Apple Watch Ultra 2 Review: 2 Years Later, Still On My Wrist Every Day

I've been running since I was 13, and in that time I've cycled through a lot of gear. Garmins, Fitbits, more Apple Watches than I'd like to admit. Two years ago I picked up the Apple Watch Ultra 2, and it's the one that stuck. It's been on my wrist through hundreds of runs, a couple thousand nights of sleep, and everything in between. So this isn't a first-impressions review off a spec sheet. This is what I actually think after living with it for two years.

Short version: for a runner who cares about their health, it's still the best all-around watch I've owned. Here's the long version.

It Started as a Running Watch and Became a Health Tool

When I bought it, I was thinking about runs. Pace, distance, heart rate zones, GPS accuracy. And on that front the Ultra 2 delivers. The GPS is the most accurate I've used in a sports watch, so my splits and routes actually match reality instead of drawing me swimming through buildings. I mostly live in the built-in Workout app, but I've bounced around to Nike Run Club and a few others over the years, and they all run smoothly.

What I didn't expect two years ago is how much I'd end up using it as a health device instead of just a fitness one. That shift is the real story of owning this watch long-term.

The Sleep Apnea Feature Changed How I Use It

This is the big one for me, and it's a feature that didn't even exist when I first bought the watch. I've suspected for a while that I might have sleep apnea, and after a software update the Ultra 2 added sleep apnea notifications. It watches for a metric Apple calls breathing disturbances — small movements at your wrist tied to interruptions in your breathing overnight — and flags patterns that could point to moderate to severe sleep apnea.

To be clear, it's not a diagnosis and it doesn't replace a doctor. But as someone who's been quietly worried about this, having the watch track my breathing disturbances night after night gives me real data instead of just a hunch. It turned the watch from "thing that counts my runs" into "thing that's actively looking out for my health while I sleep." That's a big deal, and it's the kind of update that makes me glad I stayed in the Apple ecosystem.

The Vitals App Is Quietly One of the Best Additions

Another feature that showed up after launch: the Vitals app. Overnight it tracks your heart rate, respiratory rate, wrist temperature, sleep duration, and blood oxygen, then tells you when any of them drift outside your normal range.

If you've read anything I've written about recovery — like my guide to heart rate variability — you know I'm a big believer that the numbers your body gives you overnight are more honest than how you feel when the alarm goes off. Vitals leans right into that. When two or three of my metrics are off on the same night, that's usually my body warning me I'm run down or something's coming on. It's the same early-warning idea I love about tracking recovery, built right into the watch.

Runs, Recovery, and Training Load

The other post-launch addition worth calling out is training load. After a workout the watch asks how hard it felt, then builds that into a running picture of whether you're ramping up too fast or coasting. For a runner, that's the difference between building fitness and building an injury. After 12 years of running, the lesson that took me longest to learn is that you get faster from the workouts you recover from, not the ones you grind through — it's the whole reason I keep most of my miles easy and aerobic. Having that context on my wrist keeps me honest on the days my ego wants to push.

Between the workout tracking, training load, and the overnight health data, the Ultra 2 covers both halves of training: the hard work, and whether your body is actually absorbing it.

Living With It Day to Day

Two years in, the watch still looks great. The titanium case has shrugged off bumps, drops, and plenty of accidental door frames without any real damage. I've got a smaller wrist and worried the 49mm case would feel like a hockey puck, but with the right band it sits snug and I stop noticing it.

The always-on display is one of those small things that turns out to matter every day. Older watches made you flick your wrist to wake the screen, which is annoying mid-run when your hands are busy. The Ultra keeps the screen on at a dimmer setting, so a quick glance is all I need. And it's bright — easy to read in direct summer sun, which for an outdoor runner is not a small thing.

The Action Button has earned its spot too. I've got mine set to start a run instantly, so I'm not tapping through menus at the start line with cold fingers.

The Downside: Battery and Sleep Tracking

I'll give it the same critique I had two years ago, because it's the one thing that hasn't fully gone away. Battery life is good — up to about 36 hours of normal use, more in Low Power Mode — and it fast-charges to 80% in roughly an hour. For a smartwatch that does this much, that's solid.

But if you want to track your sleep every night, you have to find a window to charge it, and that's a real puzzle. It's the one spot where a device you never take off would be better. My workaround is topping it off while I shower or eat breakfast, so it's ready for bed. It works, but it takes a little planning, and I'd love to see future versions stretch the battery far enough to make charging an afterthought.

This is also why I ended up wearing an Oura Ring 4 for overnight tracking alongside the watch — the ring handles sleep without ever needing to come off, and the watch handles everything else. If you're serious about sleep data, that combo is worth thinking about.

The Little Things That Add Up

A few things that don't need their own section but make daily life easier:

• Water resistance to 100 meters means I never think twice about rain, sweat, or jumping in a pool. It's swim-proof and then some.
• The ecosystem stuff just works. Calls, texts, music, podcasts, controlling my lights, leaving my phone at home on a run and still being reachable. None of it is flashy, but all of it removes small friction from the day.
• ECG and blood oxygen are there if you want a quick heart-rhythm check. They're wellness features, not medical devices, but it's reassuring to have them a tap away.

Who Should Actually Buy This

If you're an iPhone user who runs, hikes, swims, or just wants a watch that takes your health seriously, the Ultra 2 is an easy recommendation. The health features that arrived after launch — sleep apnea notifications, Vitals, training load — have made a two-year-old watch feel newer than when I bought it, which almost never happens with tech.

If you never track sleep and just want the basics, you can save money with a standard Series watch. And if your main goal is uninterrupted overnight tracking, pair it with something you don't have to charge, or look at a smart ring.

Two Years In: Would I Buy It Again?

Yeah, without hesitation. The Ultra 2 stopped being a gadget for me and became part of how I take care of myself. It tells me how my runs went, whether I've recovered enough to push, and — the part I never saw coming — it's actively watching my breathing at night for signs of something I've worried about for years.

For a runner who cares about being the healthiest version of themselves, that's exactly what you want from the thing on your wrist. The battery still nags me a little. Everything else has more than earned its place.
