Wow, thanks for sharing, and for the detailed write up! Please keep the feedback coming (I'm j@pop.com if you'd like to keep in touch in the future).

I do agree Screenhero should have had a more generous free tier. With Pop, we will likely have a free usage tier when we start charging. We haven't mentioned it on the pricing page just yet since everything is currently free and it would complicate the story.

I love the analogy you've made with Adobe Acrobat Reader! We definitely want Pop to become the default tool you'll use when you want to work remotely with someone on a task together on your computer (pair programming today, but a whole lot more in the future). And I agree that keeping a generous free tier will help us enable that, beyond just the ability to join calls started by paid users.
