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.

Last update ruined the graphics (fixed) now input borked

A graphics glitch that rendered the app useless was fixed within days. Well done. It does what it’s supposed to - send station data to the servers. There are still minor improvements that could be made such as make “0” the default entry for amount.

Don’t they test this app before releasing? The glitches are awful and obvious.

On the iPad, when I enter a precip total then go to details to enter snow data, my precip value disappears when I go back to the first screen. Also, can’t edit input on the iPad, have to do that via the web interface. This is all new since the most recent update.
It’s certainly handy to have this app so I enter data in a timely manner, but bugs need to be addressed.
