Frequently Asked Questions
Apple Watch vs Garmin for fitness: which is better?
Garmin wins for serious fitness: longer battery life (7-14 days vs 1-2 days), more detailed training metrics, and superior GPS accuracy. Apple Watch wins for everyday smartwatch features: apps, notifications, Apple ecosystem integration, and casual fitness tracking. Choose Garmin if fitness is the priority; Apple Watch if you want a do-it-all smartwatch.
How accurate are smartwatch heart rate sensors?
Modern optical heart rate sensors are 95-99% accurate at rest and 90-95% accurate during steady-state exercise. Accuracy drops during high-intensity intervals and wrist-intensive exercises (like rowing or kettlebells). For maximum accuracy during intense training, pair your watch with a chest strap heart rate monitor.
Do I need cellular connectivity on a fitness watch?
Only if you want to receive calls, texts, and stream music during workouts without your phone. GPS tracking works without cellular. Most runners and cyclists leave their phone behind — cellular lets you stay reachable in emergencies. It adds $5-10/month to your phone plan. For gym-only use, cellular is unnecessary.
