Frequently Asked Questions
Is 5ATM better than IP68 for swimming?
5ATM (50m) is generally clearer for swim use — it’s designed to withstand pool laps and swimming. IP68 covers dust and water immersion but implementations vary; always check the product notes to confirm if the model is tested for lap swimming and avoid hot showers and diving unless explicitly rated.
How tightly should I wear a tracker for accurate heart-rate and swim data?
Wear the tracker snugly but comfortably; it should sit stable on the wrist without rotating. Many manufacturers recommend a slightly tighter fit during workouts and sleep a bit looser overnight. A stable fit reduces motion artifacts and improves optical sensor accuracy.
Can these trackers replace a medical device for blood pressure or SpO2?
No — consumer trackers provide helpful trend data but are not medical-grade. Use readings for fitness and wellness tracking, and consult healthcare professionals for clinical measurements or diagnosis.
