Ratings and reviews

It works like a charm. I am able to read other people's devices thanks to the built-in OTG on my phone. Any USB device connected to my phone, this app will try to decode the best of information that I need about any device connected to my phone.

Great , It worked , Displayed the device serial number as well which i needed to know for service renewal... Loved it.gr8 app

No longer works with Android 13; constant crashes on launch.
