Nice app Best calculator I ever used. But there's a problem. It force closes/closes after i lock the screen and then unlock it. Otherwise it's a great app. Deserves 4 stars.

Screen blanking resets the application. This calculator is OK. It does everything I need to do. However, the most annoying thing about this application is that if I'm in the middle of a calculation and put my phone down for a few minutes; the phone goes into "sleep" mode to save power... but then when going back to my phone, all of the work in the calculator application has disappeared! The calculator effectively resets and that's the end of your hard work. I don't know about you, but the way I work with calculators doesn't mean I'm always hacking away at the keyboard for answers... I have to go away and think about things. The reset on screen blanking is a MAJOR problem, and most of the time makes me reach for my conventional calculator instead. If you want to make a quick calculation then fine, but I'm giving this 1 star for the fact that most of the time I find it useless as I regularly lose my ongoing work.

Untrustworthy results It pains me to write poor reviews, which I rarely do. Unfortunately, this calculator could result in undetected errors in the simplest of calculations. 1. Most subtractions that result in a "3" showing in the odd numbered decimal digit (i.e., x.3, x.xx3, x.xxxx3) result in a rounding error usually only seen when dividing by 3. The fact that it can occur in a simple subtraction is unforgivable (i.e. 78.9-45.6=). Granted, it can be easily spotted, but it holds that error throughout any complex calculations wherein it will hide. 2. Ambiguous user interfaces resulting in confusion, or worse, unknown false solutions are my largest pet peeve. A button should be something you want, not used as an indicator of the device's state unless clearly indicated. a. Regarding the "Degree - Rad - Grad" key, are you in degrees or do you want degrees? The only way to insure is to do a known calculation, such as "sin(90)" and see the result. It requires the user to verify that. b. In "programmer" mode, it has no indication at all if you are in Octal, Decimal, etc. Unreliable results = 1 star.

Best calculator I have ever used So u functions, can be easily operated by single thumb. And best part it's free from irritating ad s. I use it on HTC mobile and earlier on Samsung, i found it equally good on both. Very happy with it.

Ali A at Oct. 23, 2014

Garbage and dishonest I confirmed that this app gives errors on the most elementary calculations as described earlier(eg Aryu). The author also deceitfully rated his app no. 1 in a supposedly unbiased review(on Androidforums) and continued to insist on being unbiased after being uncovered. He also said maths was his obsession, which seems unlikely when the calculator is so unreliable.

The best one Just a perfect handy scientific calculator for engineering students like us...Best in class :)

Daniel Power at Nov. 19, 2013

Decent calculator app. Doesn't stand up to Realcalc or Calculator++ The interface is very appealing. However the lack of a portrait display mode ruins it for me. The second issue is that having a single button for both a beginning and ending bracket, means that you cannot have nested brackets. Which is a crucial feature for a calculator which has function display. Calculator++ gets around this by allowing the user to slide left or right on the bracket button to get a left or right bracket.

Doesn't save numbers If your phone screen shuts off in the middle of a calculation it deletes the current calculation.
