Muon Tracker
Step Into the Invisible World
USD 1.99 · Designed for iPad
Track cosmic particles in real time. Simulate muons, explore physics, and step into the invisible universe — right from your pocket with Muon Tracker.
Muon Tracker brings the fascinating phenomenon of muon detection right to your device. Designed for science enthusiasts, students, and educators, this app simulates the detection of high-energy muons—particles created when cosmic rays collide with the upper atmosphere—and visualizes them in real time.
What it does
• Simulates the arrival of cosmic muons based on your current location (latitude, longitude, and altitude).
• Accurately models muon flux and angular distribution, including diurnal and seasonal variations.
• Detects and visualizes muon tracks with animated directional paths, energy estimates, and impact points on your screen.
• Displays real-time rates and calculated flux in particles per second and per square meter.
• Offers a data panel where you can explore and export historical events with timestamps, angles, and energy in GeV.
Scientific accuracy - Muon Tracker is powered by a physics-based simulation engine that factors in:
• Atmospheric depth modeling to vary muon rates with elevation
• Geomagnetic latitude effects to reflect regional muon flux
• Angular dependency using a cosine-squared distribution to simulate slant tracks
• Randomized yet statistically valid energy distributions typical of atmospheric muons
The simulation mimics real-world detection environments scaled to your device’s screen size. Whether you’re at sea level or on a mountain, the simulated flux adjusts accordingly.
Ideal for
• Physics students learning about particle physics and cosmic radiation
• Educators demonstrating subatomic phenomena in classrooms
• Science fans and curious minds exploring the universe from their pocket
Features
• Intuitive and elegant SwiftUI interface
• Toggle between persistence mode (trails) and flash mode (instant hits)
• Auto-switch between track visualization and point hits based on device orientation (vertical ↔ horizontal)
• Muon tracks rendered in 3D space, dynamically responsive to device rotation
• View location-based detection stats, including GPS position and altitude
• Adjust altitude manually to observe its effect on muon flux
• Real-time log of muon events, including incidence angle and particle energy
• Plot angular distribution of muon track directions
• Export your event log as a CSV file for deeper analysis
• Works fully offline, with smart location-based initialization
Step into the invisible universe. Download Muon Tracker and detect the particles that travel from space through you every second.
