Metal Detector EMF - RaPo

RaPo is a lightweight and practical tool for metal detection and electromagnetic field (EMF) intensity testing.

It uses the built-in magnetic sensor of your smartphone to read magnetic field data in real time, helping you quickly detect surrounding metal objects and changes in the electromagnetic environment.

You can use it for:
1. Detecting metal objects hidden underground, behind walls, and in other places
2. Assisting in the detection of internal items in blind boxes that contain metal, magnets, and other components
3. Real-time viewing of magnetic field values and waveform changes to intuitively understand intensity trends
4. Serving as a daily fun detection tool to experience the joy of treasure hunting and electromagnetic detection

Value Explanation
The higher the detected value, the closer you are to metal or strong electromagnetic items. Click to start detection, place your phone close to the area you want to detect, and start your experience!

Kind Reminder
- For blind box detection, it only has an auxiliary effect on scenes where the blind box contains metal, magnets and other components, and the distance between the phone and the blind box is sufficiently close.
- This app is for reference only and cannot be used as a professional measurement tool.
- Some non-ferrous metals (such as gold, silver, copper coins, etc.) are non-magnetic and cannot be detected.
- This app relies on the phone's magnetic sensor; it will not work properly on devices without this hardware.
