Just saw another post on CoCoRaHS so I went to look at my entries. This app has a strange way of moving around the various screens and you can't use the backup button without getting a message asking if you want to exit or not. Have to use the lower-left button to get to another screen. Not very intuitive IMHO.
Also, the documentation says you can update your historical files. I am unable do that. When I bring up Report History, I see my entries but when I tap on any of the data, I only get the line highlighted and nothing else happens.
Am running version 1.1.4 for Android on a Samsung Galaxy S3.
