By allowing the buyer to post a review directly through this app but also giving the app owner the option to Approve or reject before going live, my customers can feel confident that their review is in their own words (typos and all) and will be posted upon approval of said review.

This not only gives some of the control of leaving reviews up to the customer (this option allows for customer engagement) but also keeps overall control with the app owner to approve or reject reviews where possible before the reviews go live
