House ECG vs Desktop Mirroring

Every building has its own vibration rhythm. House ECG uses the motion sensors in a dedicated iPhone to observe that rhythm over time—much like a long-term ECG for a house. Mount an iPhone 8 or newer at a fixed structural point, connect continuous power, place the screen face up, and keep House ECG open in the foreground. The app measures motion 50 times per second, establishes an initial reading for that exact installation point, and compares later stable observations with the same point. House ECG includes: - Three-direction vibration measurement, with north–south and east–west directions shown only when the phone's direction reading is reliable. - Welch spectral averaging with Hann windows and 50% overlap to reduce the influence of incidental bumps and noise. - A low-cost continuous watcher that performs fuller analysis only after a candidate vibration is detected. - Local candidate-event history and user labels for earthquake-like events, traffic, machinery, impact, device movement, or unknown events. - On-device SQLite storage for initial readings, history, and raw candidate-event waveforms. - Optional Sign in with Apple for Email notifications; basic monitoring does not require an account. - Optional comparison with the public USGS global earthquake catalog, approximate address, and weather context when an Email notification is requested. - Clear installation guidance and automatic reminders to create a new initial reading after moving, lifting, remounting, rotating, or changing floors. House ECG was conceived by a Taiwan-licensed civil engineer and National Taiwan University graduate who has participated in earthquake-related work since the 1999 Chi-Chi earthquake. The method is grounded in established vibration-analysis practice and is being improved through long-term field testing. Important: House ECG is a change-screening and field-observation tool. It is not a certified seismometer, earthquake early-warning system, structural safety certificate, or substitute for an inspection by a qualified professional. It does not declare a building safe or unsafe.

Desktop Mirroring - your Mac's screen, right in your pocket Your Mac is across the room and you just need to use it. Is the build done? Did the download finish? What was that notification? Your Mac mini is plugged into the TV and there is no monitor on the desk. Desktop Mirroring puts a live, readable view of your Mac's screen on your iPhone or iPad - connected in one tap over your own Wi-Fi - and lets you work it from there. MADE TO BE REACHED Not everyone can sit down at a computer. If you are bedridden, recovering, or cannot sit upright for long, the Mac on your desk is out of reach and the phone in your hand is the only computer you can actually use. Desktop Mirroring closes that gap: the Mac's screen comes to your device, and your taps, swipes and typing go back to the Mac. No extra hardware, no second computer, nothing to stretch for. HOW IT WORKS Connect in one tap - Your Mac runs a small menu-bar tool. On the same Wi-Fi, your iPhone finds it automatically. No accounts, no pairing codes, no cables. Tap your Mac's name and you are looking at it. Use it from where you are - Move the pointer, tap, scroll, drag and type. The controls stay simple: a trackpad-style surface, a keyboard, and a few keys for Mission Control and Esc. Read it from across the room - High-resolution mirroring over your local network, so windows, menus and tabs stay readable. The stream adapts its bitrate to your connection instead of stalling. Look in from anywhere - Not on the same Wi-Fi? Turn on Remote in the Mac app and view your Mac's screen over iCloud, with your own Apple ID. Remote is view only: over the internet the app only looks. MORE TO LOVE Pick the display you share - Multi-display Mac? Choose which display gets mirrored from the Mac menu bar. Private by design - On your Wi-Fi the video and your input go straight between your devices. Remote view runs through your own private iCloud. No sign-ups, no third-party servers. Works with any Mac - MacBook, iMac, Mac mini: if it runs macOS, it is ready. Free to try - Full use, free, for 3 days after your first connection. After that, Premium keeps it going.
