User Reviews
I have only used this for 10 minutes to do some fractional measurement calculations, but I may vey well purchase the full version come next week. I love the fact that you can actually edit the fractions! I am of the mind to believe it is very much worth the 5-spot they want for it. 04/02/26 Best Calculator app out there & worth every pence.
I have the paid version. This is my go-to app when I want a calculator with advanced features. But it needs better documentation, and it's missing a few features (or they're there, and I can't find them, such as adding and subtracting clock times took too long to figure out - didn't think of the °'" key). Also, sometimes I get wonky answers, such as when taking the square root of a mixed number that is input with the fraction key rather than the mixed number key. I would think both should work.
First, the graphics are great! Makes the phone look like an actual calculator. Next, functions are grouped perfectly--easy, quick access. No glitches/screen freeze, etc. Put together very well. Thank you! This is the correct way you get people to buy a product--create a great app, DON'T put a bunch of annoying ads in their face. Once they see how amazing it is they WANT to contribute a few dollars. I would have paid more for this calculator ($10) -- it's SO much better than the others.
Great calculator. Easy to use and has a lot of features. It would be nice to see some financial solvers included. Also it would be nice to see parenthesis matched by color. I tried creating a graph using "sin(x)' by following the instructions in the Help but it doesn't plot a graph, it plots a straight line, so I'm not sure what I'm doing wrong. ANS: I need to set the "Angle Unit" in the Calculation settings to "RAIDIAN".
