Useful tool with a few improvement opportunities

I downloaded this tool to help with a time study I'm doing at work. I must say that the time study portion of the tool is very easy to use and very helpful.

My issue has been repeated app crashes on my iPhone 6S whenever I attempted to edit the data or attempt some of the graphs. If the app crashes are fixed then I would have rated the app much higher
