#1 – HandyCalc Calculator by mmin

HandyCalc Calculator is our choice for the top calculator available on Android today. This app give you a lot of the basic Investment calculator functionality of a TI-84, including all scientific calculator capabilities, graphing, and the ability to solve systems of equations. Answers can be returned in fraction and radical form or converted to decimals. There are also simple copy and paste capabilities, something that should be available in more apps. The app even comes with a demo doc and a link to a video tutorial. There’s a lot to like here, and even if it’s not perfect, it comes as close as anything we’ve seen.

Pros: Free, scientific and graphing investment calculator online capabilities, solves systems of equations, returns both exact answers for fractions/radicals as well as decimal approximations.

Cons: Missing features of a typical grapher such as max/min, intercepts, etc.; swiping between keypads presses buttons and feels awkward; two different “equals” buttons (which perform different functions) can be a bit confusing.

#2 – Scientific Calculator by Kreactive Technologies

Scientific Calculator had the nicest UI of any calculator app we reviewed. Buttons are attractive, with a nice top-lit effect, and a good size, making them easy to press. A flick scroll or double arrow button allows you to easily access scientific functions. The calculator does feature some basic graphing capabilities. This calculator comes very close to 2-line functionality. You can enter an entire calculation before pressing enter. Then you can return to previous calculations by long pressing the input area. There are more powerful apps on this list, but UI is important in an Android app, and Scientific Calculator has a great one.

Pros: Free, attractive UI, some functionality of a 2-line calculator, some graphing functionality

Cons: Graphing functions limited; comments in the market indicate some users confused by lack of +/- button, although we found this easy to work around.
