Nightstand app that closes notifications?

[Meltdownblitz]

Using your iphone as a nightstand for the time and alarm is cool, but I find it pointless if I wake up in the middle of the night or even look at my phone at anytime to see the time and it's covered by notifications. Is there any app that like automatically closes then? So at anytime I look at the clock I'll actually see the time and not some notification? And I know I can use airplane mode but I was trying not to use that, because sometimes I lose calls and texts. So any Nightstand app that closes notifications or blocks them until the app is closed would be awesome. Thanks.
