BLE Scanner 4.0 vs Magnetometer+ Metal Detector

No. 1 Scanner Utility app for BLE devices and trusted by developers, hobbyists, and everyday users worldwide, BLE Scanner 4.0 is your go-to app for Bluetooth Low Energy exploration. Easily discover, connect, and manage your Bluetooth Low Energy (BLE) devices. Whether you’re a developer testing BLE device signals or a user tracking your smart gadgets, BLE Scanner gives you powerful tools to scan, analyze, and connect all in one app. Why BLE Scanner? - Instant Discovery: Quickly find nearby BLE devices with real-time signal strength (RSSI). Lower the number the closer you are to the source i.e. -25 is very near and -80 is far from your BLE devices. - Radar View: Visualize device distance and movement around you. - Smart Filters: Search by name, UUID, RSSI, or major/minor values. - iBeacon & Eddystone Support: Scan, monitor, and analyze beacon data seamlessly. - Data Export: Save scan history or export logs to CSV for advanced analysis. - Custom Advertising: Create your own BLE advertising packets for testing & IoT projects. - Upload data to the cloud: Upload your BLE device data on your own cloud using HTTPS or MQTT URL. - Secure Connections: Connect to GATT services and explore characteristics. Built for Developers & Engineers - Inspect GATT services & characteristics - Read and write BLE characteristics - Debug BLE communication issues - Ideal for firmware testing & validation Privacy First • No account required • No personal data collected • BLE scanning performed locally on your device Privacy Policy: https://www.bluepixeltech.com/appVersion/privacy-policy-blescanner.html Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Follow us on: Facebook: https://www.facebook.com/blescanner X: https://x.com/blescanner Comments, questions, or suggestions?

Magnetometer+ turns your iPhone's magnetic sensor into a metal detector and stud finder for iron and steel hidden in walls, floors and furniture, and shows the magnetic field around you in µT. ▶ WHAT IT FINDS — AND WHAT IT DOES NOT It detects ferrous metal: screws and nails in studs and joists, steel pipes, rebar, hinges, brackets and door strikes. The range is a few centimetres, so hold the phone against the surface and sweep slowly. It cannot detect gold, silver, copper, aluminium, wood or plastic. Those materials are not magnetic, and no phone sensor can find them. If you are looking for buried coins or copper wiring, this is not the tool. ▶ CALIBRATES FROM YOUR HAND Every phone's magnetic sensor carries a large built-in offset from its own speaker and battery magnets. Magnetometer+ learns that offset while you turn the phone, so tilting the phone does not look like metal. When the meter opens, a progress bar shows how far calibration has come: turn the phone slowly in every direction, and when the bar is full the reading goes live with a short vibration. Zero here re-learns it wherever you are. ▶ THREE METER MODES • Auto — a radial gauge of the field deviation • Earth Field — total field strength with a latitude band (low, normal, elevated, high) • Metal Detector — deviation from the background field with an intensity verdict, plus optional vibration pulses that quicken as you get closer ▶ SCANNER AND STUD FINDER The Scanner tab has a metal scanner for sweeping a surface and a Stud Finder that marks the strongest point as you slide the phone flat across a wall. It finds the nails and screws that hold drywall to the studs; it does not see the wood itself. ▶ COMPASS A compass with magnetic north or true north and the local declination. ▶ LIVE DATA • X, Y and Z field components on a live chart • Min, average, max and peak with elapsed time • Sensitivity from 0.5x to 2.0x • µT, mT and Gauss units ▶ HISTORY AND EXPORT • Readings are saved with a 7-day trend and a plain-language comparison • Favourites and side-by-side comparison of two readings • Continuous one-second logging with CSV export • Share a reading as an image, optional GPS tag on saved readings • Statistics report, unlocked for 24 hours by watching a short ad USEFUL FOR DIY AND RENOVATION · FINDING STUDS AND JOISTS · CHECKING FOR REBAR OR PIPES BEFORE DRILLING · PHYSICS CLASS AND MAGNET EXPERIMENTS
