【Function introduction】

1.Mobile phone signal monitoring: Real-time tracking and display of mobile phone signal strength, one-click query of SIM card status and operator details. In-depth exploration of base station services, including current service cells, neighboring cells and network location areas (LAC), tracking areas (TAC), cell identification (CI) and other advanced information, to help you fully understand the mobile phone network environment and optimize signal reception quality.

2.WIFI signal monitoring: Real-time detection of signal strength, display of key information such as MAC, channel, IP, rate, etc., detection of security, and listing of connected devices to help you easily manage the network.

3. Satellite signal: real-time tracking of satellite signals, obtaining satellite information, including nationality name (US GPS, China Beidou, EU Galileo, Russia GLONASS, Japan Quasi-Zenith Satellite System, India IRNSS), number of satellites, real-time satellite location, availability, longitude and latitude, address and other information.

4. Bluetooth signal: real-time detection of Bluetooth signal strength, obtaining information such as the current connected Bluetooth MAC address. Query paired list, scan and discover nearby Bluetooth devices and other functions.

5. Sensor information: obtain all available sensor devices on the device, and read their current value, power, accuracy and other related data in real time. And used for practical applications, such as thermometer, compass, brightness meter, barometer and other actual measurements.

6. Speed ​​tracking: display the device moving speed (km/h, mph, speed knots optional), direction and number of satellite connections to ensure accurate navigation and positioning.

7. Magnetic field monitoring: real-time monitoring of magnetic field strength, and setting threshold automatic alarm.

8. Route tracking: Query the complete path from your current Internet IP to the target website IP, covering the IP address, number of hops, delay time and internal and external network status of each hop server along the way. One-click insight into the entire network, helping to accurately evaluate and improve the current network quality.

9. PING test: Evaluate the quality of network connection, accurately test the accessibility of the target network IP, and monitor the packet loss rate, network delay and jitter in real time. Support detailed test log records, so that network problems can be found, and help quickly locate and solve network failures.

10. Realize the real-time noise detection function, which can continuously monitor the environmental noise value, and support the preservation and retrospective viewing of historical data.

One-stop solution to signal problems! Integrate mobile phones, base stations, WIFI, Bluetooth, GPS and magnetic field detection functions, track signal strength and device information in real time, and accurately locate the best signal point. It also comes with powerful tools such as speed query, GPS precise positioning, route tracking, PING test, etc., to meet your signal detection needs in all aspects.
Track signal strength and pinpoint the sweet spot.

v1.10.58: *In the WiFi Signal section, it might be a good idea to add a round dial Wi-Fi signal strength meter, just like the one in the Phone Signal section. It's a bit puzzling that this was not included. *Although this app is undoubtedly filled with impressive & detailed info, it can be slightly overwhelming, particularly for individuals seeking general & commonly known info.

This app has saved me two times, last year I lost one of my hearing aids and was able to pinpoint it within a 3 foot radius. I installed the app and within 30 minutes we found it. Then recently my wife lost one of her airpods and we were able to pinpoint it within a 3 foot radius. The only complaint is if you don't purchase it you will get lots of ads. the device you are looking for must be on or you will not be able to detect it. I purchased the app, it saved me lots of money.
