Way better than the construction master

This calculated app far exceeds the capabilities of the construction master pro trig model. The developer updates it with new functions all the time. I highly recommend this app. I have not used all the functions but there if need be. Im running the iPhone 4s and it runs perfect. I will refer to others. Thank you for a perfect app. Much appreciated.
