Pocket Trainer App: Your Thoughts??

Options
I'm getting a little bored with my workout routine and wanted to know if any of you have experience with the Pocket Trainer app. I just need a little direction when I hit the weight floor... I do well with guidance, love going to classes like Step and Kickboxing, but I lack the motivation or know-how when I just walk into the gym to work out on my own. In my ideal world I would have a personal trainer, but with xmas coming, we need to save the cash! Any opinions/thoughts? Thanks in advance!
