I need an iOS App that temporarily renders another app inoperable.

Because deleting and redownloading Ivory every time I need a break from someone, is annoying.

“Please stop this app working for four hours, because I’m angry or upset, but don’t want to have to delete and then lose my preferences and logins and then do that whole setup dance again in four hours when I’ve calmed down”

@james focus profiles can do that, although it’s easily bypassed.
