4 stars: Very good calculator, lots of useful features (like constants, and complex numbers) and good personalisation. Only thing that could be added is a graph and a derivative/antiderivative function. Edit: Thanks for the reply Dev! Good to know!
4 stars: good app but some areas need improvement such as 1. ac and back button should be at lower side for bigger screen size it difficult to clear screen and delete some digit. 2. option for one hand use is missing please do these to improvement.
4 stars: Nice look-and-feel, and it does what I wanted it to do. But my most recent hardware pocket calculator had statistical functions. Admittedly, these might now best be performed within a spreadsheet package; but are there any plans to add statistical functions?
5 stars: Very nice, powerful and elegant scientific calculator with no adds. I've been using it for a while and it's as powerful as a real calculator and you can do even more with more with some versatile options created to add more functionality. Try it, you'll use it more than a real calculator.
5 stars: my TI-89 messed up, i went tonthis as a back up. works great
4 stars: Used for my statistics course. Only thing i didn't like was it doesn't show you the previous calculation
5 stars: Very good application for both science and engineering students. Thanks for developer. For the premium version, let anybody that wish to download do it may be with higher megabytes instead of money. Thanks.
