Question on about page pad – NeuraCache: Learn & Remember Review

I don’t understand what you get by subscribing to the $1.99/month plan besides getting a 30 day free trial, But don’t you get that free trial with the premium also? What do you get with the $1.99/month vs the free app (that you say is always free)?
