The best smartwatch to pair with an iPhone in 2025 remains the Apple Watch in all its forms. It's worth noting that new models are incoming, so this guide will soon be updated once we have time to review those models in full. However, until then, we're using the current crop of watches: the Apple Watch Series 10, SE (2022) and Apple Watch Ultra 2.
However, these are far from your only choices. You could opt for a cheaper option from Huawei or Amazfit, or a specialist sport model such as the Garmin Venu X1. Garmin has its own suite of advanced fitness metrics, and you could check out our best Garmin watch guide for more options as they're entirely system-agnostic. All you need is the free Garmin Connect app on your phone.
We tend to recommend Apple's own offerings for pairing a smartwatch with an iPhone, as they enjoy unprecedented synergy with the iPhone that you won't get from any other vendor, with features like iPhone Focus Modes reserved for Apple Watch functionality. While Apple Watches aren't the only smartwatches you can pair with an iPhone, they definitely offer the best experience.
We rate every model for design, features, performance, and, of course, value, giving each model a score out of five and an overall score. We collate that data to bring you these recommendations, and you won't find any models on the market that we haven't tested.
So no matter your budget, here are the best smartwatches for iPhone in 2025.

Best overall
The Apple Watch Series 10 is the best overall pick for iPhone users, even though the Ultra 2 is technically more performant. It comes with a brighter OLED display compared to previous generations, and Apple's most advanced chip.
Best cheap Apple Watch
A solid balance of affordability and performance. The SE 2 is a stripped-back Apple Watch that’s missing some features. But it has everything most people could need – especially those on a tight budget.
Best premium
A rugged, premium smartwatch for lovers of the great outdoors or those who want Apple’s best tech on their wrists. If you love fitness, especially outdoor activities, this is the best option for you.
Best Garmin
Apple isn’t the only brand that makes excellent watches for the iPhone. The Venu X1 is our top Garmin pick with a bold, bright display and fantastic health and fitness tracking that balances functionality with value.
Best cheap
The best cheap smartwatch you can buy that works with an iPhone is the Amazfit Active 2. It's got amazing battery life, loads of health and fitness features, and a classic design.
Best Huawei
This is the best smartwatch for iPhone users who want a Huawei device. Well worth considering if you'd like a snappy smartwatch packed with features. But it does have a couple of frustrating pain points that might be a dealbreaker for some.
The best smartwatch for iPhone overall
If you’re looking for a new smartwatch for your iPhone, there are plenty of Apple Watch choices. There’s the cheap Apple Watch SE 2 or premium, outdoorsy Apple Watch Ultra 2 options further down in this guide. But if you want a balance of features and value, our top pick for most people is the Apple Watch Series 10.
The Apple Watch Series 10 retains the signature Apple Watch design of previous models, including a sleek, rounded square case with a vibrant, responsive touchscreen. It's available in aluminum or stainless steel finishes, with 42mm and 46mm case sizes (slightly bigger than its predecessor, which offered 41mm and 45mm respectively), and features the familiar rotating crown and side button. One of the key updates is a brighter display, making it more readable in direct sunlight from all angles thanks to its larger, curved "wide-angle OLED" screen. The Series 10, like the Series 9 before it, comes with Apple's carbon neutral rating.
The S10 chip follows on from the S9, another standout upgrade delivering improved performance, faster Siri processing, and 64GB memory capacity. Last year's Double Tap feature is here, and health tracking remains a top priority, with features like blood oxygen monitoring, ECG, and temperature sensing, The Series 10 also offers Sleep Apnoea detection, with watchOS 11 offering a new Vitals app for sleep tracking. Unfortunately, even though it charges to 80% in 30 minutes, the watch only lasts for 18 hours in smartwatch mode, so daily charging is required.

