Nice app, screenshots misleading

The screenshots in the App Store for version 2.2 refer to graphs that appear with x axis min value 0 and max value 1, listed as 0, -5, 5, 1. I suggest zooming out for the screenshot so that it shows the correctly graphed values (-10, -5, 5, 10). I almost didn’t download the app because it seemed so fundamentally flawed in the screenshots. Once I did download, I see that it graphed correctly. Nice app.

Thank you for your review!
The values are actually correct in the App Store screenshots, it’s just that they are cropped. (-1)0 to the left and 1(0) to the right - still, it does look a bit confusing! :)
Have a great day!

Very good app

This app is very useful and the layout is super simple and easy to use. Although it would really help if you could make use of multiple variables. Maybe this could be made possible in a future update.

I don't do thismuch

Great App One Flaw

Overall this is a great calculator that I would definitely recommend, especially because it’s free! As another reviewer said I liked it so much that I deleted the default one. The only flaw is that the shake to undo is finicky at best. Other than that, amazing app!

Thank you for your review! 😊

I believe the shake to undo issues you were seeing got fixed in the 2.6 update. If not please reach out via the app.
