What We Like
  • Detailed information via US Geological Survey.

  • Can track each flood stage level.

  • Free via ads.

What We Don't Like
  • iOS only.

  • Far from pretty to look at.

If you live near a body of water then Floodwatch is an essential app for you. It tracks all the rivers across the US courtesy of the US Geological Survey's real-time data, providing you with the most recent and accurate stream gauge data available.

It's possible to add favorite rivers for easy consultation. In each case, an arrow demonstrates if the water is rising or dissipating. Graphs further highlight how the water levels are changing in the past 24 hours as well as historical data on the past 7 days and more. 

Floodwatch isn't particularly stylish but it gives you fast insight into just how the water is rising near you, giving you a heads up on if the levels are unusually high so you know when to be concerned.
