Fly through the entire solar system on your phone — every planet, moon, ring system, and the Sun rendered with real NASA imagery, true-3D atmospheric scattering, and cinematic post-processing.

In one sentence: RealTime Space is a phone app that lets you fly a ship through a 3D model of the solar system, rendered live in WebGL inside a native iOS or Android shell. It is shipped and live on both the App Store and Google Play.
This repo holds both platforms of RealTime Space, cleanly separated:
SwiftUI + WKWebView wrapping a Three.js/WebGL solar system renderer. Full source, Xcode project, and textures live in ios/.
Status: ✅ Live on the App Store. Version 1.3.2 (build 23) in the Xcode project.
The Android port — a WebView shell around the same renderer, with all web assets bundled. Source in android/.
Status: ✅ Live on Google Play. Version 1.5 (versionCode 9) in android/app/build.gradle.kts.
- The 3D renderer in JavaScript on top of three.js: planets with atmosphere and ring shadows (
ios/Planet.js), moons (ios/Moons.js), the Sun and stars (ios/Star.js), orbits (ios/OrbitalMechanics.js), flight physics (ios/NavigationPhysics.js), nebulae, asteroid belt, black hole, warp effect and HUD, wired together inios/main.jsandios/RendererCore.js. - The "Codex" deep-space layer in
ios/codex/: constellations, exoplanets, galaxies, a cockpit view, and a live-data panel (ios/codex/LiveData.js) that shows the real current ISS position and today's near-Earth asteroids. - The iOS app shell in SwiftUI: the web view and JS bridge (
ios/WorkingPortalWebView.swift,ios/GalaxyBridge.swift), a customappassets://scheme so WebGL can load bundled textures (AppAssetSchemeHandler.swift), the native radar (ios/SimpleRadarView.swift) and audio (ios/AudioManager.swift). - The Android port in Kotlin + Jetpack Compose:
MainActivity.kt, a JS bridge that mimics the iOS message handler (WebBridge.kt), and a Compose port of the iOS radar (RadarView.kt). - The paywall on both stores: a 60-day free trial, then a one-time non-consumable unlock (not a subscription), plus gift codes checked against SHA-256 digests. StoreKit 2 on iOS (
StoreManager.swift, trial date kept in the Keychain so a reinstall does not reset it) and Google Play Billing on Android (StoreManager.kt).
Upstream, not mine: three.js (r150, bundled at ios/textures/lib/three.bundle.js) does the WebGL work. Planet imagery comes from NASA and other texture sets listed in CREDITS.md and THIRD_PARTY_NOTICES.md. Live data comes from wheretheiss.at and NASA's NeoWs API.
- iOS: open
ios/RealTime Fidget.xcodeprojin Xcode (the project still uses its old working name, "RealTime Fidget"). The deployment target is iOS 26.0, so you need an Xcode with the iOS 26 SDK.ios/Products.storekitlets you test the unlock locally without App Store Connect. - Android: from
android/, run./gradlew assembleDebug(JDK 17, compileSdk 36, minSdk 26). A release build reads signing keys fromandroid/keystore.properties, which is not in the repo, so only debug builds work out of the box. - No build step for the web renderer: the HTML, JS and textures are bundled into each app as plain files.
- The iOS and Android web assets are two separate copies (
ios/andandroid/app/src/main/assets/web/), kept in step by hand. Several files (for examplemain.js,Planet.js,index.html) currently differ between them, so the two apps are not guaranteed to be identical. - The live-data panel needs a network connection. Offline it falls back to the last good data or a "no signal" message.
- There are no meaningful automated tests; the Xcode test targets are the default templates.
