What is Sia?
Sia is an app for highly sensitive people — people whose nervous system takes in more, and reaches too much sooner. It has one job: make it quieter in the moment it is needed, and, when you want, help you see your life more clearly.
It opens on one question: how much room do you have right now? Barely any: only the breath. Some: short ways in. Plenty: the whole library. The light follows your answer, and nothing is ever demanded.
At the top of the home sits the sun: the one moment Sia thinks is closest to you — because you said where life is a lot, because it helped before, or because of the hour. 36 real situations, each written twice, in English and in German, with the steps and minutes shown before you tap.
Sensory processing sensitivity often appears alongside ADHD, autism and other neurodivergent traits. Sia is not a medical app and not therapy; it addresses the sensory and emotional side that many neurodivergent people share.
Everything that helps in the moment is free, for everyone, always. Sia Plus is the before and the after: preparing for the next time, looking back once it is over, and what your weeks show.
Understanding Your Sensitivity
Sensitivity shows up in different ways for everyone. Researchers have identified four key dimensions that help explain how highly sensitive people experience the world — and Sia is designed with each in mind.
Depth of Processing
You think deeply and notice patterns. Sia provides clear explanations of why each technique works.
Overstimulation
Your nervous system reaches overload quickly. Sia offers immediate support when you need it most.
Emotional Reactivity & Empathy
You feel emotions deeply and sense others' moods. Sia helps you set boundaries while staying open.
Sensing the Subtle
You notice changes others miss. Sia helps you track patterns and validate your observations.
