BLE Scanner vs Sentio

Lost your Bluetooth device? BLE Scanner & Bluetooth Finder instantly scans for nearby Bluetooth devices and helps you locate them. No pairing, no auto-connecting, and no data collection. Whether it is wireless earbuds, Bluetooth headphones, speakers, smartwatches, fitness bands, or tracking tags, this app helps you find what is missing using real Bluetooth signal strength. HOW IT WORKS 1. Open the app to start scanning for nearby Bluetooth devices 2. View detected devices sorted by distance using signal strength (RSSI) 3. Filter by proximity, manufacturer, or signal strength to narrow your search 4. Tap a device to enter focused tracking mode with a radar view 5. Watch real-time signal bars and distance as you move closer 6. Save a scan session to keep the results, or open the live map to see your trail and located devices KEY FEATURES • Real-time Bluetooth device scanner for nearby BLE devices • One-tap focused tracking with a radar-style interface • Filter by proximity, manufacturer, or signal strength • Signal strength indicator with RSSI-based distance estimates • GPS location tagging: save where each device was detected and view it on a map • Live map: see your movement trail alongside located devices • Scan sessions: save, name, and revisit device lists anytime • Ignore devices: hide unwanted results to keep your list clean • CSV export: save and share your results, including latitude, longitude, and accuracy • Manufacturer detection and detailed advertisement info • Star favorites and revisit frequently tracked devices • Hidden camera detection: scan for Bluetooth-enabled cameras in hotels, rentals, and unfamiliar spaces • Privacy first: no account required, and your data stays on your device PERFECT FOR • Finding lost wireless earbuds and headphones • Locating a misplaced smartwatch or fitness tracker • Detecting hidden Bluetooth cameras • Finding tracking tags • Checking Bluetooth signal coverage in a space • Exploring what Bluetooth devices are around you Note: devices must be powered on, advertising, and within range to appear.

Sentio turns the sensors already in your iPhone — microphone, camera, torch, accelerometer — into a set of measurement tools, and keeps every measurement on the device. WHAT IT DOES Sentio provides a growing registry of measurement tools. Each one uses the phone's sensors in a specific way: • Spectrum — record ambient sound and see its frequency content, peaks and decay • Color and light — measure colour and brightness with the camera's exposure locked • Blinking — detect and time periodic light sources • Knock — tap an object and capture how it rings and how quickly it damps • Polarization — measure how much light passes through at a quarter turn • Composite tools that drive the torch or the haptic engine and measure the response Some tools use two phones together — one emits, one measures — over a direct Bluetooth link, with no account required. ORGANISE WHAT YOU MEASURE Measurements attach to a simple catalog: categories, objects, and the scenario you measured them for. You can also capture first and file it later. Any measurement can be given a ground-truth label after the fact, so a session of guesses becomes a record you can actually check yourself against. Guided activities chain several tools into one procedure when a single sensor is not enough. OFFLINE BY DEFAULT Everything runs on the device. There is no account, no upload step, and no network call needed to take or view a measurement — the app is fully usable in Airplane Mode, and that is the normal way to use it. Signing in with Apple or Google is entirely optional and does one thing: sync your own catalog between your own devices. HONEST ABOUT WHAT IT IS NOT Sentio is an instrument, not an oracle. It reports what the sensors measured and how it derived the numbers. It does not claim laboratory accuracy, it is not a medical or diagnostic device, and it should not be used to make safety decisions. Phone sensors vary between models; the tools are built around relative and resonance-based features precisely because absolute levels are not comparable across devices. PERMISSIONS • Microphone — required by the audio tools, used only while a measurement is running • Camera — required by the optical tools • Bluetooth — only for the two-phone tools, to find the other handset No advertising, no analytics SDK, no third-party trackers.
