In case you haven’t already heard about Thunderspace, it is a fabulous little iOS app that replicates thunderstorms using 3D, stereoscopic virtual sounds that you listen to via your headphones. It is a great way to just sit back and relax. Now would be a good time to try the app, as it is current available Free on the App Store. It comes bundled with two thunderstorms and you can purchase additional ones using IAPs.
