Calmvalera Relax is an iPhone app developed by Hevert-Arzneimittel GmbH & Co. KG. This free app falls under the lifestyle category, specifically in the health and fitness subcategory.

Calmvalera Relax aims to influence thoughts and emotions through sounds and music, promoting a positive change in mood and attitude. The app is designed to help users reduce stress, improve sleep, enhance concentration, and increase learning ability.

Unlike meditation or yoga apps, Calmvalera Relax does not require users to learn or practice anything. It can be used anytime and anywhere. Each "Tonic" session lasts approximately ten minutes, addressing topics such as anxiety, inner restlessness, and phobias.
