In an effort to conserve memory and keep your iPhone running smoothly, iOS may automatically close apps running in the background if there are too many apps open. If Driver’s Little Helper is running in the background, it may be closed automatically by iOS, which will stop monitoring and alerts. If you want to run the app in the background, we recommend closing as many other apps as possible. To close apps, press the Home button twice to see all currently running apps and then swipe the apps that you would like to close upwards.
