Franz Bruckhoff has Flowing – Meditation & Mindfulness App for the iPhone, iPod Touch, iPad in the App Store for FREE (regularly $1.99) for a limited time.

Upgrade your sleep, focus & productivity with Flowing, the third sequel to popular Best of 2014 app Windy.

Imagine you could sleep outside in nature instead and enjoy the sights and sounds of wonderful streams, waterfalls & rivers recorded in psychoacoustic 3D for headphones. As if you were there. And if you felt like it, imagine you could mix in some extra 3D nature sounds such as rain on a tent or birds in the trees around you. Get the great sleep you deserve.

Flowing integrates deeply with my other apps Windy, Sunny and Away and is compatible with Thunderspace and Sleepy Fan. Over 4,000,000 people have enjoyed them so far. Many use them to sleep better, to meditate, or to focus on their work or studies. Some use them to help their kids sleep. And I believe Flowing is a fantastic addition.

Flowing’s natural streaming water delivers a versatile white noise ambience that drowns out the noise around you.
