With the free hypnosis spiral for Android you get a hypnotists tool for your smartphone or tablet to relax your patients with the force of the spiral and get them into a trance.
Note that the hypnosis disc alone does not have the ability to hypnotize someone. It is a pure tool to relax as it is used by many physicians. To put someone under hypnosis an appropriate training is needed.
If you not have the knowledge to hypnotize someone you can easy use this app also for fun for example to prank your friends by telling them you could put someone in a trance with this rotating spiral animation.

The structure of this free Android app is quite simple and include only a rotating disc. Start the animation with a simple click. Use the volume buttons of your device to adjust the speed. To stop the rotation only another click on the display is needed.

I would be very happy about a positive review in the Google Play Store but note that this is just a animation of a rotating spiral. Use it for relaxion! It requires to be able to hypnotize someone the necessary expertise for it. This is somewhere else to learn and not part of this Android-App.
