I walked 10,000 steps with the Apple Watch Ultra 4 vs Garmin Fenix 9 Pro — and I was not expecting this
Tom's Guide conducted a comparative test of the Apple Watch Ultra 4 and the Garmin Fenix 9 Pro by manually counting 10,000 steps to evaluate their pedometer accuracy. The test aimed to determine which high-end adventure watch performs better at tracking basic movement metrics using internal accelerometers. The article highlights the specific features and pricing of both devices while detailing the methodology used to measure their step-counting capabilities.
- ▪The Apple Watch Ultra 4 is priced at $799 and features an improved heart rate monitor with 50 hours of battery life.
- ▪The Garmin Fenix 9 Pro costs $1,099 and includes a built-in flashlight along with extended battery life.
- ▪Both devices utilize internal accelerometers to count steps by measuring arm swing, with each swing registering as two steps.
- ▪The tester wore the Apple Watch on the left wrist and the Garmin on the right while using a manual clicker to verify the exact step count.
