In this video, I demonstrate how to stream/cast your iPhone screen directly into Meta Quest 3 using Tendy Link and Tendy!
To show its real-world capability, I connected a Wi-Fi digital microscope to the iPhone and streamed the live microscopic feed straight to the Quest 3 headset. Watch as we inspect a NT$1000 banknote in ultra-high detail and uncover hidden security features—including micro-printed "1000" numbers hidden in the mountain image! 🔍💸
🛠️ Setup & Network Configuration
📱 1. App Downloads & Pairing
iPhone: Download Tendy Link
Quest 3: Download Tendy
Casting Steps:
Open Tendy on Quest 3 and click "Start Receiving" to display your IP address.
Enter the IP address into Tendy Link on your iPhone, then tap "Start Casting".
Select Tendy Link for screen broadcasting and tap "Start Broadcast" to mirror your screen!
Since the iPhone needs to connect to both the Wi-Fi microscope and the Quest 3, you MUST turn on iPhone Personal Hotspot and connect your Quest 3 to it. This ensures both devices are on the same local network while streaming.
Standard Screen Mirroring (No external Wi-Fi accessories):
If you are just casting the iPhone screen normally without connecting to another Wi-Fi device, simply connect both your iPhone and Quest 3 to the same Wi-Fi network. No hotspot required!

Turn Your Meta Quest 3 into a Giant DJI Flight Display! 🚁 (DJI Neo + Quest 3 Immersive Flying)
📌 Video Description
In this video, I'll show you how to wirelessly display the DJI Fly app on your Meta Quest 3 using Tendy.
Simply install Tendy Link on your Android phone, and you can stream the DJI Fly screen directly to the Tendy app in Quest 3. Instead of flying while staring at a small phone display, you can enjoy a large virtual screen inside your headset for a much more immersive flying experience.
No expensive flight goggles are required—just your Quest 3 and an Android phone.
💡 How It Works
🕹️ DJI Fly remains in full control. Your flying workflow doesn't change. Continue flying with the DJI Fly app using the touchscreen or, for the best experience, a DJI remote controller.
🥽 Quest 3 becomes your giant virtual display. Tendy Link wirelessly mirrors your phone's screen into Meta Quest 3, allowing you to fly while viewing DJI Fly on a large floating display.
🌐 More than DJI Fly. Screen casting is just one of the many features supported by Tendy Link. You can also mirror many other Android apps to Quest 3.
⚠️ Important Notes
This solution uses wireless screen mirroring, so a small amount of latency is normal.
It works well for casual flying, hovering, aerial photography, cinematic shots, and flying in open areas.
It is not intended for high-speed racing, freestyle FPV, or flying through tight obstacles, where ultra-low latency is essential.
This is not a replacement for DJI's dedicated flight goggles, but an affordable way to enjoy flying on a giant virtual display.
A lot of people have been searching for a way to cast their phone screen to Quest 3.
Honestly, so was I.
As a drone pilot who loves FPV, I had one simple wish when I got my Quest 3: I wanted to fly my DJI drone while wearing the headset, putting the live camera feed right onto a massive VR screen.
I searched everywhere but couldn’t find a smooth, reliable solution that worked for me.
So, I did what any developer would do—I built one myself.
That’s how Tendy Link (Phone Cast) came to life.
But to be completely honest, once I finished coding it and started testing, I realized its potential goes way beyond what I initially imagined. It’s not just about checking notifications or watching YouTube anymore. The real magic is: It brings the entire Android ecosystem seamlessly into Quest.
My mind is already racing with all the fun things we can do with this:
🔹 Flying a drone with DJI Fly inside Quest 3 (Next video topic!)
🔹 Driving FPV RC cars with a giant VR viewpoint
🔹 Hooking up a digital microscope for massive macro visuals
🔹 Doing close-up cinematic camera movements with Gunpla models...
I truly believe that sometimes the best projects don't come from market research—they come from a pure desire to play and experiment.
If this tool that I built just for fun happens to help other Quest 3 players who share the same pain point, that makes it even better.
This video is a quick walkthrough and submission demo of Tendy Link's vertical and horizontal casting modes. The app is currently going through the review process!

In the next video, I’ll be dropping a full hands-on feature of the "DJI Fly VR Big Screen" experience! If you want to see what it's like to fly a drone inside Quest 3, make sure to subscribe and hit the notification bell so you don't miss it!
