### 5/5 — Good Functional Calculator

*2026-01-29*

No fancy frills but it’s solid and intuitive. I find the add banner at the bottom much less intrusive than the splash screen some other calculators use.

### 4/5 — Almost perfect

*2024-02-27*

I would ask for a few improvements, but overall a great app!

It would be great to pay for ad removal!

I would ask to have the hex value show a “0x” prefix, and maybe a “0b” prefix on binary.

Also to allow switching bases by tapping the associated row, in addition to the dedicated buttons.

Also, maybe a bug, but it would be nice if it allowed entering and showing leading zeroes.  Currently it shows an error and question mark if you enter a leading zero.

Possibly would work better if you could predefine a bit depth and always show the leading zeroes for that depth, like 64bit, 32bit, 16bit, 8bit.  And it would truncate at that depth

**Developer response:** Thanks for the feedback!!! We will think about improving the application!

### 5/5 — Multiple base numbers

*2022-05-19*

I deal with an application that used base 20 in addition to hexadecimal (base 16).  This calc app easly does the conversion. Best calculator app that I have seen.

**Developer response:** Thanks for the feedback!!!

### 5/5 — Unbelievable converter

*2020-09-08*

Good working tool. I need to make hybrid calculations, Hex+Dec=Bin. It does it without deleting inputs unlike other calculator I use. The unbelievable option is kept in the converter. We can change number systems up to... base 30 and convert between unusual numeral systems!!! Not Oct and not Hex but 30, Trigesimal!!! The only drawback is, the buttons are too tiny. They should be bigger for comfort of work.

**Developer response:** Thanks for your feedback. We will definitely improve the design.

### 1/5 — Very poor prog calculator

*2019-12-13*

I was not able to find any and, or, xor, shift functions. Yes I can do math in base 9 or base 17 but none of that is useful. If you want to make a decent prog calculator at least support the fundamental logic functions used by programmers.

**Developer response:** Thank you for your feedback - it helps us improve the app! We will add this functionality soon.
