Annoyed by required additional purchase – Instant Abs: Workout Trainer Review

I purchased the annual fitness support from within the app. I received prompt emails to workout. These emails contain a link to Fitness Buddy and require that app for an additional $2.99. Pretty annoyed that that was not included and that the support email address has not responded.
