WRT the android/ios app question: Why do you want to implement a native app?
Seems like a significant investment if you're already meeting user needs with your PWA offering.
It's definitely punted for now as I continue to round out the product. When the time comes and we're ready for an official mobile offering, we'll evaluate the current solutions out there (the landscape is always changing!)
If you do reach that point, I hope you share the factors contributing to your decision.
