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.
