WORA code base - corodova/ionic app for mobile,web clients

Hi Everyone.

I would like to thank people for this wonderful product and open source characteristic of this.

I am working on an idea myself, where I am able to use nextcloud. I am liking this so far.

I have a question: I see separate code bases for android, IOS and web app. I was wondering if there was an attempt to do a Write Once Run Anywhere (WORA) platform based app to run Android, iOS , and Web client apps for nextcloud. If so, kindly point me there. if not, curious to hear your feedback. Also if I were to implement what platform would you recommend?, are you open to contribute?.
