Built by engineers. Every method cited. Every output traceable.
RJF Industrial Design Apps builds engineering calculation software for technical design, preliminary sizing, internal review, and report-ready documentation.
Why We Exist
Engineering calculations should be transparent.
Many calculation tools produce results without showing enough context. RJF applications are designed to keep input data, assumptions, method references, and outputs visible from the first screen to the final report.
The goal is simple: help engineers, students, and technical teams prepare preliminary calculations that can be reviewed, checked, and documented.
— Traceable Calculations
No black boxes. Cited method, clear output.
Every RJF application is built around a documented engineering method. Inputs are validated, assumptions are shown, and outputs are formatted for technical reports and review.
This approach makes the results useful for preliminary design, internal checks, vendor discussions, and engineering documentation.
Future tools. Same standard.
Additional engineering calculation tools are in development. Each future RJF application will follow the same principle: clear input specification, a documented calculation method, and outputs that fit a formal engineering workflow.
