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.

This calculator only does sample standard deviation. (n-1 in the denominator) It should be labeled as such in both the title and the data output

Okay, I never write reviews but this app I think has changed my life and the fact that it is free makes it 100 times better. I doesn't just do standard deviation but so much more! I would recommend this to anyone with a lot of math that they don't want to do by hand

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.

Keeps Crashing
Every time I go back to edit or delete a number/item the app closes forcing me to start over. Very inconvenient. If it that didn't happen I'd give the app 5 stars.

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
