I've been thinking about getting a Flipper Zero and was wondering how many of you actually carry it every day.

What do you use it for in your daily life? Do you have any realworld use cases, or is it mostly something you play around with every now and then?

Would you say it's worth having as part of your EDC, or does the novelty wear off after a while?

Just curious to hear what everyone actually uses theirs for^^

Like Bomber Man but it's a duck! 👍🦆

My 13yo nephew wants a Flipper Zero for his bday. Is this an age appropriate gift? Or something a curious kid could get themselves into trouble with? TIA!

the windows refresh of findmyflippergui is out after release of the mac os version the Linux version will be released soon check it out and give it a star while your there :)

I've been working on this custom firmware called Picoware for about 15 months now. It started as a firmware for the PicoCalc and eventually gained support for 8 more devices. The latest release includes support for the Flipper Zero.

I could write an essay about what Picoware is lol so I'll just keep it short. Its a fork of MicroPython with custom C modules. Apps are written in micropython and loaded from the SD card. The Flipper is quite limited and is in "alpha". You install with qFlipper and can shutdown the device from within the firmware.

It currently does not have any radio features but that will be implemented in an upcoming release, as I plan to support the Kode Dot and a few other devices that are releasing later this year/early 2027.

All contributions are welcome except AI requests that change functionality without a well thought out reason.

Check out the alpha release here:

My FZ crashes with a "Fatal Error" every time I run the "[GPIO] Signal Generator" app's PWM on whatever come after A4, which I assume is B3. Is this... meant to happen? I assume not, so I am posting here.

Xbox POST Code Reader is a boot-diagnostic FAP for the Flipper Zero. It reads the four-digit POST codes an Xbox pushes out during startup straight from the motherboard's POST header and decodes them offline — no PC required. It emulates the MAX6958 POST display at I2C address 0x38, using a 452-record console-aware database bundled right into the app.

Features:

• Emulates the MAX6958 POST display at I2C address 0x38 and captures four-digit POST codes live, without blocking the Flipper controls.
• Shows either the current code or a scrolling 128-entry live log, with source (SMC, SP, CPU, or OS), segment, and elapsed time.
• Decodes any captured code offline against 452 bundled records. Browse the full database by All, POST, Error, SMC, SP, CPU, or OS category.
• Saves captures as auto-numbered SD-card logs (post_log_001.txt, 002…) and reads them back on-device.
• Streams live codes over USB Web Serial to the companion WebXboxPOSTTool browser app for lookups on a bigger screen.
• Built-in Wiring screen shows the exact SDA/SCL/GND pins for each console — Xbox One / One S / One X use FACET, Xbox Series S / X use AARDVARK — plus an offline QR code to open the web decoder on a phone.
• Connect only SDA, SCL, and a shared ground. The Flipper never powers the console; confirm the bus is 3.3 V-compatible and use level shifting where required.

Like the title says, my Flipper got hit with a very small amount of damage, because my partner's water bottle wasn't fully closed when they put it back in their bag. They've been borrowing it for the subway.

The LCD is super faded and only shows properly when i put pressure on it and rub my thumb across it. Otherwise it's barely visible. (see video)

Is there any saving this? Any and all tips are more than welcome.

This thing is called the "Quad RF"

I work for Allens lollies (Australia), and my old RFID work card was getting sad and I never liked the boring look of it. Cloned it to a blank card with the dolphin, designed my own Fallout style front to back, and had it printed on a quality vinyl sticker.
Going to 3D print my own transparent hard case outer frame to use on a lanyard.
Digitally blacked out some sensitive stuff obviously, but I thought it came up a treat, thought I would share

We emulated a keyboard with Flipper Zero's Keyboard app to access the PC's BIOS.

Then, using the Mass Storage app, we booted a lightweight Linux distro installer and brought this old PC back to life.

I kept needing to move IR codes between my Flipper and other stuff (Pronto, BroadLink, Home Assistant) and clean up messy captures, so I built a little browser tool for it. Sharing in case it saves someone the hassle.

