Carpenter's CalcPad1.08 - Google Play

The Carpenter's CalcPad is designed to behave as a calculator, allowing you to to press the same buttons in the same order you would a regular calculator. However; this calcpad provides much more functionality for those that need it. For example, the carpenter's calculator gives you the ability to enter numbers in feet and inches with decimals or fractions, keep track of multiple running totals, change previously entered calculations, insert new calculations into a running total, add labels for variable substitutions and much more.

The calcpad also has a spindle/baluster/board spacer for planning staircases, railings, banisters, decks and other projects. Just enter the details of the the project (which can include two separate distances between balusters) and it will provide a set of board configurations to choose from. After you choose a configuration it will generate a starting/stopping location, plus a label, for each board and display the results in the calcpad. Afterward, you can modify the spacing or change individual boards in the calcpad as field measurements require. Instead of generating spacing requirements, it's also possible to visualize the project as an overlay on preview camera of your device.

After the calculations are complete, the contents of the calcpad can be saved to multiple files and reloaded for later use.

Enhancements and bug requests are appreciated, but I can't guarantee that any requests will be addressed.
