Very good
It seems it is not updated any more! i bought it and I thought it will continue to be updated regularly with new schemas
Not worthy for the price
Not worthy for the price , would like to get refund
Great resource. Worth the one time fee.

Content excellent, searching needs some work
Overall, highly recommend!! I have used this so many times in many contexts to learn and to refresh on certain conditions and thought processes. The search-ability of the app needs work but thatβs minor compared to all of the benefits.
