Apple Watch Ultra 4 vs Samsung Galaxy Watch Ultra (2025)
Both are each platform's rugged-smartwatch flagship, but the Ultra 4 now reaches Apple's max analytics tier for the first time, not just training-tier data, while the Galaxy Watch Ultra stays $150 cheaper and already has a track record of real reviews behind it.

- •You're on iPhone, so this is the only Ultra you can actually use
- •You want Apple's newly-added max-tier analytics and don't mind buying before reviews exist
- •You're on Android, so this is the only Ultra that pairs with your phone
- •You want rugged titanium durability for $150 less, backed by an established rating
The Ultra 4 keeps the titanium case and Action button of past Ultras, then pushes the display to 3,000 nits, dual-frequency GPS, and genuine offline maps with custom route creation. Training Load, VO2 max, running power, and satellite-based Emergency SOS round out a watch built as much for serious training as for the backcountry. It's still an iPhone-only watch, so it's not a fit if you're on Android, but for iOS runners who want real training data without leaving Apple's ecosystem, this is as good as Apple gets.
The Galaxy Watch Ultra pairs a rugged titanium case with genuinely long battery life for a Samsung device. It's the clear pick for Android users who want an outdoor-ready smartwatch without switching to Garmin or Coros.
*Estimated — this model's exact GPS battery life isn't published by the manufacturer. All figures are standard GPS mode, midsize case, no solar boost.
†Estimated — this model launched too recently to have an established customer rating yet.
