There is error handling and will inform the user of an incorrect input value, and will let them know what was wrong with the input. For example; wrong numeral ordering, incorrect characters, combo of numbers and letters, etc.

For a more detailed explanation of what a PWA is click here.
To achieve PWA functionality you have to fulfil a number of criteria:
- a service worker to cache the code
- HTTPS
- a manifest.json file
other optimisation criteria:
- various sizes of icon
- address bar theme colour
- configuration for a splash screen
In addition to this, there is a listener for the "Install to homescreen" prompt. When launched as an app it preforms just as you would expect a native app to function.
