## Most critical reviews (10 lowest-rated)

### 1/5 — No scientific calculator?????

*2016-09-02, version 3.5*

You are making it the worst one V3.6 you can't select numbers from history and there is
No scientific calculator 
I like the previous version can't change it to scientific calculator!!!!

### 1/5 — Error

*2016-07-06*

Show ERROR in result when you arithmetic many numbers without equals. Also, long string is not visible in full. And, you can't get back to any result in history - you need start everything over. Useless.

### 1/5 — No scientific function

*2016-04-18, version 3.3*

In the description this app compares itself to a graphing calculator, but I can't find any way to have it perform anything more than simple addition and multiplication: no log, no exponents, not even any trigonometric functions. This calculator just doesn't do anything useful.

### 2/5 — Won’t delete my history

*2020-12-20*

Annoying bug where no matter what I do, my last equation stays up. Really annoying for widgets

### 2/5 — Was awesome.

*2018-12-09, version 4.0.6*

The history used to save all of my previous calculations, which was super helpful. 
Now it doesn’t. Don’t know why. Frustrating.

### 2/5 — Not good

*2016-04-18*

This would have been good if it gives you the right answer but a simple calculation is bad,so would NOT recommend this specially if your a machinist. Example 2.756 -.551 and it gives you an ans. of 2.2 instead of 2.205

### 2/5 — Decimals

*2016-04-18*

I can't make an operation with decimals like 8 x 0.1 because the app fails.

### 3/5 — Nice, simple but....

*2016-04-17*

It needs a clear all button right now the (C) just delete one number at a time

### 4/5 — Good App

*2016-05-27*

The implementation of parentheses puts this app ahead of almost all other math apps. The only limitation- only 2 significant digits after the decimal point.

### 4/5 — Great for longer operations, simple enough for everyday

*2016-04-16*

The default iOS calculator is practical but the lack of history makes it less useful. I use it a lot when calculating my weekly budget. There probably better apps for that but this works great and I don't need any more complexity. 

It could use a bit more features like being able to export calculations to notes and email. If it had that I would have given it 5 stars.

### 5/5 — Works like it should

*2017-12-12*

Great developer support. App works good on the iPad, which is missing a stock calculator.

**Developer response:** We've rolled out a fix to this problem. Should be able to work now. If you encounter any other issues, please reach out and we'll help you resolve it.

### 5/5 — Simple but good

*2016-04-18*

I love this app it's awesome. I like the fact you can delete your history with just a swipe at a time. Wish the (c)button would delete all but it only deletes one number at a time.

### 5/5 — Great and easy to use app

*2015-04-28*

Finally an app with the history. Nothing compared with a default one.
