Core features are free, with optional paid sessions and courses.

Available on iPhone, iPad, Mac, Apple Vision, and Android. No account required. Operated by Peaceflow OÜ, Estonia. Available in English (default) and German (at https://entersia.com/de). Sia helps the estimated 15-30% of people with sensory processing sensitivity (SPS) — often called highly sensitive people — navigate everyday challenges. The app is grounded in Dr. Elaine Aron's DOES framework (Depth of processing, Overstimulation, Emotional responsivity, Sensitivity to subtleties) and co-created with HSP community members and experts. All personal data stays on-device with AES-256 encryption. Sia is not a meditation app or therapy replacement — it is a structured, practical toolkit for specific real-life situations. ## Understand Your Sensitivity - [HSP Profile Quiz](https://entersia.com/quiz): Five-dimension assessment measuring depth of processing, overstimulation, emotional responsivity, sensory sensitivity, and subtlety awareness - [How It Works](https://entersia.com/how-it-works): How Sia's situation-based approach works, including the "Right Now" (immediate relief) and "Go Deeper" (understanding) system - [Discover Feed](https://entersia.com/discover): Curated daily content feed of situations, techniques, and insights ## Navigate Real-Life Situations - [Situation Guides](https://entersia.com/situations): 37+ step-by-step guides for real-world challenges like sensory overload, social exhaustion, workplace overwhelm, conflict recovery, and more - [Topics](https://entersia.com/topics): Browse situations and techniques organized by theme ## Build Your Toolkit - [Techniques Library](https://entersia.com/techniques): 100+ evidence-based calming and coping techniques including breathwork, grounding, boundary-setting, and nervous system regulation - [Features Overview](https://entersia.com/features): Full list of app capabilities including personal Relief Toolbox, offline mode, dark mode, and accessibility features ## Find Your HSP Career Path - [Career Finder](https://entersia.com/career-finder): Interactive quiz matching highly sensitive people with careers suited to their strengths - [Careers Directory](https://entersia.com/careers): Comprehensive directory of 76 HSP-friendly careers across 8 categories — technology, healthcare, creative arts, counseling, writing, research, teaching, and environment.
