Download of Flutter 2.10.3 for Mac was available from the developer's website when we last checked. We cannot confirm if there is a free download of this app available. The software lies within System Tools, more precisely Device Assistants.
We recommend checking the downloaded files with any free antivirus. The most popular versions of Flutter for Mac are 0.7, 0.5 and 0.1. This free application works fine with Mac OS X 10.6.6 or later. The actual developer of this free Mac application is Bot Square, Inc.
From the developer:
Flutter enables the use of hand gestures to control music and videos via the built-in webcam in your computer. We hated using the keyboard and mouse for controlling music in the background or watching movies on our computers from a few feet away. So we decided to solve this problem..
