Right Angle is a calculator built for carpenters, builders, surveyors, machinists, and engineers — anyone who needs to solve a triangle, a trapezoid, or a circle without reaching for a notepad and the law of sines. Enter any valid combination of sides and angles and Right Angle solves the rest, including perimeter and area. The right triangle calculator is included for free; every other shape unlocks with a one-time Pro purchase or subscription. SHAPES • Right triangle (free) • Oblique triangle • Isosceles, right, and general trapezoids • Full circle — enter radius, diameter, or circumference • Segment of a circle ANGLE FORMATS • Decimal degrees • Radians • Degrees / minutes / seconds (DMS) • Percent grade • Pitch (x-over-12) LENGTH FORMATS • Decimal — the original, unitless entry. Best for metric. • Feet, inches & fractions — type values like 2' 5 1/2". • Inches & fractions — type values like 40 1/2". Pick a fraction precision from 1/2 down to 1/64 inch. Inputs and outputs both use the format you choose, and you can switch any time from Settings. DESIGNED FOR THE JOB SITE • A custom on-screen keyboard puts the symbols you need — feet, inches, fraction slash, degree, prime, double-prime — one tap away. • Helpful errors when an input combination can't be solved, instead of silent failures. • Available in English and Spanish — iOS picks the language to match your device. • Full VoiceOver support across the keyboard, input fields, shape diagrams, and results. Animations respect the Reduce Motion setting. EULA: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy policy: http://rightangleapp.com/privacy.html

Pipe Saddle Layout Calculator is a iPhone app that provides the fitter with the points to make an accurate cut (fish mouth, cope, etc) for piping (cylinder to cylinder) intersections. This app is intended to be used by fitters, welders, fabricators, or anyone who needs to join two metal cylinders at any angle. Are you still carrying that blue book around? Pipe Saddle Layout Calculator is the modern piping blue book. Confused about how to layout cut lines for joining two pieces of pipe? If you are a pipe fabricator, welder, or fitter who needs to make perfect saddle cuts, then this app is for you. Forget books, calculators, compasses, ancient saddle layout procedures, laptops, expensive CAD programs, mathematics or internet access to figure out how to make that perfect saddle joint. Pipe Saddle Layout Calculator is easy. Pipe Saddle Layout Calculator provides the offset layout dimensions for that perfect pipe joint. This calculator works with any size pipe, any angle of intersection, and any wall thickness of pipe. User enters: main pipe, branch pipe, wall thickness (this app considers wall thickness, you don't want to leave too much metal, or take too much off) and branch angle. The calculator does the rest. This calculator produces an on the fly ordinate table of the offsets. The beauty of this app is that it also produces full size pattern templates, so you don't have to measure and layout all of the work points. Now you can print out your pipe pattern templates for any size and any angle intersection. This version outputs patterns configured for an 8.5 X 11 (everyone has access to one of these), 11 X 17, and 24 X 36 printer sizes. So with this app and a 8.5 X 11 printer, the user can still produce any size pipe coping pattern. The calculator is very versatile. Presently input and output is US based imperial and/or metric. Output is feet, or feet and inches, decimal or fractions (to 1/32"). This app has been updated to support metric solutions. User can control how much cut line accuracy he/she wants by setting how many control points are desired (infinite amount, user can get 8 control points, i.e. every 45 degrees or 360 control points, i.e every degree, or more). Most books only give 8 or 16 control points. This app allows an infinite amount. For example, a 2" pipe needs fewer control points than a 48".
