If you missed yesterday’s roundup of the best paid iPhone and iPad apps on sale for free, definitely go back and check it out. There are still a few freebies left in there, including an app that will help you stop all those annoying spam calls you get! We’ve rounded up seven fresh iOS apps on sale for free on Tuesday though, and they represent the best of the hundreds of premium apps that were discounted today. Hurry up and download them for free before it’s too late!

This post covers paid iPhone and iPad apps that have been made available for free for a limited time by their developers. BGR is not affiliated with any app developers. There is no way to tell how long they will be free. These sales could end an hour from now or a week from now — obviously, the only thing we can guarantee is that they were free at the time this post was written. If you click on a link and see a price listed next to an app instead of the word “get,” it is no longer free. The sale has ended. If you download the app anyway, you will be charged by Apple. Some apps may have additional in-app purchases. Subscribe to our RSS feed to be notified as soon as these posts are published and you’ll avoid missing the sales we cover.

Thunderspace ~ Rain & Thunder

Normally $2.99.

During the day, Thunderspace won’t let you focus on all the noise around you. And at night it will make you very sleepy. Do not use while operating a machine, vehicle or star destroyer.
******

We can’t calm the storm. But the storm can calm us.

Join us, over 1,000,000 relaxed Ladies and Gentlemen who immerse ourselves in realistic thunderstorms any time we wish to relax, focus, sleep or meditate.

Join the Thunderspace revolution and experience the great benefits Thunderspace will bring to your busy life.

Thunderspace’s spectacular 3D audio sound field reproduction technology delivers a realistic, high-quality open space sonic ambience over regular stereo headphones. How so? Think 3D glasses for 3D film. Left eye, right eye. Your brain combines these two images into a 3D image. The same principle works for sound: Left ear, right ear. Thunderspace audio is biomimetic: It reproduces the ambient sound field exactly the way you hear. As if you were there. With interaural time and level differences. The storm rumbles high above you, and the rain falls around you. Once you experience the transportive sonic ambience, you will never again want to go back to simple stereo.

Precisely synchronized lightning flashes, frequent updates with new premium quality thunderstorms, a carefully crafted user interface, and highest quality recordings from Emmy-award winning nature sound recordist Gordon Hempton separate Thunderspace from all other relaxation apps.

Thunderspace teleports your mind to a place far away from stress. Far away from the noise. So you can focus on your work, sleep better and relax.

All audio in Thunderspace is of Taptanium-certified quality. Absolutely no human-made noise, no cars, no airplanes, nothing. Just highest quality nature audio.
