GD&T HD pro vs Springulator Spring Calculator Usage & Stats
Learn, interpret and inspect GD&T according to ISO 1101. This app describes a large range of definitions of geometric dimensioning and tolerancing and supports engineers and employees as a multimedia reference book. As part of operative education, this app shows relationships and makes it easier to understand the right handling of form and position tolerances in practice.
This app explains the most important definitions of GD&T and its interpretation by examples (straightness, roundness, flatness, cylindricity, profile of a line, parallelism, squareness, angularity, position, concentricity, symmetry, circular runout, …)

Springulator® is a robust spring calculator that features easy-to-use functions, reference diagrams and stress charting for:
• Compression Springs – One-Load, Two-Load, Rate-Based & Dimensional
• Extension Springs
• Torsion Springs
Created for engineers, purchasing agents and designers, the Springulator allows users to calculate an array of information with minimal data input. With only a few fields of data entered, the Springulator provides information to check the stress of a design, calculate spring functions and test spring capabilities.
Springulator calculations include:
• Stress, corrected stress & stress at load height
• Tension, free length, solid height, load at solid height, total number of coils, active coils, rate, deflection, index, Wahl factor, torsional movement & part weight
• Spring stress charts with material tolerance guidelines
• Calculations based on selected materials
• English and metric measurements
• Adjustable initial tension for extension springs
• Emailable and quotable results
