Apple Watch Ultra 4 vs Samsung Galaxy Watch Ultra 2
This is really a phone decision, since the Ultra 4 only works with iPhone and the Ultra 2 only works with Android. On paper the Ultra 4 has the edge for runners, with real offline maps and Apple's max analytics tier, while the Ultra 2 costs $100 less, adds 2 more hours of GPS, and has a much brighter 5,000-nit display. Neither has an established rating yet.

- •You're on iPhone, so this is your only Ultra
- •You want real offline maps and the deeper analytics tier
- •You're on Android, so this is the only Ultra that pairs with your phone
- •You'd rather keep $100 and get more GPS runtime and a brighter screen
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 2 keeps the titanium case and dual-frequency GPS, then adds a much bigger battery in a thinner 10.7mm body, a 5,000-nit display, and EN13319 dive certification to 40 meters. A Trail Run mode with climb guidance and GPX turn-by-turn routes make it a real running tool, though it follows loaded routes instead of showing full offline maps. It's Android-only, sold in one 47mm LTE-ready size, and at $699.99 it undercuts the Apple Watch Ultra 4 by $100.
