I use this app on a daily basis and find it to be a great tool if you have actually read the book and are following the program. You will not get the full benefit nor be as successful if you only buy the app because unless you have some understanding of nutrition and WHY the program works the way it does, it becomes "just another diet."
$1.99 will NOT give you full access to the recipes (90%of them are locked) so unless you are willing to spend an additional $7.00 per week you are best served by going to your local second hand book store where you will get much more actual useful information in paperback or hardcover.
