srad turns your body into an artist. Using sensors from your iPhone and Apple Watch, srad renders a living 3D sphere that responds to who you are and what you're doing — right now. Your heartbeat pulses the form. Your footsteps send ripples across its surface. The magnetic field around you shifts its color. Motion tilts it, twists it, breathes it. And now your body doesn't just move the art — it plays it. This is not a health app. There are no charts, no metrics, no goals. srad is personal digital art — generated from the data your body produces every second. What shapes the form: # Heart Rate — your pulse drives the sphere's rhythm, expanding and contracting the surface with every beat # Step Count — each footstep sends a wave across the equator; walking builds a traveling orbit # Accelerometer — gravity deforms the form and tilts the color gradient # Gyroscope — rotation adds a vortex twist and surface spin # Magnetometer — the invisible magnetic field around you rotates the color hue in real time # Barometer — atmospheric pressure thickens or thins the corona ring # Location — altitude shifts color warmth; speed drives overall energy # Microphone — sound erupts the surface with geometry spikes and ripples Soundscape — your body, in sound srad now turns your living data into a generative soundscape, in real time. Your heartbeat is the bass, your steps are the rhythm, your motion stirs the air around you, and when your pulse and pace fall into sync, a resonance glow rises — in the sphere and in the sound. Best experienced with EarPods in and your phone in your pocket on a walk. Nothing is recorded. Sensor Resonance When your heart rate and step cadence fall into sync — the natural state of a comfortable walk or run — a special resonance glow appears on the sphere. A traveling hotspot that only exists when your body finds its rhythm. Something to notice. Something to earn. Color palettes Choose from six hand-crafted palettes — Ocean, Sunset, Forest, Monochrome, Neon, and Default — each transforming the sphere, and its soundscape, into a completely different world. Immersive mode Double-tap anywhere to hide all interface elements. Just you, and the art. Privacy first All sensor data stays on your device. Nothing is uploaded, stored, or shared. srad requires no account and collects no personal information.
