As someone in cybersecurity, it is handy as a low frequency RFID reader as Android phones only support higher frequency. Having something compact and in a single unit (compared to a Proxmark) makes it easier to 'grab-n-go'. It is neat to show people how insecure common access control systems are.

I've also used it as a universal remote more than a few times on devices that didn't come with a remote. The App running on a phone makes it somewhat easy to transfer new remote templates to the Flipper over Bluetooth.

It also comes in handy as a serial adapter as it has GPIO pins you can connect to things (UART headers).

The RF transceiver is also cool to capture RF remotes (garage doors, overhead fans, etc.) and replay them.

Do you mean the non IR kind?

    Yes, RF (radio frequency) remotes I've seen include my garage door opener, some overhead fans in bedrooms, gates, remote outlet/light controllers.

    Yeah, the Flipper Zero has a "sub 1GHz" transceiver, from memory its a CC1101?

    It can receive and transmit from about 300MHz to 930MHz (with a few gaps in between).

    I've used my Flipper to sniff the signals for my wireless controlled projector screen, projector, and home theatre amp. I then used the data I sniffed to program an ESP32 with a CC1101 module attached, so I can roll down the screen and turn on the project and amp via wifi (with Homebridge and iOS Home app).

    I later sniffed my garage door opener, added that into the ESP32/CC1101 gadget. I needed to add a better antenna to make sure it reliably had range to get to the garage door, but it now works more reliably than the keychain fob, and I can use an "arrived home" automation to have the door open without me needing to stop the motorcycle and take off my gloves and get the key fob out of my pocket. I may replace this with an Arduino/CC1101 triggered by the hi beam switch.

    The Flipper Zero is a super useful tool when having ideas like this, but like most tools, it really does sit in the drawer most of the time. But I'm glad it's there, I don't regret a cent of it's purchase price.

    I am sure they did. Non IR kinds basically are RF (radio frequency) kinds.
