Updating your iPhone:

I see you have posted in iPhones. So, this is what you need to do: Backup before you install the update.

1. First: You create a backup of your device.

Go Here: How to back up your iPhone, iPad, and iPod touch - Apple Support

2. Then: You install the update.

Go Here: Update your iPhone, iPad, or iPod touch - Apple Support

As for updating particular application that is not that of Apple, you need to contact the Developer of the application.

All new iOS updates includes security patches.

The latest at the moment is iOS 13.5.1
