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.
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.
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.
Horrible. Cant get in app. Im not sure if its because i have an android. Please fix, then i give 5 star. Im going to guess that the pro edition of this also has the same issue.
This one is the most versatile calculator on play store. It has almost all the features and best and most logical gui. Kudos to developers. :)
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.
Just a perfect handy scientific calculator for engineering students like us...Best in class :)
Simplest nevigation across the screens, best graphics, and most powerfull features. It is the best calci i have ever used on mobile. It simply works as it says in fact more efficiently. Hats off to the developer.
This is by far the best calculator app I've come across as it has different scientific, statistics and programmer modes and the best GUI.
Value of 4P0 is one but this pi calc shows math error !
Bst scientific calc i hav cm thru on playstore..highly efficient n accurate!!!
When I surfed in playstore...I found it luckily..awesome applications...every professional must have it..kudos to developer...:-D

This is the best calculator app and its ad free and free
Excellent calculator in recent times
Best scientific calculator app in market!
Pi scientific calculator is multiuses calculator
Excellent calculator with full features. ..
Easy to use and nice looks
Use this all the time for engineering, really useful
Beat free calculator
Best calculator app i used
If your phone screen shuts off in the middle of a calculation it deletes the current calculation.
This is the best calculator ever!
Very good app. Very much helpfull..thnks for it...
it's working & verry good app...!!!
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.
