CNC Machine Calculator Pro app for iPhone and iPad

I am a machinist/ CNC Programmer and I wanted a app that had functionality that I need. I designed this app with speed and ease of use in mind. I included features that I use everyday. It makes my job easier. It includes the following features:
-Inch Tap Drill chart
- G code and M code list
- Inch and metric drill decimal chart
- drill point length calculator which can also be used to determine spot drill offsets
- a true position calculator
-a height stand calculator (my favorite) which I use when I am checking the distance from a diameter centerline to another feature
-a sine plate block build up solver
-a right angle triangle solver
-polar to cartesian conversion
-a bolt circle calculator (up to 12 circles)
-inch and MM speed and feed calculations
-GD&T guide which I used my own words that make sense to read
-Horsepower required

I am willing to add functionality at your request. I am also offering a link to my tech support blog.
