Hi - for a responsive Bubble app running on either iPhone or Droid (or a Pad), can I have a button in the app open a specific native app on the smartphone, ie Waze, Twitter, FB, etc.
The button in the app would not be expected to open any native/installed apps on a desktop/laptop. The use-case is only for smartphones and pads.

If you visit that page on mobile and scroll to the bottom, clicking the “tweet” button will launch Twitter on your mobile device. I didn’t do anything special besides create the button code using Twitter’s own interface:
