Review of Android Calculators.

The quick recommendation: DarkCalc and Cyanogenmod both have the option of a basic or scientific calculator view with large text and which are Talkback accessible.

 

The longer answer:

A calculator is one tool which is quite handy to have and which everyone has their own ideas on what they need from one.  Most devices come with a calculator app but some are better than others for large print and Talkback accessibility so I’ve rounded up all the ones I could easily find on the Play Store which don’t need Internet access and put them through their paces.  I’ve put together a table of the main accessibility features of each sorted by (smallest) font size, and then listed each of the apps.

Summary:

There are a range of basic and scientific calculators available with large fonts and I quite like how in several such as Cyangenmod and DarkCalc you are initially presented with a basic view, but can swipe to the side to bring up extra optons which gives access to all the features without cluttering up the screen.

    • The ability to adjust colours looks good, though I must say, looking at the permissions, I wouldn’t use a calculator which needed access to my accounts – there is no need for that. I also think the desire for permission to connect to the Internet is well overused and again something a calculator doesn’t need, unless perhaps it lets you calculate conversion from one unit to another where that changes (eg currency). Thanks for sharing!
