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.

This application is provided by Steve Woodruff and Appcay Software, not CoCoRaHS. Questions, comments, and issues can be reported to us at

Convenient but could use some UI fixes

It’s much more convenient having an app for reporting rather than having to log into a desktop. I appreciate the font color fix. A few other usability improvements that I would love to see:
— Add functionality for severe weather reports on the app.
— the “additional notes” should be a comment field rather than a single line, so you can see what you’re typing.
—after inputting observation data, if you go to the additional information page and then come back, the observation data is deleted. I’ve also noticed this happening previously on the notes side as well, but it looks like that may have been fixed.

Can’t change time; no link to significant weather report?

New observer here. I see from previous reviews that my issue is not new. The app takes me to the current time I want to enter, but when clicking “done,” nothing is changed.

Also unless I am missing it, there is no quick way to get to the significant weather report form. However there is a link to the website to do both of these things; just takes longer.

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.
