The most useful support app I have for accurate measurements. Clearly a lot of thought went into designing this tool. The interface is designed the way a non-mathematician like myself thinks when trying to quickly convert decimals to fractions and vice versa. A whole number and a written fraction with a number on top and one on the bottom. Very easy to use and an incredible time saver.

WillyHi ,

Great app!

This is my “go to” calculation app when I am working in my woodworking shop! It is extremely easy to use and relieves a lot of the headaches in calculating critical fractional and decimal calculations. Are use it every day and I am very happy that I have it in my “toolbox“! I highly recommend this app! It’s a very stable app and has never crashed on me. You cannot go wrong with this app if you need to calculate fractions and decimals.


Time Saver / Error Avoider

I never write reviews - but this app is the exception. While it may be a great mental exercise to add fractions the old way - you’ll never regret using this app even if you just use it to check your work. Me I prefer to use my brain power for other things and save a whole lot of time from the start!
