Explore the universe of exoplanets — over 6,000 confirmed worlds orbiting distant stars, updated from leading scientific archives. Track new discoveries as they happen and dive into the data behind every planet. EXPLORE THE COSMOS Search, filter, and sort the complete catalogue of confirmed exoplanets. Find planets by discovery method, star type, orbital characteristics, or habitability potential. Every entry includes detailed scientific data from peer-reviewed sources. ATMOSPHERIC SPECTRA Browse JWST and Hubble transmission spectra for planets where atmospheric data is available. Toggle molecular overlays for CO2, CH4, H2O, CO and more to see which absorption features have been detected. 3D SYSTEM VIEW Step into a planetary system in 3D — see each planet's orbit around its host star with realistic shading and a visualisation of the habitable zone. On iPhone and iPad you can also place a system into your environment in AR. COMPARE WORLDS Analyze exoplanets side-by-side — or compare them with Solar System planets like Earth, Jupiter, and Mars. Compare sizes, masses, orbital periods, star properties, and habitability scores to understand what makes each world unique. HABITABLE ZONE VISUALIZATION See exactly where planets orbit within their star's habitable zone — the region where liquid water could exist. Identify potentially Earth-like worlds and understand the conditions for life beyond our solar system.

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.

Verdict

The call

The clearest difference is price: Exoplanet Explorer at Free against Muon Tracker's $1.99. Exoplanet Explorer also leads on ratings volume (70 vs 1) and device support (5 vs 2). Muon Tracker's advantage is in-app purchases (none vs 4) and rating (5.0 vs 4.6). On ads and iOS requirement there is nothing between them.
