You've been using Siri for 20 minutes, and when you exit out of the voice assistant, you notice you have 18 new emails, 9 texts and 2 missed calls. Apple doesn't let banner notifications pop up when you're in Siri. However, you can change this if you have a jailbroken iPhone. If you want to avoid missing a potentially important message while using Siri, Unveil is the app for you, because it allows banner notifications, letting you see whenever someone gets in touch.
