Island Pulse vs JS Shell

What matters, right on your Lock Screen and Dynamic Island. Island Pulse gives you an API endpoint and a secret Bearer token. Your automations send HTTPS POSTs with JSON; your iPhone turns those updates into Live Activities on the Lock Screen and Dynamic Island. Use it for deploys, sales pings, home automations, or anything you can trigger over HTTPS. HOW IT WORKS • Copy your endpoint and Bearer token from the app and use them in Shortcuts, GitHub Actions, cron, Zapier, or your own code. • Every request must include a job_id so updates route to the right Live Activity stream. • Use title for what people see as the activity title. Use message for the main text. • History stays on this device so you can see what arrived recently. FREE • One active job at a time (one concurrent Live Activity stream for your account) • Title and message on the Lock Screen; you define what they mean • Default layout only • Live Activity plus the last 10 completed runs in your in app log PRO • Multiple concurrent jobs within iOS limits* • Last 30 days of run history • Custom job names and icons • Longer runs with automatic renewal when you need an activity to stay visible • Premium themes and layout options *Subject to iOS system limits (for example, up to five concurrent Live Activities per app) and device capabilities. Subscriptions are billed through your Apple ID. Pricing and renewal terms are shown in the app before purchase.

JS Shell is a pocket-sized developer console that lets you write, run, and test web code (HTML, CSS, JavaScript) directly on iOS and macOS. No Xcode, no laptop, no remote server. Paste a page in, tap run, and it loads in a real WKWebView served from a local HTTP origin. A real secure-context origin on iOS, so modern web APIs — from WebRTC to Geolocation — behave the way they should. KEY FEATURES Local HTTP server. An in-process server bound to the loopback interface. Provides a real secure-context origin so modern Web APIs work out of the box. Not reachable from outside the device. JavaScript REPL. A full JavaScript runtime backed by JavaScriptCore. Type js to enter the REPL. console.log, fetch, setTimeout, setInterval, Promises, and async await are all available. Real Promises, real microtasks, real JSON parsing, real URL parsing. Geolocation support. Test navigator.geolocation on a real iOS device. Permissions are handled by the system, just like Safari. Useful for validating location-based web features without deploying to a server. Persistent file system. Files you paste live in your Documents directory and survive app restarts. Each downloaded package gets its own directory. iCloud backup picks them up like any other app data. SQLite key-value store. A real B-tree on disk via SQLite. Read and write from your pages with same-origin fetch. No CORS configuration required. curl. A subset of curl built on URLSession. The flags X, H, d, i, I, o, A, m, v are supported. Pretty-prints JSON responses and saves binary blobs to the virtual filesystem. Archive extraction. In-process tar, tar.gz, tgz, gz, and zip extraction. No shelling out. Download a release tarball with curl, extract it, and run it immediately. Voice commands. Tap the mic, speak a command. Apple Speech framework converts speech to text. Auto-submits on detected silence. Voice commands are saved to the scripts list for one-tap re-run. Saved scripts. Save any sequence of commands as a named script. One-tap to re-run later. Voice-recognized commands are auto-saved to the scripts list for instant replay. Mac Catalyst support. Runs natively on macOS as a Mac Catalyst app. Multi-window, resizable, fullscreen-capable. The same code that runs on your iPhone runs on your Mac. DESIGNED FOR DEVELOPERS JS Shell is a tool for people who want to test web code on a real iOS device without installing Xcode, syncing files, or setting up a tunnel. It is especially useful for: Testing geolocation, camera, and microphone permission flows on iOS. Validating fetch, CORS, and cookie behavior on a real iPhone. Building small offline web tools that need persistent state. Running JavaScript snippets without opening Safari Inspector. Debugging mobile rendering edge cases on the device itself. PRIVACY JS Shell does not collect any user data. There is no telemetry, no ads, no analytics, no third-party SDKs, no remote configuration. Everything you type, paste, or download stays on your device. The local HTTP server only listens on the loopback interface and is not reachable from any network. The app forwards camera, microphone, speech recognition, and location permissions to web pages you load, exactly like Safari does on macOS. The first time a page tries to use them, iOS shows the standard system permission prompt. The first time a page tries to use them, iOS shows the standard system permission prompt.
