Pocket Storm is an environmental audio player which streams an hour-long, ever-changing thunderstorm.

It starts with a calm summer night. Soon you’ll hear thunder in the distance, then wind and a spatter of rain. After half an hour you’ll be in the thick of the storm. By the end of the hour it will have faded into the night again. Then the cycle begins again.

Pocket Storm is not like other environmental audio apps. Every thunderstorm is different! Wind, rain, thunder — even chirping crickets — every sound is chosen from a library, with subtle variations of pitch and timing. The Pocket Storm weaves these elements into a tapestry of sound which will never repeat.

- A storm that approaches, surrounds you, and then drifts away.
- Elegant, uncluttered interface.
- Set the storm’s duration anywhere from a sixty-minute monster down to a five-minute squall...
  ...or hold the skies in place, and listen to the same weather for as long as you want.
- Listen with headphones...
  ...or send audio to an AppleTV or other AirPlay device on your wireless network.
- Runs as a background audio app.
- Never-ending, ever-changing soundscape generated right on your iOS device.
  ...(No Internet connection required!)

Pocket Storm is also available for your new Apple TV. It's a joint iOS/tvOS purchase – buy either version and you can download both!

All the sounds in Pocket Storm's library are Creative Commons licensed audio samples from

Use the Pocket Storm for white noise, tuning out distractions; for relaxation, meditation, or going to sleep. Tune your desert to rain, or your city street to chirping crickets.

Love this!



A Thunderstorm in Your Pocket

I've been beta-testing this, and, what can I say other than: I won't go to sleep without it. The app provides a number of useful options to adjust how the thunderstorm progresses. You can vary the speed at which the storm crests and abates, and you can have it play forever, or stop after a certain number of minutes, or – my favorite mode when using it at bedtime – have it stop playing when the storm is over.

It's a beautiful little app that does only one thing, and does it exceedingly well. If the idea of having a wonderful, never-ending thunderstorm to listen to whenever you want appeals to you, you need this in your life.

Excellent App!

I have had this app for a couple of weeks now and I think it is a great concept and it works flawlessly on my iphone. It doesn't just play a prerecorded soundtrack, but rather dynamically mixes various sounds to create a unique thunderstorm each time. The creature sounds (crickets, frogs) that you hear during the "calm" cycle are also terrific. I highly recommend this app if you are looking for a one-of-a-kind ambient sound experience. My highest compliments to the author.

I would love to see a future app or option that has rainforest/bird creature sounds.
