For a new user, they may have no idea that this is a 30 day trial until they download and run the app, and I don't think that there is pricing information on the website anywhere. Not necessary to have any of this, just some feedback :)
Our pricing page goes into more detail -- https://www.realartists.com/pricing.html
You're right, though - we should mention the free trial part on the front page. Thanks for the feedback and for trying it out!
