Bodyguard

What it does

Splits everything arriving at you into worth-answering, deal-with-later and probably-ignore. It never replies for you; the triage is the whole product. It runs when you ask it to, rather than on a timer.

Before you install

Open the share link and read the instructions it carries before you add it. @liam_fallen shared this one publicly, and adding it copies the setup into your own account rather than giving you access to theirs.
