Then people realise that what you're doing means a 'dedicated' app is a better experience. At this point, the correct choice would be to have someone create a desktop app that uses your existing web app as an API. If your…
"The correct choice" was only correct after the application was created and iterated upon and somewhat widely adopted. Would any of the rapid feature iteration and widespread adoption have happened if this theoretical application was _initially_ created as a native app?
Yes. Desktop applications can be just as quick to develop and iterate on as web based ones. Slapping together a winforms UI in visual studio is still the quickest way to get to MVP status.
