Honestly I did not know about Buzzkill. I suppose the big differentiator is that DoNotNotify is absolutely free.

Well yeah, it's great that you made a free app that can do similar things, I was just pointing at an alternative that folks can try.

Glad there are other options! Before Buzzkill I used another app that stopped being maintained and then stopped working on newer Androids. I had to deal with notifications for a year before I found Buzzkill.
