raincast radar screen stepping from observed rain to the 20-minute forecast

This is the actual app, on a real rainy morning

Live radar over your map, a timeline of the next hour in 5-minute steps, and a slider that runs from what just happened to what's about to. The animation you're watching is the real forecast stepping from now to +20 minutes — no mock-ups.

  • Your places, not "Dublin". Home, work, the pitch — up to five locations, each with its own warning time and sensitivity.
  • Follows you when you're out. Switch on "My position" and the warnings track your phone — shopping, cycling, anywhere we cover.
  • Quiet when you sleep. Each location has notify hours and weekdays; overnight rain shows in your history instead of waking you.
  • You mark what really happened. Thumbs on every alert — your verdicts train the next, smarter forecast model.

We state plainly where we operate. A place outside every live area gets an honest "not in your area yet" and a waitlist spot — never an empty map.

How it works, in three steps

1 · Read the radar

A new Met Éireann sweep every 5 minutes, cleaned of ground clutter and RF interference spokes.

2 · Track the motion

Optical flow between frames gives every cell a speed and heading; we move the rain forward 60 minutes.

3 · Your spot, one sentence

Sample the forecast at your exact point: when it starts, how hard, how long — and a push alert before it lands.
