srad
Art from life
$2.99 · Designed for iPhone. Not verified for macOS.
Your pulse, steps, and surroundings painted live onto a glowing 3D sphere.
Recently taught manners.
Still dramatic when you sneeze.
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. Sound erupts it with spikes. Motion tilts it, twists it, breathes 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
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 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.
Ratings & Reviews

We taught the sphere some manners.
• It keeps proper rhythm now. On newer iPhones your heartbeat was secretly pulsing in double-time. The sphere now beats honestly, at your pace.
• It stopped interrupting your music. The mic used to silence Spotify like a strict librarian. Now your soundtrack plays on — and becomes part of the art.
• It listens when you say "again." Stop and restart a session and the microphone keeps working, every time. No more silent treatment.
• It lets your Apple Watch rest. The watch used to start measuring everything the moment it woke up. Now it works only while you're creating — your battery will notice.
• It found its rhythm with yours. Resonance — that glow when your heart and steps sync up — actually shows up on walks with your watch now. Go earn it.
• It remembers your taste. Palette, sensitivity, sensors — set them once, they're there tomorrow.
Plus politer permission handling and a healthy pile of invisible fixes.
