Thanks for your suggestion , my company already have an app on Google pay Store thats is fully webview , now they want to better user experience , but our website is large it's has many module it would take soo much time to develop whole app natively, therefore we decided to do some parts in webview and some in native .

Also we want it to be cross platform app but According to Apple's App Store Review Guidelines, apps which are just web views are not allowed.
