I built a (very simple) game in Phaser a couple of years ago and used cocoon (https://cocoon.io/) to package it up into an Android and iOS app. Basically it packages the HTML/JS/CSS app into a native webview.

Phaser is a great framework. I managed to conceive, write the game from scratch and have it in the app store within a day.

It's no longer on the iOS store as I didn't continue to pay my dev licence, but happy to share the play store link if anyone is interested.
