ChippyCal is being built to make everyday carpenter calculations faster, clearer, and more useful. The goal is not to cram in random functions. The goal is to focus on the measurements, layout work, and job-site workflows that actually matter.
On real jobs you often end up working with people using different measurement systems. Some drawings are metric, some materials are imperial, and different trades often prefer different ways of working. ChippyCal shows both at the same time so you can move between them instantly without switching modes or doing conversions in your head.
Whether you're working old‑school imperial, modern metric, or constantly switching between both, ChippyCal keeps the numbers clear. Enter a value in either system and the other updates instantly so you can work the way you prefer without stopping to convert.
Useful for roof work, stairs, framing, and quick geometry checks when you want answers fast and do not want to fight a generic calculator.
One of the main ideas behind ChippyCal is making framing calculations quicker. Enter the studwork measurements, spacing, timber thickness, and layout choices and the app generates the full framing layout plus a complete cut list of every part so you can start cutting immediately.
Keep useful measurements together instead of constantly retyping them. The aim is to make it easier to stay organised and move from numbers to cutting faster.
Stud Mode helps you quickly move from basic measurements to a full framing layout. Enter the run and rise, choose your stud and nog centres, and ChippyCal calculates the uprights, noggins, timber totals, and sheet counts automatically.
In this example a 10 foot run and 8 foot rise wall is calculated with 2' stud centres and nog centres. The calculator returns the diagonal check, upright lengths, number of uprights, nog layout, and total timber required.