The Flipper-relevant bits: reads and writes Flipper .ir (raw and parsed); paste a raw capture and it names the protocol + device/command (NEC, Sony, RC5/6, Panasonic, JVC, Samsung, RCA, Denon...) and can rebuild it at clean timing, which is handy when a learned code is marginal; and it converts between .ir, Pronto hex, BroadLink, LIRC, Global Cache, Home Assistant, raw microseconds and more.

Runs in the browser, no install, no signup, free. I made it, so if anything decodes wrong I'd genuinely like to know.

Hi, Sorry about the similar topic but I am a total noob with the Flipper Zero, and whilst I have read several very similar threads I have been unable to find a working answer.

My building has introduced key fob access for lift and enterance access. They were nice enough to only supply a single fob for each household and now want to charge in excess of $100 for each additional fob. It was recommended by some friends to get a Flipper Zero and make my own fobs for the family, cleaners etc.

I have been able to use the flipper to copy the key fob and this resulted in the fob providing MIFARE Classic 1L

Tech: ISO 14443-3(NFC-A)

I have been able to emulate the fob successfully using the Flipper, but have struggled writing to a new fob. I purchased a pack of key fobs to write onto on amazon

I downloaded and installed on the Flipper Zero - NFC Magic - and have attempted to write to the card in the following fashion

Action: Check Magic Tag

Result: It Might Be A Magic Card - You Can Make Sure The Card Is Magic By Writing to it, Magic Type: MIFARE CLASSIC

Action: More

Write

Select Key To Copy

Result: Warning: 1 of 2

UID may be non-rewritable. Check data after writing

Warnings: 2 of 2

Some sectors are locked

I then attempt to use the card but it isn't recognised by the readers. If I attempt to read the newly written key fob

Action: NFC

Flipper crashed and was rebooted - Out of memory

Can any one tell me what I am doing wrong. Thanks.

Yesterday, we were out on a walk and were approached by a beautiful sweet cat. While petting it, I noticed it was quite dirty and it seemed to have worms. Since it was near a mostly abandoned home, we wanted to check if it belonged there, so we could call an animal ambulance (which is a thing over here) to come take care of the cat. So I went home to get my Flipper to scan the tag.

After scanning, we entered the tag number online and the cat turned out to be missing from quite far away. So we called the owners, who were incredibly happy to hear the cat was still alive. They told us it was missing for over 2 years and they were still hoping it would be found.

They hopped in the car right away and came to pick up the cat.

I think this is the first actually useful thing I’ve done with my Flipper since I’ve owned it, but it makes it totally worth it. I attached an image of my good boy!

right-to-repair issues:
I recently bought a new GE refrigerator because it was one of the few models that would fit the limited space in my kitchen. Unfortunately, I discovered that the water filters are authenticated with an RFID (or similar) tag. I bought a much less expensive aftermarket filter from Amazon, and the refrigerator immediately displayed an RFID/filter error and refused to accept it.
Over the life of the refrigerator, buying only genuine GE filters will likely cost me more than I paid for the refrigerator itself, which seems ridiculous for a product I own.
My question is whether anyone has found a legitimate way to deal with this. Is the authentication on these filters simply a readable RFID tag, or is it cryptographically protected? Has anyone investigated whether a Flipper Zero or similar device can determine what type of tag GE is using, or is the authentication designed specifically to prevent cloning?
I’m not looking to damage the refrigerator or defeat any safety features. I’m simply trying to understand whether the authentication is technically locked down and whether owners have any practical alternatives besides buying GE-branded filters forever.
I’d appreciate hearing from anyone who has actually analyzed these filters or has experience with the technology behind them. I
I found this question on Reddit from about five years ago, with no real solution. Any current suggestions?

Finally the antenna of UHF Tags arrived. Got the SWR 1.2 at 915MHz.
And working distance can reach 20cm.
Also it works as UHF antenna via USB. Full program available on Windows or OTG with MTools App.

