IronScope vs Presenter PDF

IronScope uses your iPhone's built-in magnetometer to show nearby magnetic-field changes in microteslas (µT). It is a phone magnetometer field meter for close-range ferromagnetic objects, learning, and everyday curiosity. It is not a professional metal detector and must not be used for security screening, mining, infrastructure locating, or safety decisions. KEY FEATURES • Real-time magnetic field reading in µT • Color-coded gauge with optional audio alert • One-tap calibration to the local magnetic baseline • Clear unavailable-state messaging on simulators or unsupported devices • Fully offline — no network, no tracking, no ads, no account PRACTICAL USES • Observe field changes near keys, screws, magnets, and steel objects • Compare magnetic and non-magnetic items at close range • Demonstrate magnetism in a classroom or maker setting • Check how magnetic cases, mounts, and accessories affect your phone HOW IT WORKS The iPhone magnetometer reads the ambient magnetic field. IronScope subtracts your calibrated baseline, often near Earth's natural 25–65 µT range, and shows nearby changes as excess signal. Readings vary by phone model, orientation, calibration, cases, magnets, and nearby electronics. LIMITATIONS Smartphone magnetometers are not professional metal detectors. Non-magnetic metals such as aluminum and copper may not change the reading. Deep or hidden objects are not reliable targets. Keep the phone away from strong magnets that could affect device sensors. PRIVACY Magnetometer readings are processed locally. No audio, video, location, analytics, ads, account, or tracking is used.

Turn exported PDF decks into a focused presentation—without rebuilding slides in another app. PDF Presenter is built for talks, classes, and meetings when your slides already live in a PDF from Keynote, PowerPoint, or any export tool. Open a file, go fullscreen, and move through pages with confidence. Present like a pro • Fullscreen slide view with a clear slide counter • Navigate with arrow keys, Space, Page Up/Down, and swipe gestures • Tap the left or right edge of the screen for quick previous/next (where supported) • Minimal on-screen chrome so your content stays center stage Open decks your way • Import PDFs with the system file picker • Reopen your last opened deck in one tap • Open PDFs shared from other apps and file links (security-scoped access) Made for iPhone, iPad, and Mac • Native experience on iOS and macOS • macOS: presentation flow in the main window with fullscreen support • Keyboard shortcuts on Mac (⌘O to open a PDF from the menu) Free to try, Pro to go further • Free: preview the first 20 slides of any deck • PDF Presenter Pro: unlimited slides and ongoing presenter improvements Information & privacy • In-app access to privacy policy and terms • Optional analytics you can control during onboarding Whether you are rehearsing on your Mac or presenting from your iPad, PDF Presenter keeps the workflow simple: open PDF → present → done.
