Apple made a number of changes in iOS 10, with one of the main overhauls appearing in its Messages app.

The app now offers multiple methods of inputting iMessages from handwritten notes to the Apple Watch's Digital Touch feature. Users are also able to react to individual messages and customise how the receiver sees the messages you send. You can read all about the new Messages features and how to use them in our separate feature.

One of the most exciting new features in Messages is the App Store integration though. This feature means you can download third-party apps and share information from them without having to leave the Messages app at all, whether that's scanning a document or sharing your location.

Here is how to access, download and install the iMessage apps, along with the best ones to download first.

You'll see the App Store icon to the left of the input field when you start a new iMessage. If you can't see it, tap the grey arrow on the left and the icon will appear, along with the Digital Touch option and a camera icon.

After a tap on the App Store, click on the four dots in the bottom left hand corner and then hit the "+" icon that is labelled "Store". This will take you to the App Store designed specifically for Messages.

The left tab is called Featured and this is where you'll find new apps to download and install. The right tab is called Manage. This is where apps you have already downloaded on your device that are compatible with iMessage will appear.

You can choose to toggle them on or off from here, as well as choose whether or not to automatically add compatible apps to your iMessage drawer when you download them on your device.

To download an iMessage app, tap on the one you want and hit "Get" to install it, as you would in the normal App Store. After it's downloaded, you'll see it appear in the iMessage drawer where you found the "+" Store icon earlier. You'll also be able to swipe between the various apps in the drawer below the input box.
