Gmail on your iPhone can now help you settle a tab with a friend. A quiet update to the iOS app has introduced the ability to send and receive money using Google Pay. As on Android devices, Gmail sends the payment as an attachment -- the recipient only needs an email address to receive their money. The feature might not be as simple on iOS given that you need to download an app to use it, but it's easier than some third-party apps and more widely available than Apple Pay Cash.
