ParaPlan for iOS provides visual and audio confirmations when actions are performed.
Visually, a popup window with a confirmation message will appear. The driver needs to press close to dismiss this window. By default, this is only displayed on the first 10 actions. The idea is to get the driver used to the actions and when they are finished. After 10 times, it is assumed that the driver understands the correlation and the modal confirmations are no longer displayed. If the driver prefers the confirmations (maybe in a poor data coverage area), they can go back to settings to turn this back on.
The status bar will also turn blue and display a confirmation message in the case of a performed action. It will also turn red and display an error message if the app encounters an error.
Audio confirmations will only play if the iOS device is un-muted. These can be also be silenced in settings.
