With two monitors, in a remote-work world where you don't see others getting up for that next meeting, despite all other efforts, this is the first tool that has worked for me every time. How? 1. It's full-screen, and forces you to engage (unlike the notification that appears in a part of the screen you're used to ignoring (say, because you also get email notifications that way, or slack messages). 2. I set it to appear just one minute before my meeting, which means whatever I was doing I need to stop doing right now. I can hop on the call and if others are late, I can go back to what I was doing for a minute. 3. It has the ability to open your video link invite from the full-screen takeover message, which also saves a step. (By contrast, when you see the notification and you click on it, it sometimes doesn't activate, and even when it does, it opens up your calendar, and then you need to click 2 more times). 4. When people on one call see it if I'm sharing my screen, it's a reminder for everyone "hey, this meeting is ending" and serves as a way to wrap it up for everyone. (Those folks don't want to be the ones who make you late for another meeting.)It works. It's the first product that works for me. I historically have taken the attitude of "I am not paying for apps that are for work", but I realized $20 is a stupid small amount of money to pay for a service that makes me seen as responsive and on time - all the more critical when you're a remote employee. Since then, I've also purchased a few other app store apps that help me to be productive. I don't like thinking about how to function at work without it.
