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
