Yes, this is actually one of the easiest ways to watch if you are not able to watch through a gaming console. Here are the detailed instructions from WWE:
You must be running iOS 6 or higher and have the WWE app version 3.0 or higher installed to access WWE Network. If you haven’t already installed the free WWE app on your device:
- Go to the App Store.
- Search for WWE.
- Select the WWE app.
- Click Free.
- Click Install.
To view WWE Network content you must be a WWE Network subscriber and signed in to your WWE account within the app. If you are not currently signed in, you will be prompted to sign in when you click on any WWE Network link. You can also sign in by selecting Sign In from the app menu. Once your account has been verified, you will be taken to the home screen and can select the programming from WWE Network that you want to watch.
