Apple Watch 4
The Apple Watch 4 is an amazing iPhone Xs accessory that allows you to see notifications on your wrist and details at a glance. The Apple Watch started out as an accessory that I could live without, but after wearing one daily for the past several years it's an essential iPhone companion. Even though you can get one with LTE, you still need an iPhone to use with it.
With the new Apple Watch, you get a bigger screen and other key improvements that add to the growing list of things you can do with the Apple Watch.
The new model can take an ECG, which along with the Apple Heart Study can help alert you to issues with your heart health before it becomes a life or death situation.
The new Apple Watch also runs watchOS 5, which is a free update for older Apple Watch models. If you want to save money look at the Apple Watch 3.
