🏷️ About: NerdCalc is a binary, hexadecimal and decimal calculator that displays all three number bases at the same time. With NerdCalc, you can quickly switch which base you are inputting and the result of your calculations is always updated for all three bases, no matter what the current input mode.
- Quick and efficient for testing low level bit operations
- Simple and easy to use interface
- Calculates binary, hexadecimal, and decimal values simultaneously
- Helpful for subnetting in Cisco networking classes
- Useful for converting 2's complement for MCU coding

I don't know what is nerdier: knowing how to use all the functions or wishing you knew. I'm in the second group, but can highly recommend NerdCalc.
UPDATE: I am now deleting because NerdCalc update requires iOS 5.

The 2's complement function does not work. It boots me off when I try and input anything in 2's complement mode

Latest "upgrade" includes the ever popular annoying ads "feature". Deleted and replaced with Pro Calc.

Extremely intuitive user interface. Rich functionality. I especially like the ability to do bit manipulations like Shift, And, Or, XOR. Nice design!!!!!

My goodness, I’ve used it maybe ten times so far in two days, and it asks me for a review every time. I’m just writing this to shut it up, gosh dang, wow.

Useful and simple.

I'm a graphic designer and I've been using NerdCalc for color calculations. This was 99 cents well spent!

On a low-level embedded system programming job, this calculator was really useful for converting binary inputs to hex, and general binary math. The background's a bit loud, but the functionality is good!

The perfect app when you have to quickly test the results from low level bit operations. When I'm testing the values stored in my company's driver registers NerdCalc is a huge time saver.

I needed to mask fields out of a hex number then get them in decimal. NerdCalc was as close to perfect as I could expect.
There IS something amiss with 2's-comp -- sometimes it crashes, mostly it works fine.

Update:
Great app and great dev who listens to users - 5 stars.
Previous review:
Anyway, I have to give this one star for not being compatible with, at least, 4.3 when it and just about every app out there *should* be. I'll change my rating when this "bug" is fixed. Thanks.

I am needing a tool to convert 2’s complement for MCU coding , I found this tool!

Needed a calculator to help me practice subnetting for my Cisco networking classes. This calculator certainly does the trick! Thanks!

Used this today in a training class for a major vehicle manufacturer. Simple and easy to use.

I've download several calculators and this is by far the best. The interface is simple and easy to understand. I really like how it calculates binary, hexadecimal and decimal values all at the same time. It's a steal for .99 cents and a must have for anyone who crunches serious numbers.
