CoCoRaHS Observer for Android is an application that lets registered volunteer Observers submit their daily precipitation reports via their Android 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.

Snow amounts? This App would be much better if when I enter my data, it shows as if I am reporting on snow amounts! I live in the US Virgin Islands, the Caribbean, for goodness sake!!! I cannot report rain!

Michael Nye

HTC DNA The best thing about this app is one can enter the results right at the rain gauge.

Nate Outland

Love the app! But... It would be nice to be able to input multiple observations in one day, for morning and evening rains. It would also be cool to be able to check the log of past observations without entering an observation.

Eric Tew

Can't login. It causes an error and cuts off.

David Pearson

Nice app Works good. Can you add a trace snow check box next to trace precip?

Brent Sigler

Nice app Handy for daily observation reports.

Cheri Alford

Very Convenient Love being able to record my reading from the app right away.

John Hornby

Makes reporting very convenient This app is a game changer for Cocorahs by making the reporting possible on the spot and on time!

Andrew Ervin

Easy reporting For mobile users who are cocorahs observers, this makes life easy

Ted Morell

MO-WT-13 Great app, thanks!

elijah felling

It is a good app but I did not give it a 5 star rating because it would be nice to be able to do a muti day accumulation.

Susan L

Wish there was more navigation choices and wish message of the day would size for phone window.

Kevin Miller

The website is better and also supports metric I have a 10" tablet. The CoCoRaHS website is easier to use than this app, it allows me to input and report in metric (cm & mm) -- which the app doesn't, and it has far more functionality than the app. So why wouldn't I uninstall the app?

Paul Reape

Great tool. I shouldn't say about time, good things take time, would be cool to see maps, but this works.

Doug Jones

Finally I have been waiting for this for awhile now. Awesome!!!!!

John Winter

Great Perfect for reporting on the way out

Stan Scott

Great, just add county maps.

Karyl Lipson

Good for dailies Is there a way to submit a multi day report?

Steve May

Makes Reporting Simple Perfect app for this CoCoRaHS.

Trent Bosler

Awesome app! Use it everyday! Very reliable! Thanks for updating for me! It makes the app complete for me!

Jerold Pence

Big Time Saver! Measuring precip and reporting from my phone standing next to my gauge. SWEET!

Allen Metcalf

Works great problem solved Doesn't work on the galaxy s4. I just see html code on the blue screen with the icon. Really wish it would work.

R. Gregory Rushing

Nice and Easy Does what we need to report. Wish we could get a full app with maps etc, but this is a volunteer organization after all.

Tom Pavlak

Stiil needs help... Sprint customers like me can only submit if connected to wifi...not 3g. Would really like to submit monthly zeros...see maps etc. Good job so far..update. still no updates to program. Still have to wait for wifi. While the intent is great the execution is not

Rob Marley

Now works perfectly Originally I couldnt get this to work on my Galaxy S3, but the latest update works perfectly. Thanks to the devs for making it work for me! Simple, quick and easy reporting. I love it!

Ed Maff

Samsung Galaxy s3 Please add support for evapotranspiration data.

Mike White

Cool Just what the doctor ordered. Clean and Simple. Thank you.

A Google User

Doesn't workDoesn't I just get the HTML code on the report page on the Kyocera 3g phone.

George Bridgers

Outstanding App Thanks for building this app. It does the trick each morning for submitting the daily precip report without having to access the CoCoRaHS website.

Courtney Smith

Exactly what I needed. Exactly what I needed. Makes data entry quick and easy while standing at the gauge.

A Google User

I love it This makes entering the data much easier.

A Google User

Perfect! I now grant my five stars! great job perfecting this great time saving app. Helps me submit my precip report right from the guage. Thank you from NY-SL-10. St. Lawrence county NY. Coordinator.

A Google User

Love it It's so nice to imput my data while standing at the weather station in leiu of trying to remember it when distracted. Thank you so much.

A Google User

Thank you! I asked for this well over a year ago, and was told that it was on the list, but it's great that a community member went ahead and developed it. I have a few suggestions for improvements that were e-mailed to the developer, so hopefully 1.0.4 has those improvements.

A Google User

It's a good start Only complaint is that the Login button is hidden by keyboard until back button is pressed. Maybe that's something that seasoned Android users know.

Stephen Clay McGehee

Much more consistent reporting Does what it needs to do and does it well. Much more convenient reporting right from the rain gauge. My only complaint is that I can't view my past reports unless I am entering a new report. Being able to show other folks what we're doing would get them interested in joining cocorahs. Please consider adding that capability! Thanks for a great app.

Tom Gunter

Great app with HISTORY function This is a great way to make reports. For those who can't find the HISTORY, press and hold the button for switching apps until the menu appears, then tap History. (That's your Android top of the day. It works in other apps, too! Even the Play Store. Try it!)

David Pearson

Works great, change snow entry Can you add the snow entry box to the initial screen that comes up? Also a check box for trace of snow just like precipitation.? Also why can't we edit previously sent reports? When I try I get an error.

Robert Jordan

Very good design and functionality to allow basic reporting. If you plan to add more features, display of historic data without first making an entry and maybe a map showing the current day's reports.

Paul Stallings

Dislike update One now has to exit app to enter in multiple days. What happened to the menu button??


In the short time that I have been using this app I can say that it is very consistent and accurate. I hope that additional features will come along, like adding a Menu, or additional screen, for a link to show the Observer Report History page. Otherwise it definitely does what it is designed to do. Thanks!

Michael H

Great little app Does what needs to do,cool to be able post the info from your cell phone......

Brandon Clowers

Edit Csnt edit report if entered incorrectly but other than that great app. No link for forgotten username or password which ive done

Tammy Webb

Awesome Love the app and those who make the coco program possible

Abc Abc

Works. Simple Good clean interface that does the basics.

Andrew Ervin

Trace of snow not allowed The update continues to have problems letting observers put in a T for snow. The app only allows numerical values. Please fix this

Mike Dvorak

Great but new problem When I open it on the login screen, it just hangs and says "Fetching History". I can't do anything and I don't see how it could be fetching anything since I'm not logged in.
