## What is CoCoRaHS Observer?

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 www.appcay.com.

### 3/5 — No longer accepts submission

*2024-08-27*

It’s much more convenient having an app and having to drag out the desktop to enter my data. But starting this week, it’s refusing to accept my submission. I tried deleting and reinstalling, but it still won’t let me enter my data. Very annoying!

### 4/5 — Very useful app for CoCoRaHS volunteers

*2024-04-20, version 1.3.2*

I am a current CoCoRaHS volunteers, and this app (along with the website) is very useful. (Also, I love CoCoRaHS.)

### 1/5 — Trashy App CoCoRaHS

*2024-03-11, version 1.3.2*

App doesn’t work! Can’t sign up, can’t log in. Crazy

### 1/5 — Worthless…

*2024-03-04*

Must create account to use… can’t create account… super rudimentary anyway, which is fine, don’t need anything fancy but would still like to be able to use.  To the developer: why bother?

### 2/5 — Convenient

*2023-05-31, version 1.3.2*

Gets the job done! Much more convenient than logging into the website each morning. Works perfect.

### 4/5 — Odd color choices

*2023-01-18*

Not sure why this isn’t a simple black and white UI and inverse for dark mode, but that would be nice. Convenient for quickly entering the daily measurement, but would be nice if it was easier for my homeschoolers to read. Light gray on sky blue for the bottom tabs is horrible on the eyes.

### 3/5 — Quirks

*2022-11-12*

In order to log totals I find you need to change the time of observation otherwise the preset time won’t allow the app to log the observation. Also very recently there’s an issue with logging into the app. It claims the password/username are invalid.

### 3/5 — Convenient but could use some UI fixes

*2022-10-13*

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.

### 1/5 — Review not posted

*2022-09-12, version 1.3.2*

Submitted review earlier and NOT POSTED!

### 3/5 — Can’t change time; no link to significant weather report?

*2022-08-08*

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.
