CoCoRaHS Observer for iOS is an application that lets registered volunteer Observers submit their daily precipitation reports via their mobile device. In addition, users can view past reports to ensure accuracy.

CoCoRaHS is an acronym for the Community Collaborative Rain, Hail and Snow Network. CoCoRaHS is a unique, non-profit, community-based network of volunteers of all ages and backgrounds working together to measure and map precipitation (rain, hail and snow). By using low-cost measurement tools, stressing training and education, and utilizing an interactive Web-site, their aim is to provide the highest quality data for natural resource, education and research applications. They have volunteer observers in all fifty states.

Works pretty well to report precip

In general, no complaints with this app. However, recently I started having an issue on my iPad (latest iOS) where the “Submit” button covers up the precip amount. So I have to guess that I’m inputting the correct amount because I can’t actually see it after I type in the numbers.

Please fix!!

After I enter my data the screen drops half way down the screen so I can not submit it (use the submit button) . This has been occurring over a month. I have reloaded the app and it still happens. I am using my iPad to submit entries
