What iPhone do you need to use an Apple Watch?


Apple Watch: Ultimate Guide to Pick Your iPhone Compatible Smartwatch

Choosing the best Apple watch is a confusing business, not least because Apple sells three different models. The Apple Watch 6 and Apple Watch SE were announced in September 2020 and are available to buy, alongside 2017’s Apple Watch 3. Each model then has two sizes and several different casing materials and finishes with different prices that can make the choice somewhat overwhelming at first. This guide will be highlighting the best Apple watches and overview for each so it’ll be easier to choose.

Apple Watch 6

The Apple Watch 6 is the most high-tech, impressive wearable Apple has made so far. New additions in this model include blood oxygen monitoring, plus a new- and more efficient- the Apple S6 chipset. That extra efficiency helps improve the battery life, especially now that you can track your sleep, a feature that debuted on this model but is available as a software update for others too. The screen has also been improved and you can get the Apple Watch 6 in some new colours, including a flashy red shade.

Apple Watch 5

The Apple Watch 5 is almost as good as the Apple Watch 6, and like that wearable, it comes with a handy always-on display. That will allow you to see all of your key stats without having to turn on your watch’s screen. You’ve got the choice of either a 40mm or 44mm case for this watch, and it comes with a wide variety of fitness features. It also has an ECG monitor, GPS tracking, impressive heart rate monitoring, and lots more.

Apple Watch 4

Don’t need that always-on display? The Apple Watch 4 doesn’t come with that, and it’s far cheaper than the Apple Watch 5, so you may prefer to get this version if you want to save a bit of money. It also comes in both 40mm and 44mm variants, plus a lot of the features are similar such as the excellent heart rate tracking and the larger display than you’ll find on older Apple Watches. The most exciting tech here is that fact that there’s an ECG feature within the heart rate tracker. It can test your heart to see if you’re at high risk of atrial fibrillation, which will allow you to seek help earlier if your health is in danger.

Apple Watch 3

The Apple Watch 3 (or Apple Watch Series 3) was once the very best smartwatch, but it has since been bumped down by the Apple Watch 4, 5 and 6. That said, it’s still a great device. IT comes with a smaller display than the Apple Watch 4, and you won’t get features like the Ecg monitor on the devices above, but it’s still a strong wearable for those wanting fitness smarts. There’s also an LTE version of the watch available, for if you’re in need of a watch that can receive messages or phone calls even when you’re away from your iPhone.

Apple Watch Colours and Sizes

Every new generation of Apple Watch brings with it new colours and case finishes- and the Apple Watch 6 and Apple Watch SE see the arrival of a first-time blue colouring for the aluminium case, with a bright red style available too. Both models are available in 40mm and 44mm sizes- which have been the sizing options since the Apple Watch 4, which replaced the 38mm and 42mm sizes of its predecessor.

Are there other Apple Watches?

You’ll probably notice that the original Apple Watch, the Series 1 and Series 2 device are not on the list. That’s because it’s hard to buy those devices new anymore, you can still source the original Apple Watch and a variety of older devices from some places, but we’d recommend opting for one of the newer devices as they support software for longer and are generally more refined.

What iPhone do you need to use an Apple Watch?

Unlike Google’s Wear OS devices, the Apple Watch only works with one type of phone. You’ll need to have at least an iPhone 5 running iOS 10 or later to be able to use an Apple Watch or Apple Watch 2. If you want an Apple Watch 3, you’ll need to have at least an iPhone 5S running iOS 11 software for the non-LTE version or an iPhone 6 to be able to use the LTE variant. But if you’re buying an Apple Watch 5, you’ll need an iPhone 6S or later, which is the cutoff for watchOS 6, which is what that smartwatch ships with.
