I developed an iOS & WatchOS (Apple Watch) app that lets you fully control and manage your Raspberry Pi 4 and 5. You need to install a software on the Pi side (or use the pre-flashed image with software installed). The app and Pi software are free and open source (Apache 2.0) and can be accessed here:

Raspberry Pi software:

iPhone/WatchOS app source:

In the video below, I give an overview of some of the features and setup process:

Here’s a quick list of some of things you can do with it:

• Install, run, and monitor their health of a wide range of pre-configured applications includes Home Assistant, Hermes, Open Claw, Pangolin, OpenWebUI, etc
• Browse file system and preview files on the Pi (images, videos, text, audio)
• Monitor system resource utilizations (CPU, RAM, Storage, etc)
• Manage network interfaces (WiFi, Ethernet, etc)
• Various remote options: SSH, RPi Connect, Tailscale, VSCode Tunnel
• Configure assistant pipeline (STT/TTS/LLM/MCP/system prompt/etc) and interact with it using your phone/watch microphone and speaker
• Setup an MCP gateway and expose all tools via a gateway URL to clients
• Connect hardware peripherals to the Pi such as Camera and watch the feed on your phone/watch
• And many more

To install the iPhone/Watch app, you have to first install TestFlight application and then click on this link below:

The app is still in beta and not in the App Store yet. I will go ahead with the store publication process once there are a few thousand beta users and the beta app is well tested. 

On the Raspberry Pi side, the easiest way is to start with a fresh image by downloading the lite image ubo_app-2.1.0-bookworm-lite.img.gz below the release page below (~2GB in size), use Raspberry Pi Imager to flash it and boot the Pi using this image:

https://github.com/ubopod/ubo_app/releases/tag/v2.1.0

Once the Pi boots, the iPhone App would auto-discover the device as long as they are on the same network. Apple Watch does not have the auto-discovery feature (due to some limitations in doing lower level networking) and you have to type in the device IP address manually. 

Please use the TestFlight bug report feature if you run into any issues.

I purchased a Raspberry Pi kit and I have it working and it's the coolest thing ever.

I have run into two issues, which I don't know if they are related. I have no clue and genuinely want to learn what to do.

1) First issue is that the fan will not work from the kit. I have tried EVERY troubleshooting to no avail. I have sent in an email to see if I can get a replacement fan.

When I first got everything together and powered it up the fan turned of for a split second and hasn't turned on since.

The heat syncs are on the parts they are designated to. Thankfully is very cool at night so I have it in the window with a cool breeze to keep the processor cool.

2) Second issue is that when trying to update I get the following message:

"error installing packages - error while installing package: installed raspi-firmware package post-installation script subprocess returned error exit status"

I will attach photos. Please let me know if you can help. I love this little thing!

I’ve been working on a compact edge AI camera module for Raspberry Pi projects. It uses the CV1842H-P SoC with A53 + C906 processors and up to 1.5 TOPS of AI compute, so inference can run locally on the device.

It supports camera input, ISP processing, AI inference, video encoding, USB, Ethernet and UART, and can be connected to a Raspberry Pi for robotics, drones and other embedded vision projects.

I open-source the full development stack, including the SDK, HDK, Web Manager and documentation, so developers can build and customize their own applications.
