Yes, Edge will have a schedule of activities, but it won't be in the app. She will have to go after it opens for the day (usually at 10 AM) to see what is on offer for the day. They have a little board that they write the activities on. I've attached a picture of the activities from the Dream two weeks ago. My daughter just snaps a picture at the beginning of the day so she can reference it on her phone.
My daughter is currently 13 (about to be 14) and she was SO HAPPY when she was able to go to Edge. Once she was about 10, she was pretty much over the Oceaneer Club and Lab and pretty much only went to Edge after she was 11. She'll be able to go to both Edge and Vibe on our next cruise, but I suspect she'll mostly stick to Edge for now. There's a big difference between a just turned 14 year old and a 17 year old and she mostly likes to hang out with kids at or slightly younger than her own age.
