Need a tutorial and place the review request to a later time

I just downloaded this app. The other reviewers were right in the annoyance of the review request at the beginning before Ive tried the app. Give me a chance to use it. Sounds like the other reviews were good and I would have given a 5 star instead of 4.
A tutorial or demo at the beginning would be good. Im not sure what to expect or to navigate.
The flash cards wont let you continue if you mark it wrong. The way I use flash cards is to go through them, then review the ones that I got incorrectly.
