About this app

FloodAlert offers you all current water levels and forecasts in one app. It warns you reliably about emergencies as soon as a water level reaches a critical state. This way you can act early to dangerous situations like floods and take preventive measures.
The rain gauge app supports you in setting thresholds for different water levels with official limit values for relevant water bodies in Europe and the USA.

Rain Alert & Water levels from over 30,000 measuring points
The number of measuring points is directly related to the quality of our forecasts about future water levels and the quality of information about the current water level. Our large number of measurement points allows us to give timely emergency alerts and warnings about critical flood levels. Our Flood emergency app gives you a timely emergency warning and protects you against disasters.

Notification when your relevant water levels exceed your warning limit.
Warnings in our Rain Gauge & emergency alerts app can be easily set per gauging station. By setting the warning limit for river & flood levels, an alarm signal is sent when the water level exceeds or falls below an individually defined threshold level. This allows you to act early to emergencies such as rain & flood disasters.

Alerting by tones, vibration, screen output and LED flashing light
You can configure your warning signal individually. Choose the alert signal that is most likely to alert you to flood disasters and upcoming emergencies. The alerts of the Rain Gauge & emergency app will help you to prepare for disasters caused by rain or storms.

Catalog of measures and flood notebook
Especially with upcoming flood disasters & emergencies it is important to react quickly and correctly. Our action catalog is a step-by-step guide that helps you to react at the first warning of a critical water level. So our emergency alert app is the perfect tool not only for warnings but also for concrete actions.

FloodAlert Pro Features
- Prediction of water levels & tide gauges at selected stations
- Unlimited monitoring of water levels at all available measuring stations
- Individual alerting by own alarm tone directly in our emergency alert app
- Historical river water levels and gauges of water bodies.

Its a neat app, but it doesn't search well. I used the gps to find where I am, then did a search of a nearby town and it insisted on going to europe. Then I tried it again and it took me to california. Its just one town over but it chose the longest possible distance. It would make a lot more sense if it used my gps location as the center point to look for other towns. Then after I did a physical search and went back to my location, tall the sites were missing. If I hit the back key I was back in the normal map which makes no sense since there was no indication I was someplace else. Also I would like to know what normal is. I'm seeing rising and falling but without seeing what normal is its meaningless. Also there is no key what the colors mean. I understand red, but not the others. Another thing I really don't like is that warning. You only have that one really loud beep that sounds just like a fire alarm, and could go off in the middle of the movie or library without a good way to shut it up. It was actually deafening. And the only way to change it, even to your own thing is to buy it. On the plus side they include a volume control but you can't turn it off. Even on low its loud. But not as piercing as 100% default. You can see out of date markers, but they don't tell you what the date is. Same with the others, i'd like to know by the minute when this occurred. I'd like to be able to reverse how the date is displayed, it took me a bit to figure out it was backwards.

Hi Mike, I am very thankful for the time you took to give us feedback. We went through all of your points and could already fix some issues like the GPS starting point. The app update is already available. I only have 350 characters to answer here. If you write me an email, I'll answer all of your answers e.g. meaning of colors, volume... Johannes

The app seems pretty good although I've not had chance to test the alert notifications just yet. I suppose only then will I know how useful the app is. One thing that is annoying is it's very easy to accidentally alter the alert thresholds. I wish there was a way to lock them once they are set. Would give 5 stars if this functionality gets incorporated. UPDATE: No lock for alert levels despite this being promised months ago. Reducing to 2 stars due to lack of support.

Hi Darren, thanks for your feedback and update. We are very sorry but we only promised to implement threshold-locking and do A/B tests with it. We did that and the major feedback was that people complained about the extra step of "unlocking". So we reverted the feature and need to think of another solution. Sorry again, Johannes

this is a great app if you need as early warning for flooding. just go to your nearest River gauge and set your own early warning. the alarms in the premium app are excellent and is worth the purchase. you do have to be connected to Wi-Fi or mobile data to get the alarms...SMS is currently not integrated but is on a separate web version....well done guys for creating a great app for communities.
