SwiftAbout SwiftCalcKit
SwiftCalcKit is an independent calculator project built to make everyday arithmetic useful, understandable, and easy to check.
What the first release covers
The first release contains twenty tools for academic grades, percentages, dates, and time. English and Simplified Chinese pages share the same calculation engines and explain the same assumptions. Home improvement and finance tools remain part of the future roadmap; a tool appears in the directory when its implementation and explanation are ready.
What you can expect
Calculations run locally in your browser. Each tool identifies its inputs, shows a formula and a worked example, and explains boundaries. Examples are illustrations, not customer stories. The project does not claim academic, financial, medical, or professional accreditation.
Corrections and development
We improve the toolkit through reproducible checks and feedback. If a result differs from an official record, compare the model and inputs first, then send a correction report with non-sensitive sample values. Our contact form is the current support channel.
