Best fitness tracker: The most important features
1. sensors and their importance
Modern fitness trackers have a variety of sensors that collect data about your activities and health. You should keep an eye on the following sensors:
Heart rate monitor
A heart rate monitor is standard on almost all fitness trackers. It measures your heart rate in real time and provides important information for your training, such as the optimum heart rate zone. Make sure that the sensor is precise and can measure continuously.
SpO2 sensor (oxygen saturation)
An SpO2 sensor measures the oxygen content in the blood. This function is particularly important for athletes who train at high altitudes or for monitoring sleep apnea.
Accelerometer and gyroscope
These sensors are responsible for motion detection. They record your steps, the distance covered and movement patterns. A precise algorithm that does not count incorrect movements such as hand gestures as steps is particularly important.
GPS
An integrated GPS module makes it possible to record your routes without a smartphone. This is ideal for joggers, cyclists or hikers. Alternatively, some trackers offer “Connected GPS”, which relies on a connection with your smartphone.
Skin temperature and stress sensors
These sensors are more commonly found in high-end models and offer advanced ways to monitor your wellbeing.
2. compatibility with smartphones
A fitness tracker usually relies on a connection with an app. Check whether the device is compatible with both Android and iOS devices. Some trackers offer limited functionality on one of the two operating systems. Make sure that the app is clearly laid out and provides detailed reports.
3. battery life
Battery life varies greatly between models. While simple trackers can last up to two weeks, models with GPS or AMOLED displays often need to be recharged after just a few days.
Tips on battery life
- Trackers with an “always-on display” consume more energy.
- GPS should only be switched on when required.
- Models with efficient energy management offer more flexibility.
4. Display and operation
The display is one of the most important elements of a fitness tracker, as it presents the data visually. Pay attention to the following aspects:
Display types
- AMOLED or OLED: Brilliant colors and high contrast, but higher energy consumption.
- LCD: Energy-saving, but often less bright.
- E-Ink: Ideal for long battery life, but limited color display.
Touchscreen vs. buttons
A touchscreen is intuitive, while physical buttons work better in wet or cold environments.
5. waterproofness
Almost all fitness trackers today are at least splash-proof. If you want to swim or do water sports, the device should have a water resistance of at least 5 ATM.
6. design and wearing comfort
The design of a fitness tracker not only influences its aesthetics, but also its wearing comfort. Flexible and skin-friendly materials as well as a low weight ensure that it is comfortable to wear, especially during longer sessions.
Best fitness tracker: Functions of fitness trackers
1. sleep tracking
Many fitness trackers offer sleep monitoring. Precise trackers can recognize sleep phases such as light, deep and REM sleep. This function is particularly interesting for you if you want to improve the quality of your sleep.
2. fitness coaching
Some models offer personalized workouts and real-time coaching. These functions are particularly helpful for beginners or users who are pursuing specific training goals.
3. music control and smartphone notifications
Practical additional functions such as controlling music and receiving notifications make fitness trackers a multifunctional gadget.
4. payment functions
High-end models offer NFC for contactless payment. This is particularly practical when you are out and about without a wallet.
5. altimeter and floor counter
There are fitness trackers that offer both an altimeter and a floor counter. Some models use a barometer to measure differences in altitude and thus determine the number of floors climbed.
6. stress management and breathing exercises
In our fast-paced world, stress is increasingly becoming a serious health risk. Not only mental, but also physical illnesses can result. Some fitness trackers offer comprehensive stress management with breathing exercises and recommended breaks.
7. breathing monitoring
Some fitness trackers offer comprehensive breathing rate monitoring. This can improve respiratory health, which is particularly important for people with chronic respiratory diseases.
8. internal memory for music storage
Especially people with large smartphones rarely want to carry the extra weight of a cell phone with them when running. But how can you enjoy your favorite music then? This is where the internal memory of the tracker comes into play. After all, many models offer enough storage space to listen to your favorite music and podcasts even without a smartphone.
9. inactivity alarm
You snooze, you lose. In our unfortunately often sedentary everyday lives, it’s not so easy to always be mobile and not remain stoically in your desk chair all day. The helpful inactivity alarm on many fitness trackers notifies the wearer when they need to stretch their legs again.
Best fitness tracker: consider the running costs
When you buy a fitness tracker, you usually haven’t paid off the total cost of the health gadget. If you want to get the full potential out of the wearable, you also need to keep running costs in mind. In addition to the regular replacement of wristbands, which is particularly important if you use them frequently for sport, you may also have to factor in subscription costs. Some manufacturers charge for the helpful app service as part of a subscription model.
Examples of subscription models:
- Fitbit Premium (€ 8.99 per month / € 79.99 per year)
- Whoop (€ 30 per month / € 264 per year / € 444 per year)
