All this talk of a free tier, but I can't see any information about it on the website or app store. Is it the "Free Trial", which indicates to me that it's a time limited demo?

I want this information before installing yet another app that appears too expensive for the value it provides. If I think the free tier might work for me, I'm much more likely to be convinced to go paid once I experience the value it adds to my life.

If this was $8/month I probably wouldn't have given the price a second thought, even though I'm fully capable of basic math.
