How can I change the Pulse app notification sounds and vibrations?

In Android 8 or above you can set the notification sound and whether the phone will vibrate of not by going to the Settings menu and clicking on “Notification”.

For older versions of Android you cannot change the notification sound, only whether the phone vibrates or not.

For all versions of Android your phone will vibrate once for a good measurement (all values within range) and twice for a bad measurement (any measurement outside of required range).
