Im trying to figure out in a general sense (even if its possible) how you would go about having an app send push notifications at a preselected time, when the app is off.
Like you set a timer for 10 minutes, the close the app. The timer still rings after 10 minutes. The app is closed still. Is the process one of handing off notifications to the OS?
Feel free to link any documentation that may be useful in this regard.
