track not only the number of steps taken, but also physical activity, and improve health along with the effects of daily activity.

For example, you get points every minute for moderate activity in the fat burn zone, and double points for high intensity activity in the cardio and peak zones. That way, Active Zone Minutes automatically calculates how many more activities you need to do to reach your daily or weekly goal.

Sleep-related functions are also enhanced. Equipped with "Smart Wake" that wakes up the user at the most appropriate time by machine learning. It also has an alarm and sleep mode.

In addition, the combination of the red sensor and infrared sensor installed on the back estimates changes in blood oxygen concentration. Short-term fluctuations in blood oxygen levels may indicate changes in breathing during sleep.
