This app changed my life for good

This app does wonders. I'm a new person. Before this app I was failing my math class but now I'm making a 99.99. 10/10 would recommend

Need to fix

How do you delete a row? Can not add past 19 numbers.

Incorrect Median

Incorrect data output. Very disappointed I will not get my 99 cents back

Unable to scroll down

This doesn't allow for 10 numbers and unable to scroll down and make row corrections. Sorry I paid the extra for the locked features.

No negative numbers

Doesn't work

Bad

Does not let me scroll down to add more. 1 star boiii

Value entries flawed on iPhone

The app does what it is suppose to. Works ok on iPad. However, the publisher needs to fix the value entry aspect on the iPhone as you cannot see anything past about eight entries. It will also ask you to "delete a row" but has no explanation on how to do this (can't delete what you can't scroll down to see). Row deletion seems to be a common problem no matter if it is on the iPad or the iPhone. A fix for this would be warranted.

Needs Work

Standard Deviation and Mean values have been mixed up, by the look of it.

Incorrect labels

You have the labels for mean and standard deviation swapped.

Best app ever!!

I don't know how I ever lived without it!
