7 Best Water Apps

We are all connected to our mobile phones. When I say we, I mean the big we, like the 8 of every 10 people around the world that now have mobile phones. In some countries, more people have access to mobile phones than clean water.

Big data, wireless sensors, and mobile technologies provide the foundational ingredients to help manage our resources more efficiently. I wrote recently about an example close to home on the Savannah river, but there are other examples. In Liberia the public works ministry deployed mobile phones with an android powered app to help map all of its roughly 7,500 publicly accessible water points. This system, which has been used in other countries since 2010, was developed by two nonprofit organizations: Water For People and Akvo. In the following video Ned Breslin, CEO of Water for People, talks about this technology.

A couple years ago I tried a more humble quest to find 7 Water related Apps. Looking back at this post this morning, I laughed at myself. You know you have have to stretch a bit if you have to include the Dubai Electricity and Water Authority’s app. Out of those apps, none of them currently are on my iPhone.

I thought I would share an updated list of water related apps on my iPhone.  Maybe a few of these will still be on my phone in a couple of years.


  • MyRadar Pro Weather Radar ($1.99 ios/android) – Most weather apps have to much stuff. This one doesn’t. It is just doppler radar with a four day forecast. Simple.
  • Dark Sky ($3.99 ios) – I like this app for what it wants to be more then what it is now. It tries to predict when it will rain or snow at your exact location, and warn you ahead of time. Not quite perfect yet, but this is the future.

Real World Water Data.

  • Streamflow Plus ($2.99, ioS) – This app displays real-time stream height and flow data read from USGS river gaging sites. It displays current measurements and provides interactive charts plotting one, seven, 30 or 90 day views. You can also save your favorite USGS gage stations. My only concern is that I am hoping the developer keeps his interest in developing the app. It’s been over a year since an update.
  • River Data (Free, ioS) – This is similar to Streamflow Plus without any mapping features, however, you have more control over the data that is mapped. Simple and effective. You can also save your favorite USGS gage stations.
  • Buoys ($0.99, ioS) – Although I live 5 hours from the coast, I used this app during Hurricane Sandy to get buoy data. You can get swell direction, height, and interval with good-looking graphs.

Water Unit Conversion

  • Convex ($1.99, ioS) – If I need to convert units of flow beyond Cubic Feet per Second and Million Gallons Per Day, this is the app I go to. Intuitive, good-looking and easy to understand interface makes it cinch to use. Convex supports 979 units across 20 different categories.

Water Information on the go.

The future is wide-open for mobile applications.  Who knows? It may be cool to think that none of these apps will be around in the next two years.

Did I miss any worthy water apps?


    • Thanks Elizabeth. I’ll give it a try.

  1. I wonder if anyone but water geeks care about apps like these. I love the Water Footprint app. More people need to know how much water they really use.
