WoodworkerCalc is a specialized calculator designed specifically for fine woodworking and other crafts. This iPhone app simplifies the process of entering and performing calculations on measurements, while also keeping track of any errors that may accumulate during layout.

One of the key features of WoodworkerCalc is its ability to display and account for small round-off errors in fractions. This is particularly important when laying out repeating units, as even a slight error in the fractions can lead to significant discrepancies. WoodworkerCalc not only highlights these errors but also adjusts the layout to accommodate them.

The app allows for easy conversion between decimal and fractional results, giving users the flexibility to work with the units that are most commonly used in woodworking. Users can choose the precision of the fraction to match real-world working units, with 1/32 being the typical smallest unit for woodworking layout.

WoodworkerCalc also offers a handy feature called "tapes," which allows users to store and retrieve sequences of calculations. This feature is especially useful for preserving and reusing complex calculations in future projects.

In addition to its measurement capabilities, WoodworkerCalc includes a board foot calculator, which comes in handy when purchasing materials. It eliminates the need for manual calculations, saving time and ensuring accurate estimates.

Lastly, WoodworkerCalc features a triangle calculator that eliminates the need to remember high school trigonometry. This tool is particularly useful for woodworking projects that involve angles and precise measurements.

With its specialized features and user-friendly interface, WoodworkerCalc is a valuable tool for woodworkers and craftsmen looking to streamline their calculations and improve accuracy in their projects.
