Non-Web App Redirection


So, I have figured out a way to redirect my app to a maintenance page when viewed on the web, but for those with the app already downloaded on their phone, this won’t be the case. Has anyone found a solution to point their users who have the app downloaded when making major changes?

I’m talking about changes that will take at least 30min-hour. Smaller changes I try to slip in when most users are asleep.
