Always know when - and how - to block.

An intrusive or overbearing app can make your Android Wear experience a pestilence, whether it means to or not, but thankfully, there is something you can do about it. It's called the Block app notification list — but we just call it the blacklist — and you can use it to screen apps from your watch and make sure that when your wrist buzzes at you, it's something important, and not just a reminder that you're regenerated all of your lives in your game of the week.

Here's how to banish an app from your watch.

You can block an app from almost any of its notifications right there on your watch. Just swipe all the way over past the right-most cards and buttons — past Open on phone — and you'll find the option to Block app. This will add the app to the blacklist, where it will stay. If you accidentally click this — or wish to remove an app from the blacklist — you'll need to head to your phone to fix it.

Three clicks to notification exile.

In the Android Wear companion app, you can access the blacklist by clicking the settings gear in the top bar. The first item in the settings is the Block app notifications list, and from here, things are pretty simple. You can add an app using the floating action button at the bottom of the screen, and you can remove one from the list by tapping the X next to that item.

Are all of your apps free to foray onto your watch with notifications, or do you have a longer blacklist than McCarthy? Do you wish that you could have more refined controls — similar to the priority notifications settings for Android Lollipop notifications — or are you fine with the simple allow/deny controls provided now?
