This app lets you perform all kinds of arithmetic and logical operations on numbers. These operations are : +, -, *, /, %, AND, OR, XOR, NOT, LSH, RSH. You can read in detail about the features of this app here.

  There are several apps on Google Play which have the same name or which perform similar functions. But this app is unique is some aspects. These are –

  • All functions can be performed on the same screen without swiping left/right. This saves a lot of time.
  • It converts a number to other number systems and displays them on the top of the screen while the users inputs the number. This lets the user view the values of a number in all number systems at the same time.
  • Some calculator apps use a different layout for each number system which may distract the user. This app uses the same layout for all number system and groups of buttons are enabled/disabled as per requirement. For example, if you’re working with a hexadecimal number, all number buttons i.e. from 0 to F are enabled. If you’re working with binary numbers, only 0 and 1 are enabled, and so on.
  • You can change the theme of the app as per your preference (light/dark).



  Every app, no matter how well-designed it is, needs improvement. The same is true for this app as well. This app has a lot of scope for improvement. In future versions of this app, I am going to add more features and fix bugs (if any bugs are found by users). I want to make it the best Programmer’s Calculator app on Google Play. Therefore, I would appreciate it if you provide constructive feedback after installing and using this app. Your feedback would help me improve this app. Thanks in advance. 🙂
