Please consider being more explicit that this is a freemium product. You state it in the post, but pricing is nowhere to be seen on the index page. Until you sign up, I suppose. It's probably not done intentionally, but it's effectively one of those annoying sneaky anti-patterns.
Ironically, the lack of prominence of pricing is due to me hating how often apps remind you you're not paying. I didn't want it to be in everyone's face, all the time. Probably bad UX and business on my end...will fix shortly.
