Stellar: Motion Comfort

Stellar is a motion comfort app designed for passengers who feel unwell during rides, flights, or boat trips. It combines real-time visual guidance with optional 100 Hz based audio to help reduce the sensory mismatch that often appears during travel. As your device senses motion, Stellar turns acceleration changes into calm, responsive visuals. Instead of leaving your eyes disconnected from what your body feels, the app gives you a stable visual reference that moves with the journey. Choose from three visual modes: Minimal offers clean peripheral guidance with a lightweight look. Interstellar turns motion into a spacious field of particles and stars. Live View uses the camera viewfinder with subtle edge effects, helping you stay visually connected to the real world. Audio support is optional. Research shows that sound at 100Hz might help alleviate motion sickness. You can choose a gentle melody calibrated around G2 = 100 Hz, a 100 Hz mono tone, or no audio. For the best experience, use headphones at a comfortable volume and enable transparency mode when available. Stellar is built to stay simple and local. It does not require an internet connection, does not collect or upload health data, location data, audio, or usage history, and only stores your preferences on device. Motion sensor access powers the core visual guidance, and camera access is used only for Live View. Please use Stellar while seated comfortably and holding your phone steadily. Do not use it while operating a vehicle. Results may vary from person to person. Stellar is not a medical product, has not been clinically validated, and should not be considered medical advice. If you experience discomfort, headache, tinnitus, or any other adverse symptoms, stop using it immediately. Stellar supports Chinese and English for the time being.
