Buying a Fitness Tracker 2025: What Really Matters?
GPS, heart rate, sleep – which fitness tracker suits you? We explain the key differences clearly and simply.
The market is full of fitness trackers between €20 and €300. Which one is right? Depends entirely on what you want to do with it.
1. Just a Step Counter or More?
Cheap models under €30 count steps and measure sleep – that's it. From €50, heart rate monitoring and sports modes are added. For serious training analysis you need at least €80–100.
2. Do I Need GPS?
GPS is handy for running without a phone. But: GPS drains the battery. A tracker with built-in GPS often lasts only 5–8 hours in GPS mode. If you always run with your phone anyway, "connected GPS" is enough.
3. Heart Rate Measurement: Wrist vs. Chest Strap
Most trackers measure at the wrist – convenient, but less accurate. For interval training or medical accuracy, a chest strap is better. Many trackers can pair with a chest strap.
4. Sleep Tracking – How Good Is It Really?
Cheap trackers only recognize "slept / not slept". More expensive models recognize deep sleep, REM, and light sleep. For real sleep optimization, the investment is worthwhile.
5. Battery Life
The more features, the shorter the battery. A simple tracker runs 7–14 days. With always-on display and GPS: 1–3 days. Consider how often you want to charge.
