Your Life, Your Sport
Are you looking for a healthy and sporty lifestyle? The iD.LIFE combines the most important functions of a sports watch with an activity tracker and without any smart phone app. It remains simple in operation and fascinates with a clearly structured menu.
You can get all relevant workout values including personal target zones via the heart rate measurement on the wrist, while the activity tracker provides the additional portion of fitness that lies beyond all sporting activities. This makes the iD.LIFE your indispensable workout partner and everyday companion.
Wrist-Based Heart Rate
The heart rate measurement on the wrist is performed by means of an optical sensor, which makes a chest strap obsolete. The heart rate is recorded continuously during a training interval.
Your heart rate is displayed on the start screen via the activity tracker even when you are not working out.
Your fitness coach
Based on your heart rate, the iD.LIFE shows you in which workout area (for example, cardio, fitness, performance) you are currently in. If you have defined a target heart rate, you can use the graphical zone indicator to determine the relation of your current heart rate to the set zone. The iD.LIFE gives you additional feedback via a vibration alarm when it exceeds or falls short of the target zone.
The principle of heart rate measurement on the wrist is simple:
Light is irradiated onto the skin and an optical sensor measures the reflection of the light. How much light is reflected is influenced, among other things, by how much blood passes through the illuminated spot. The blood flow changes during the beat of the heart. The heart rate is recorded in this way.
The iD.LIFE gives discreet feedback via the vibration alarm, for example, if a day's target has been achieved and it also helps to monitor the target heart rate better.
This is an important feature particularly in a noisy environment.
The iD.LIFE uses a 3D accelerometer. By recognising the striking patterns of movement, steps can be detected and recorded.
The distance is measured using this motion sensor. To adjust the measurement accuracy to your own running style, you can calibrate the iD.LIFE, for example, on the track at a stadium.
