How do i activate the vibration for notifications of the keeper app on my phone?

"If you want to set your smartphone to vibrate in the event of a notification - if, for example, a keeper is out of range, you have to activate the folowing settings with iOS:

Open the settings for your iPhone and go to the category ""Sounds"". There you will find the points:
- vibrate when ringing
- vibrate when silent

Both settings must be enabled to trigger a vibration from the keeper app at any time."
