I'm so sorry, but unfortunately Apple requested that we remove that feature and we were forced to comply.
We are working to introduce a new version of this feature shortly, but in the meantime, I have good news for you. Every copy of Just Ahead has a built in free trial. Just tap on Find a guide, then tap on any guide, then tap Download Sample. The guide will start downloading. Once it's done downloading open the guide. You'll be able to experience up to 20 of our stories for free! Let me know if you have any problems with getting this to work.
Again, I'm so sorry for the confusion.
