Bluetooth Scanner turns your iPhone into a Bluetooth Low Energy explorer. Scan the environment, save the devices you care about, and inspect everything they broadcast — right down to the raw advertisement data. No cloud, no account, no internet connection needed: everything happens locally, straight from your device's Bluetooth hardware. FEATURES • Live scan of nearby Bluetooth LE devices, sorted by signal strength • Save devices to your list and give them your own nicknames • Swipe to remove a saved device at any time • Full detail view per device: signal strength (RSSI), TX power, MTU, connectable state, service UUIDs, manufacturer data, and more • Automatic background refresh keeps saved devices' signal strength and data up to date while you're on the Home screen • On-demand decoding of common BLE beacon formats — iBeacon, Eddystone, and Apple Continuity — shown as readable fields instead of raw hex • Export your saved device list as a JSON file via the share sheet • Scan preferences: auto-stop timer, hide unnamed devices, minimum signal strength filter — all remembered between launches • Dark mode by default, with a light mode toggle — your choice is remembered too • Fully offline operation, no tracking, no analytics PRIVACY Bluetooth Scanner does not collect, transmit, or store any data outside your device. Scanned and saved devices exist only for your current session; only your display preferences (theme and scan filters) are remembered locally on your device.

When you open an HTML file in the iPhone Files app, iOS just dumps lines of raw code on your screen. Buttons do not work, styles break, and Safari cannot open local file links. HTML Opener fixes that. It runs your local HTML, CSS, JavaScript, and images in a real WebKit browser directly on your iPhone and iPad. No Mac, no terminal, and no local server required. WHAT IT SOLVES - Files app dumps raw code and text on screen instead of rendering the webpage - Safari has no address bar option to open local file:// links - Opening a single file breaks CSS styles and image assets in neighboring folders - Setting up a local server on your computer just to check mobile layout is tedious REAL WEBKIT BROWSER RENDERING Built on iOS's native WKWebView engine. Buttons, forms, CSS styling, canvas animations, and modern JavaScript run exactly as they would in Safari. OPEN AN ENTIRE PROJECT FOLDER Select a folder containing style.css, script.js, and an images directory alongside your HTML file. All relative file paths resolve automatically with zero broken images or missing styles. DESKTOP & MOBILE VIEW TOGGLE Switch between phone layout and 1024px desktop view with a single tap. Review horizontal dashboards, data tables, and desktop web tools without broken layouts. FULLSCREEN MODE Hide navigation bars and margins to give your web content the entire display. Web apps and tools feel like installed native apps. FOUR SIMPLE ACTIONS 1. Open a local file or folder 2. Quick Switcher to jump between recent projects 3. Auto-launch your primary tool as soon as the app starts 4. Clear cache, toggle dark theme, and customize display options WHO IT IS FOR - Anyone stuck when iPhone opens HTML as raw code - Developers and designers testing web prototypes on actual iOS hardware - Anyone running self-built dashboards, calculators, or tools on the go - Students learning web development who want instant mobile testing PRO (ONE-TIME PURCHASE, NEVER A SUBSCRIPTION) Removes ads completely.
