Downpour
Real-Time Rain Simulation
Fall asleep to the most realistic rain simulation on the App Store — rendered live on your device, not a looping video.
Downpour isn't a playlist of rain recordings over a stock photo. It's a real-time rain simulation powered by your device's GPU — every raindrop rendered live, reacting to wind, gusts, and intensity in real time.
Set the mood. Dial in a light drizzle on a calm night or crank it to a full thunderstorm with howling wind and rolling thunder. Watch lightning illuminate thousands of falling drops, then let the rumble fade as you drift off.
What Makes Downpour Different
Every raindrop is simulated in real time — no pre-recorded loops, no static backgrounds. Adjust the wind and watch every drop respond instantly. This is rain you can feel.