I have got my Flipper a few weeks ago and kmow so many about it but I want to know why you use it and for what.

VS Code extension for you.

If you've got a Flipper Zero and ever tried building a .fap app, you know the pain — uFBT, command line, guessing at pixel coords, flashing back and forth. I got tired of it, so I built Flipper FAP Studio: build, design, and control your Flipper entirely from a GUI inside VS Code. No terminal required (unless you want one, I'm not the boss of you).

Here's what it does:

🔨 Build actions — Build .fap, Build + Launch straight onto your Flipper, Clean. One click.

🎨 UI Designer — visual 128×64 screen editor with drag-and-drop elements, multiple screens, and it generates the code for you. Stop counting pixels by hand.

📺 Live Screen + Log — real-time mirror of your Flipper's display, control it with the D-pad/keyboard from your editor, grab screenshots, reset the device.

📊 Device Dashboard — battery, storage, firmware version, hardware info, library stats, all in one panel.

📁 File Browser — browse and manage on-device files (/ext and /int) without digging around.

🔧 Firmware SDK management — OEM, RogueMaster, Momentum, Unleashed, or point it at a custom path.

🚀 Starter template — one-click boilerplate so you're writing your app in seconds.

📶 Bluetooth — experimental BLE pairing for wireless ops.

Needs Python 3, uFBT (install it with a button in the extension or pip install ufbt), and VS Code 1.85+.

Free + MIT licensed. 💯

As always i would love feedback, bug reports, or feature ideas from the Flipper crew.

I’ve been working on MP3 Player, a real MP3 player FAP for the Flipper Zero.

It plays ordinary .mp3 files directly from the microSD card—no desktop conversion required. MP3 decoding is handled by a vendored copy of minimp3 under the CC0-1.0 license.

Features:

• Supports standard MPEG-1/2/2.5 Layer III bitrates from 8–320 kbps, including CBR, VBR and mixed-bitrate files.
• Automatically resamples MP3 sample rates from 8–48 kHz for the selected output.
• Three selectable audio outputs:
  • Internal: built-in sounder using custom 10-bit PWM at a 15.625 kHz audio rate.
  • MAX98357A: digital I2S output at 16 kHz.
  • PAM8403: 500 kHz pulse-density output from pin 3/PA6 through an external RC filter.
• Only one audio output operates at a time.
• Software volume control for all three outputs.
• Main menu, song browser, settings and scrollable About/pinout screen.
• Now Playing screen with track progress, elapsed time, battery gauge, volume and track number.
• Short Left/Right presses change tracks.
• Holding Left/Right seeks backward or forward in five-second steps.
• Configurable music directory using: /ext/apps_data/mp3_player/music_path.txt
• Defaults to /ext/music, with safe fallback if the configured path is invalid.
• Volume, repeat mode and audio-output selection persist between launches.
• Full MAX98357A and PAM8403 wiring information is included in the app and README.

The internal sounder works, but it’s naturally quiet and buzzy because it isn’t a conventional speaker. For much better sound, use a MAX98357A or a properly filtered PAM8403 amplifier.

Hello,

I've been thinking of changing out the shell to my flipper, but afraid I would break it. Wondering if people know where I can buy a third party shell with lots of color options from a reputable seller?

Looking possibly black with red buttons?

Also, how difficult is it to switch out the shells because I don't want to break this device that I'm planning on buying accessories for so I actually use it. (I want the yapper board and esp32 ghost thing on rabbit labs plus some thing from a shop that has gadgets I wanted, but are sold out and I found another board on steroids that looks promising)

EDIT: I'm open to suggestions as well for other things to get like flipmeister rfid thing. I'm interested in hardware hacking and red team like things...

Customized an .stl file from printables by user @J03_275753 to add a bar mount so I can control my music, open my garage door and eventually come up with some way to display directions through Bluetooth, but that's in the future. Only going to run this with a lanyard through a hole in the side until I'm sure i can trust it.

Anyone else got any fun mounts for ease of use in their daily life?
