The app crashes almost every time I open it but, it does do what it's supposed to do and is super awesome! (When it works lol) I am using an iPod 4th generation if that has anything to do with the app crashing. If so, please fix if possible! ;D

This app crashes frequently (I'm on an iPhone 4S) and loses all of your work. If you don't remember to stop working and exit the current chart to go back to main menu every few minutes, then you lose all of your work. For number crunchers, this is a tragic and aggravating theft of valuable time and effort. Also, you cannot edit the right hand number field but rather if you even click on it it deletes whatever value was in there so you can't see what number was just in it. This is frustrating even when you intended to click on it to change it but it is especially damaging if your finger happens to accidentally touch the right side of the screen.

Many recent one star reviews seem to be by people of questionable intelligence. I've saved plenty of graphs in the app and many with lots of data. Nice little app that does work most of the time. No charting app I have looked is as easy to use as this. In app purchase works well. The only really big downside is that you can't superimpose one chart on another for comparison. If it had that capability and was 100% stable instead of 95% then it would be a 5 star app.

This app is great! It allows you to create and save your own charts and graphs. You can chose from different styles, and you can chose the different colors and values. It saves all your charts and graphs too. This is an awesome app, and it is incredibly easy to use.
