Dangerous

I used this app to determine PG for two planned dives. The results for the first dive were fine but the PG for the second dive was way off. I ran the dive through the RDP calculator and then through the dive tables, the results from the iScuba Plan app were off.
The interface for this app is great but if the results are faulty the app is at best useless, at worst very dangerous.
