Yes, if the underlying engine is designed to support it. There are standard web APIs for accelerated graphics, compute, offline storage, Bluetooth, push notification, environmental sensors, phone book access, camera, local storage access, and so on… A decent PWA is indistinguishable from a native app.
Can PWAs perform just like native apps when it comes to smoothness and optimization?
