OS updated now app won't open – BuildCalc Review

This has been a great app! However, it won't work since my OS updated last weekend. Tried to contact app support but page cannot be found. Please update and fix! Needed to do roof calculations last week and it wouldn't work and I had no backup in the truck. Put me in a real pickle!! 5 stars if support was available and on the ball!! UPDATE!!!!! Found email adress for the developer and sent him an email with my phone # attatched. The guy called me back within 30 minutes!! He was at the store with his family on Sunday no less. Went straight to work on the problem and had me straightened back out in 45 minutes. All I can say is WOW! Changed to 5 star! Would give him 6 out of 5 for customet service alone!! Great response and thanks to BuildCalc!!
