I concur - please put pricing in the FAQ. It's a great service, you shouldn't hide the cost. Maybe I'm missing it on the front page, but I couldn't find the price anywhere (and only saw that the download is free, which is different from the price of the service, and of course holds no value without the service).
The service is looking great, and I'm glad you guys have a clear (and super reasonable at 9.99$/year) business model from the start!
