Frequently Asked Questions
How accurate are fitness tracker step counts?
Premium trackers (Fitbit, Garmin, Apple Watch) show ±10% error on step counts — acceptable for most use cases. Budget trackers can err by 20-30%. For medical-grade accuracy, clinical-grade devices are required. Step counts are best used for relative trends, not absolute measurement.
Are fitness trackers accurate for calorie counting?
No — calorie estimates from wrist trackers show 15-43% error in studies. Use them as relative indicators, not precise measurements. Heart rate-based calorie estimates are significantly more accurate than motion-only estimates.
How long do fitness tracker batteries last?
Entry level: 1-3 days (Apple Watch). Mid-range: 7-14 days (Fitbit Charge, Garmin Vivosmart). GPS trackers: 7-18 days battery mode, 5-20 hours GPS-on. Consider your charging habits — a tracker that runs out mid-day provides no data.
Can fitness trackers detect health problems?
Select trackers can detect: atrial fibrillation (Fitbit, Apple Watch — FDA-cleared ECG), irregular heart rhythms, and significant low heart rate. They are screening tools, not diagnostic devices. Always consult a physician for health concerns regardless of tracker data.
Should I wear my fitness tracker 24/7?
Wearing during sleep adds valuable data (sleep stages, resting heart rate, recovery metrics) and is generally safe. Give your wrist 1-2 hours of air daily to prevent skin irritation. Remove during contact sports, heavy lifting, or water sports beyond the tracker’s water resistance rating.
