That wasn't too hard, but obviously a non-programmer would have difficulty understanding it. But hopefully and quite possibly you're working on a better interface, so not much of a problem for the time being.
I've got another piece of feedback. The numbers seem to be off for me in the web app. I t says I have over 300 pages bookmarked, while the interface only displays 100(which seems like the more plausible number).
$5 is kind of a norm these days, and a lot of times, its too high, depending on what the service is. For instance, there's IRCCloud. Obviously, the interface is good, and they provide easy to use mobile apps, but all that doesn't justify $60 per year. Another example is Pocket. I really like their apps, but they also followed the $5 norm. They aren't providing me much value to be worth $5(every month) to me, so I switched over to Pinboard(which, by the way, is one of those few services doing pricing right these days). There are a lot of services that I can justify paying $5 per month for, cloud storage for instance, but a bookmarking service, nope.
If you want to see the kind of backlash Pocket got for pricing their Premium option at $5, just have a look at this thread on reddit:
