Every thunderstorm is different! Wind, rain, thunder - even chirping crickets - every sound is chosen from a library, with subtle variations of pitch and timing. Pocket Storm is not like other environmental audio apps. By the end of the hour it will have faded into the night again. After half an hour you’ll be in the thick of the storm. Soon you’ll hear thunder in the distance, then wind and a spatter of rain. Pocket Storm is an environmental audio player which streams an hour-long, ever-changing thunderstorm.
