### 5/5 — Best calculator on App Store!

*2014-02-23*

This must surely be the best on the App Store. It has a clever yet intuitive user interface and functionality that goes well beyond what others offer - including even unit type conversions. Highly recommended!

### 5/5 — Excellent programming calculator!

*2013-01-28*

Title says it all. Feature rich and yet easy to use.

### 4/5 — Good but crashes

*2012-04-20*

Really a good calculator, but almost every time I turn it on it crashes. I have learned to enter a number and press a function key to crash it then it is good to go. You can run any number of calculations after it crashes. It just has to get the crash out of the way. 
I use it every day and love the conversions.

### 1/5 — Not Happy

*2012-02-17*

This program crashes frequently.

### 5/5 — Great calculator - like all the conversions

*2011-11-01*

I'm not sure why the last reviewer couldn't do their Algebra 2 homework. I found the calculator had everything I needed for undergraduate and graduate level Bioengineering classes. I like that it keeps track of the order of operations as you go, and I especially like the conversions portion of the calculator, which I'm able to use for physics and chemistry calculations. The calculator is also nice and easy to use when I make price comparisons in the store as well. I highly recommend it.

### 1/5 — mediocre

*2011-05-02*

Just downloaded.  Doesn't come with an information page or manual.  Can't seem to find how to turn the annoying click sound down or off.  The memory store function does not seem to work, this is a major flaw, there is absolutely no point in having a scientific calculator if you can't store any numbers.

Don't buy it unless these things are resolved.

Also no stored value of pi???

### 1/5 — Badddd

*2010-09-08*

Good for very simple math but I can't even get done with my algebra 2 homework using this waste of 10 dollars try a diff calculator before this one

### 5/5 — Speedy Conversions + Intuitive functions -- Makes my iPhone even more indispensable!

*2009-07-26*

I don't tote a calculator around, but more and more, I find myself wishing I did. However, I don't make a move without my iPhone. The "Calculator" app has been a great find, well worth the cost. Unlike the built-in packaged iPhone calc, this application includes a wide variety of pre-made conversions. Volume, Area, Length, Mass and Logic functions each receive their own screen of keys at just a touch of a button. This app uses gestures that make more modern, fluid sense for those of us used to Macs and Windows functionality. I've had to unlearn some old-school calculator habits because of its more modern, intuitive procedures. I appreciate this app, it has given me one more reason to regard my iPhone as one all-encompassing, powerful tool.

### 1/5 — This calculator is the worse ever! A terrible waste of money

*2009-06-22*

You cannot write in algebra mode! Is the same as the standar calculator of the os of the iPhone!

### 5/5 — Awesome Calc

*2009-04-18*

Mike W is the best programmer I've ever met. This calc is destined to be Apple standard.  I'm excited for his 3.0 version.
