What reviewers say
Distilled from the video reviewers — the score, what they praise, where they push back.?
Reviewers praise
- Battery lasts three to six days with quick charging
- Physical button replaces the unreliable capacitive touch sensor from the original
- AMOLED display delivers vibrant colors and remains readable in sunlight
Reviewers push back
- Many health features require a Fitbit Premium subscription to access in-depth metrics
- Runs Fitbit OS instead of Wear OS, limiting app selection and smart features
- GPS tracking can be inaccurate, sometimes registering five percent error and phantom paths
“if this watch was running the wear OS you could have just kissed goodbye that kind of battery life”
Reviewers praise
- Exceptionally bright 3000-nit display excels in outdoor conditions and powers impressive flashlight functionality
- Double-tap gesture works reliably and becomes genuinely useful once adopted, especially for music and call control
- Excellent battery life delivers 36 hours of normal use, 72 hours with low-power mode
Reviewers push back
- Visually indistinguishable from the original Ultra, making the upgrade feel pointless for existing owners
- Action button is underutilized—reviewers consistently forget it exists or rarely press it
- Blood oxygen sensing removed on newer units due to legal issues, though hardware may still be present
The Ultra 2 is a minimal spec bump over the original Ultra, distinguished mainly by brighter display and double-tap gesture, making it worthwhile only for first-time buyers or those with very old watches.
