Calculator Plus – finally, the Android calculator we’ve been waiting for [Freeware]


You know what’s weird? When you search and search for a calculator to use on your mobile phone and can’t find one with the most basic function ever on it…a percentage key.

I know this, because I’ve been searching for just such a product over the past 6 months without success. The calculators on the Android market have either been massively complex scientific versions, overkill for my needs, or so simplistic or ugly that you wouldn’t want them anywhere near your face at the best of times.

But now we’re pleased to say we’ve found a superb free calculator which delivers exactly the right kind of functionality for ordinary people, not too much, not too little. Calculator Plus Free also looks beautiful, the sort of app you want to install and use on your shiny smartphone. It sounds trivial, but in these cases looks do matter.


There are some lovely features built in too, which make this a top winner in our books. For one, you get a running total of your calculations as they happen in a little window under the main one. It’s like a paper trail, but done elegantly. The percentage key is actually integrated into the calculation, in other words you type 23-5% and hit equals and you get the answer and the sub-result of what 5% of 23 is. Brilliant if you’re numerically challenged like…er…you are.

For the more demanding user there’s also a set of advanced maths functions which can be accessed with a single swipe of the finger. This gives all those Pi, root, /x type stuff which is no help at all down the local supermarket, but keeps exam kids awake at night with terror or delight. The free version of the app sports a very unobtrusive ad at the top of the screen, but if you want to do the developer a favor, buy the ad-free version for $0.99/£0.60.

  • It also has memory keys! I use those a lot. Thanks!

  • Excellent ! Thank you !

  • I’ll be sure to install this when I get my next phone. My current cheap/obsolete model is a bit short on resources and this needs 14 MB which I don’t have spare.