The best cheap Apple Watch for iPhone
The Apple Watch SE 2 is an excellent choice for iPhone users who want a budget-friendly smartwatch. Released in 2022, the SE 2 has the signature Apple Watch design with a lightweight aluminum case and a vibrant OLED display, though it lacks the always-on screen you’ll find in more expensive models. Available in 40mm and 44mm sizes, it’s comfortable for all-day wear and delivers a smooth performance with Apple’s S8 chip onboard.
While you won’t find premium features on the SE 2, like ECG or blood oxygen monitoring, it covers essential fitness tracking, including heart rate monitoring, GPS, sleep tracking, and Apple’s fall detection feature. The battery life is also strong, lasting around two days in typical use during our testing, which significantly outperforms Apple’s 18-hour estimate. This makes it ideal for everyday wear without constant recharging – a bugbear with the higher-priced and higher-specced Apple watches.
Though it lacks some of the extras of other Apple Watch models, the SE 2 offers fantastic value for those wanting a reliable smartwatch experience at a lower price point. In our Apple Watch SE 2 review, we wrote: “the Watch SE does 99% of what more expensive options do, just as quickly, just as smoothly.” It’s a solid balance of affordability and performance, making it one of the most tempting options for iPhone users looking for a more budget-friendly wearable that’s still distinctly Apple through and through.

The best premium smartwatch for iPhone
The Apple Watch Ultra 2, released in 2023, is a rugged smartwatch that's our top premium pick. Built with a durable titanium case, it boasts advanced GPS, dive-ready features, and a 36-hour battery, making it perfect for adventurers.
Its standout feature is the 3,000-nit display – the brightest on any Apple Watch se've tested. In our Apple Watch Ultra 2 review, we wrote: “It’s probably the best smartwatch screen I’ve ever seen in person from a purely technical standpoint.” The Ultra 2 is powered by the S9 chip, enabling the innovative Double Tap gesture for hands-free control of key functions, like answering calls and starting workouts.
While the upgrades from the original Ultra are modest, the eco-friendly materials, improved performance, and outdoor-focused tools make it one of the best premium smartwatches available. However, anyone with the original Ultra may not find enough new features to justify upgrading, and the battery life remains limited to around two days – not ideal for longer expeditions without charging.
For those who need durability and top-tier performance – especially in extreme environments – the Ultra 2 is a top choice. However, casual users might prefer the more affordable standard Apple Watch models.

The best Garmin smartwatch for iPhone
Apple isn’t the only brand to consider when picking the best smartwatch for iPhone. Garmin has consistently been one of the best fitness tech brands and, depending on your preferences, Garmin’s top smartwatches might better suit you. Our top Garmin pick right now is the Garmin Venu X1.
It’s an impressive fitness-focused smartwatch with a sleek design and an upgraded AMOLED display we thought was stunning during testing. In our review, we particularly loved its maps capability, which (unlike Apple) can be interacted with within the workout app itself – no switching apps on long runs, walks or cycles!
Its slender case and cambered stainless-steel back is light at just 34g, making it comfortable for all-day and all-night wear, whether you're working out or tracking daily activities. Without always-on display enabled, the Venu X1 lasts up to 9 days – realistically, a week with multiple GPS workouts. Features like Pulse OX monitoring, Body Battery and Training Readiness energy tracking, sleep tracking, Garmin Coach training plans and stress monitoring round things out. It's even got an LED torch!
It's not cheap, but for those who want a versatile and well-rounded fitness watch with excellent battery life while retaining that Apple Watch visual language, it’s a great option.

The best cheap smartwatch for iPhone
In 10 years of using Apple Watch, the $99 Amazfit Active 2 is the closest I've ever come to jumping ship.
This inexpensive, understated wearable sports a classic design that users will love as a contrast to the blocky smartwatches that dominate the wearables market today. The AMOLED display is bright and vibrant, and the overall design makes the watch extremely comfortable to wear and very light.
The chip is snappy for everyday use, and in my testing I found the calorie tracking and overall workout metrics to be right on par with my Apple Watch Ultra 2. GPS performance is also strong, as is battery life, which was more than good for the promised 5 days of heavy use in my testing.
There are a bunch of impressive, well-designed faces and an onboard AI-powered assistant that can actually do things, unlike Siri on the Apple Watch.
For the price this is a formidable smartwatch with a great range of features, and well worthy of our five-star rating.

