What is flipper-rfid-metal-detector?

This C app for Flipper Zero turns the 125kHz RFID antenna into a basic metal detector by detecting changes in the electromagnetic field. You get a screen bar graph showing signal strength, plus audio tones that rise in pitch, vibration, and LED flashes as metal approaches within a few centimeters. Drop the prebuilt .fap file onto your Flipper's SD card in apps/Tools, or build it with ufbt tools common in github flipper zero firmware projects.

Why is it gaining traction?

It stands out in the flipper zero apps scene on GitHub with adjustable sensitivity to tune out noise, plus toggleable alert modes like sound-only or vibro-only, making it more usable than raw RFID experiments. Developers grab it for the quick visual feedback and easy controls—left/right for sensitivity, OK to cycle modes—without needing custom flipper github unleashed or momentum firmware tweaks. At 46 stars, it's a fun entry in the ecosystem alongside sub-GHz tools and evil portal apps.

Who should use this?

Flipper Zero owners hunting casual hardware hacks, like makers scanning pockets or testing 125kHz coils during pentests. Hardware tinkerers evaluating flipper zero alternatives on Amazon or sites to kaufen gebraucht will like the experimental vibe. Avoid if you need pro range; it's for hobbyists extending their device with simple github flipper zero files.

Verdict

Grab it for a 5-minute laugh if you're deep in Flipper Zero firmware mods—solid docs and MIT license make it low-risk. With just 46 stars and 1.0% credibility score, it's raw and untested, so treat as educational toy, not daily driver. (198 words)
