I can’t delete this app off my phone – Guitar : Play & Learn Chords Review

And I can’t sign up without paying 19.99 which is the reason I want to delete this. I thought it would give me a sample to see if I liked it without having to sign up to pay for it first getting 1 week free trial. They should give you a free trial first then have people sign in to pay because this app may not be the right one for me and there are others that maybe a better fit for me.
