Opencart PWA (progressive web app) / Ionic 4 mobile app

Recently Magento launched PWA studio for developers to create mobile apps for Magento websites with customization .
I am planning to create a similar sort of project for Opencart to enable developers create Opencart mobile apps .
We have recently launched Opencart Pwa app in code canyon marketplace that enables store owners to offer mobile app to their customers.
The project is based on Latest Ionic 4 technology.
The basic features are
1. Separate slideshow for app homepage with admin panel settings in opencart module.
2. Featured products on homepage (configurable from module settings)
3. Products with almost all options supported except file upload
4. Webview based checkout so it supports all opencart supported gateways for shipping or payment.
5. My order section
6. Login with facebook or google
7. Push notifications about orders
8. Custom promotional push notifications can be sent from Opencart module that can be linked with any category or product.

Check live demo from play store http://bit.ly/opencartandroidapp

One custom version is also live on Apple Store you can check it here https://apple.co/2Fuyeb6

Or... because opencart is mobile responsive already... create a manifest file and push your actual site as the PWA... so then no need for two separate sites, two separate codes, two separate experiences
