A utility calculator that is specifically designed for the needs of the construction tradesperson. It features an easy to read display even in high glare environments. Keys are designed for large fingers and fractional values are easily inputed with a single swipe of the finger. Results are reduced to their simplest form with rounded results displayed in red.
Full access allows for the solution of triangles. Simply enter three known measurements and let FractnCalc generate a solved triangle. Select from five display resolutions (1/4 to 1/64). Calculated area is also displayed. Invalid triangles and ambiguous triangles are displayed in red.
Disclaimer: Although every attempt has been made to assure accuracy, due to the nature of fractional calculations, slight errors may result. Triangle graphics are not drawn to scale. Use at your own risk.

WOW! No More Wasted Time Doing Math
I wish I had this app years ago! Working in the field as an electrician, I am no longer wasting time on my calculator doing math. I just enter the inches on the GIANT keypad, use my (fat) thumb to adjust the ruler to match my tape and I’m ready to calculate! It’s so EASY to calculate and then make my tape match the graphic. Brilliant design! A total time saver.
Best thing since sliced bread
I always buy extra lumber knowing that I’m going to measure and cut wrong...like a lot. This app has helped bring that waste down to almost nothing. I would pay good money for this app. Thank you so much for making such a great tool. I use it all of the time.
The Perfect Fraction Calculator
I hate fractions but as a construction electrician I use fractional math all the time. When will the USA adopt the metric system for crying out loud? Until that time comes, I now have a simple tool in my toolbox that takes the pain out of dividing 13-7/8 inches in half. Thank you Mr. Ray Desnoyers for your creativity, ingenuity, and programming excellence!!
