Specora

SPECORA is an engineering specification studio for iPhone and iPad. Turn dimensions, tolerances, materials, and components into a structured technical library you can maintain and analyze.

Start with a part or a specification. Define its parameters, explore dimensional limits, compare design alternatives, and keep a clear revision history. Bring the results together in a specification sheet you can export and share.

BUILD YOUR SPECIFICATIONS
• Create mechanical, electrical, material, and custom specifications.
• Define parameter names, values, units, and tolerance deviations.
• See nominal, minimum, maximum, and total tolerance values.
• Set your own minimum and maximum rules for nominal parameters.
• Start from reusable templates or import parameter data from CSV.

EXPLORE TOLERANCES
• Analyze symmetric and asymmetric dimensional limits.
• Compare worst-case and root sum square (RSS) tolerance stacks.
• Build signed dimension chains and drag terms to reorder them.
• Calculate minimum and maximum shaft/hole clearance.
• Identify clearance, transition, and interference fits from entered limits.

COMPARE AND REFINE
• Create alternative scenarios from an existing specification.
• Compare material selections, mass, dimensions, and tolerances side by side.
• Highlight values that differ from the current baseline.
• Preserve revision snapshots when saving specification changes.
• Compare parameter values and tolerance deviations between revisions.

ORGANIZE PARTS AND MATERIALS
• Build a personal component library with custom groups.
• Link parts to their specifications.
• Create assemblies and edit bills of materials.
• Calculate total component quantities and estimated assembly mass.
• Define custom material density, modulus, yield strength, thermal expansion, and cost.
• Keep material sources and notes alongside their properties.

KEEP YOUR ENGINEERING KNOWLEDGE
• Save reusable parameters, templates, formulas, and standards notes.
• Evaluate custom arithmetic formulas with named variables.
• Search specifications, parts, materials, parameters, formulas, templates, and revisions.

USE TOOLS IN CONTEXT
• Access 45 calculations across dimensions, tolerances, materials, mechanics, electrical quantities, and construction.
• Add calculated results to specifications as new parameters.
• Convert and compare units across 13 quantity groups.
• View parameter conversions while retaining the original value and unit.

EXPORT YOUR WORK
• Generate PDF specification sheets with parameters and revision history.
• Export specifications as CSV or JSON and bills of materials as CSV.
• Share files through the native share sheet or print with AirPrint.
• Generate QR labels containing a local specification ID.
• Scan or enter a code to open a matching specification in your local library.

A focused document-style interface brings your engineering library to iPhone, with a dedicated sidebar workspace on iPad. No account is required, and your library is stored locally on your device.

SPECORA provides calculation aids and user-defined rule checks. Results depend on your inputs and material data; they do not certify engineering safety or standards compliance. RSS results assume independent deviations and represent statistical estimates. QR labels open specifications already present in the receiving device's local library.
