I´ve used Ionic for both mobile apps and PWA (web sites that access the device hardware). It is pretty straightforward to do both in Ionic. As a side comment, the other day I wanted to do a very simple single page "app" (I jog, so I wanted a "sonar" kind of app that told me how far to my target speed I am, constantly). I thought I was going to give native Andriod Studio a try... as this was a very simple app and I was going to use GPS functionality, it sounded right. I was badly surprised by the way UIs are built in Android Studio, it is so fugly, it took me back to the AWT/Swing framework I worked with in the late 90s. After battling with the ConstraitLayouts and other bullshit, I went back to Ionic to do a simple HTML layout and had the app working in 1 hour. I can't believe in 2019 that is the way Google is making people build interfaces in Android.
