EMDR Therapy (Eye Movement Desensitization and Reprocessing) is a niche therapy used for treating PTSD and relatively unknown outside this circle. However, it has the potential to be used for other conditions like anxiety, panic disorders, sleeping aid, pain management and phobias which is the ultimate goal of this app.
Current apps for anxiety use CBT (cognitive behavioral therapy), meditation or breathing techniques. However, these methods necessitate conscious effort from users, EMDR doesn't need much homework.
If you have, for example, intrusive thoughts, don't try to suppress them, let the thoughts flow and use at the same time the bilateral stimulation features (visual, auditive or touch) implemented in this app. The bilateral stimulation will damp the intensity of the thoughts and speed up the reprocessing of those memories so that they will occur less frequency and intensity over time.
