Welcome to IEM Mobile! The preferred app to monitor
NWS Weather Alerts, NHC Feeds, and NWS Chat Live.

Use the IEMBOT Monitor to view specific NWS Offices
for products sent out, as they are sent out.

For more advanced users, NWS Chat Live is there for
joining specific NWS Rooms to communicate between
storm spotters, chasers, emergency management, and more.

We offer 2 versions of NWS Chat Live on the app. One version
is powered by the Iowa Environmental Mesonet of Iowa State University
and can be access by all users.

The other version of NWS Chat is powered by the National Weather Service
and can only be accessed by Emergency Officials, NWS Officials, officially
registered users through the National Weather Service.

You can also view Storm Prediction Center and National Hurricane Center
feeds through the app to view Mesoscale Discussions, Tornado and Severe
Thunderstorm Watches, Convective Outlooks, and Tropical Weather Outlooks.

Users will automatically recieve Push Notifications from the Storm Prediction
Center and National Hurricance Center if not opted-out of push notifications.

**NOTE: NWS Chat Live can work on the iPhones but will work better on the iPad and iPad Pro.

• Added the Official NWS Chat Live

We have now added the Official NWS Chat Live onto the app. So now Registered users like Emergency Officials, NWS Officials, or anyone that has access to the NWS Chat through the National Weather Service can take advantage of the new feature!

Good app!

Good app for monitoring EAS alerts. Will update 4 to 5 stars if overlapping text issue gets fixed.

Awesome app after latest upgrade.

THANK YOU for bringing this app to the stellar standards it was before the implementation of ads.

Navigation is WONDERFUL and I can get a lot of information from various sources with one app, the perfect design and functionality of this app.

Thanks again for removing the intrusive ads and resurrecting this app to what it was, an amazing app leading to valuable weather resources not found in other weather apps.

Developer Response ,

We are working on getting most of the ads removed. You may not know this but app development is not free whatsoever. So in order to keep this app up we have to run ads. We are currently working on some solutions and some changes to the UI. This will include forward and back buttons to navigate around the Product Viewer more accessible. Be looking out for that in the next upcoming updates. Also it only shows ads when you click on the "IEM Mobile" button. Not any of the products within the IEM Mobile screen. -BC

Finally! A dev who listens!

The planets mist have aligned, because an app developer actually listened to their audience. We asked for annoying advertisements to be removed, so that potential hazards can be seen firsthand, and you (the dev) responded! This should not be as shocking as it is, but in 2018, nobody really listens to anybody anymore. I cannot thank you enough for actually listening to us customers.

Developer Response ,

I need to listen to my audience. You guys are what makes this app popular! Of course I had to. The only reason it took so long is when I made V3 it was coded in Xcode Beta so it had the iOS 12 support but Apple was not allowing anything iOS 12 on the App Store yet. So I had to halt releasing it. But all the ads are gone and are not coming back! So I hope you enjoy the app and stay tuned for future updates!