The best Huawei smartwatch for iPhone
Huawei makes some of the best high-quality smartwatches out there for people outside of the US, and up there competing with the best that Apple and Samsung have to offer. Unfortunately, Huawei products are still not accessible in the US, which limits their appeal to the UK and Chinese markets.
The Watch GT5 is the first Huawei watch to feature TruSense, which is designed to provide the highest possible level of health and fitness tracking. The emphasis is on runners and cyclists, although there's plenty on offer for a much wider range of exercise types. The watch interface is clear and large enough to display all the required data while working out.
Choose between 46mm and 41mm models with very little difference in features. Both provide a geometric-style watch face that looks great on the wrist. The watch can be partnered with the Huawei Health app on Android and iOS, crossing platforms.

How to choose the best smartwatch for iPhone
Choosing the best smartwatch for your iPhone requires you to think about compatibility, features, and your priorities. The first thing to consider is compatibility. The Apple Watch is the best smartwatch for most people with an iPhone. It’s designed to work seamlessly with iOS and it offers great integration with Apple’s ecosystem. Features like notifications, messaging, Apple Pay, and health data syncing all work incredibly well. If you want the most out of your smartwatch, for most people an Apple Watch is the top choice.
Consider the features you need the most. The Apple Watch offers a range of fitness and health tracking, including heart rate monitoring, ECG, sleep tracking, and blood oxygen levels. Newer models now offer even more advanced features, like body temperature tracking. But if health and fitness aren’t your priority, many of the watches in the guide above offer support for notifications, app interactions, and even cellular connectivity for use without your phone.
The Apple Watch is considered the gold standard for iPhone users, but other options, like Fitbit or Garmin smartwatches, also work very well with iOS. You may find that they don’t offer the same level of integration but do bring you excellent health tracking features and longer battery life. So if you're primarily looking for a fitness tracker with basic notification functionality, these can be great alternatives.
A downside of the Apple Watch, at least compared to some other brands, is its battery life. It typically lasts a day or two. This means that if you prioritize longer-lasting battery life over advanced features, you may want to consider alternatives from other brands, like Garmin, which can last longer on a single charge, depending on the model.
Since you’re going to be wearing it most of the time, the design of the smartwatch for iPhone you choose will be a crucial factor. Apple Watches come in a range of sizes and you can customize them with interchangeable bands, which makes it easy to find a style that suits you. Other smartwatch brands also offer nice-looking and comfortable designs, but depending on your preferences, Apple has the edge in terms of aesthetics and comfort.
For the best overall experience, especially if you have a lot of other Apple products, an Apple Watch is the clear winner. However, if you’re looking for specific features, like extended battery life or more focused fitness tracking, other brands can still offer a solid experience for your iPhone.
What's the best smartwatch for iPhone users?
Most smartwatches will track your basic health metrics such as steps and calories, while devices with built-in GPS make for perfect running, cycling and swimming companions. Many of the watches here also sync up so you'll receive notifications via your watch, saving you the need to dig out your phone as often.
We’ve fully worn, tested and evaluated all the watches in this list and ranked them based on software and which we think is best for most people. Bear in mind the watch at number one might not be best for you though depending on your needs, tastes and budget.
How we test the best smartwatches for iPhone
Our smartwatch process typically involves using the device as if it were our own personal wearable. That's the best way for us to fully test it and see how it fares in the real world. We do a comprehensive sweep of its features, functionalities, performance, battery life, and ease of use, doing so over multiple days.
Of course, since we also want to know how it performs and which features are available when it's paired with an iPhone, we make sure to squeeze that into our testing as well. Once we've collected all the data and information we need, we take all of it and compare it to the smartwatch's price, finding out if it's a great value for our readers before making a recommendation.
