How it works

Accurate rain and snow data from radar observations

Precip measures what actually fell — not what a forecast predicted. No hardware to install, no gauges to check.

  • 1
    180+ Doppler radar stations and a quality-controlled network of rain gauges observe precipitation as it falls across the US and Canada.
  • 2
    Precip processes these observations into high-resolution estimates without gaps.
  • 3
    You get hourly totals at each of your saved locations, delivered in the app or via automated alerts.
Observations, not forecasts

60% more accurate than checking forecast history

Most apps show you yesterday's forecast as 'history.' Precip measures what actually fell using radar and gauges.

Precip covers the contiguous United States and Canada at high-resolution. Data is updated regularly and automatically refined as additional gauge reports become available. See our full data availability & specifications.
