It works. It’s free. It doesn’t track you and there are no ads. What a mad lad!!! THANK YOU! ### 5/5 — Elegant and works *2026-06-23, version 1.3.6* It’s better than most of the paid apps with similar features. And it is FREE. ### 4/5 — Best free NDI Viewer *2026-04-05, version 1.3.6* Best NDI viewer I’ve used for apple TV. Only wish I have is a way to disable the source water mark on bottom left of screen. ### 5/5 — Simple and performs *2026-02-14, version 1.3.3* Gets a five star because it simply works. ### 5/5 — Lowest latency NDI viewer I’ve ever used *2026-01-13, version 1.3.2* Best ndi viewer for straight video stream :) ### 5/5 — Amazing to watch external content in 4K HDR *2025-11-21, version 1.3.2* Paired with kiloview n60 and can watch 4K HDR 60fps from PS 5 Pro and 4K blu ray, works amazing. ### 4/5 — Works great, and is free! *2025-05-22, version 1.2.1* NDI discovery and playback works amazing, clear video and low latency, even over WiFi. The only thing keeping this app from 5 stars is the lack of Picture in Picture mode ### 4/5 — Works once per open *2025-04-27, version 1.2.1* It works the first time I launch it. If I try to switch NDI sources, or lock my screen then reopen it, the entire screen is black. I have to force close the app for anything to work again. On first launch, it works great. ### 5/5 — Amazing NDI *2025-03-17, version 1.1.9* I paired this with a zowiebox. I can now broadcast any HDMI signal to my AVP. Great job Chen Zhang! ### 5/5 — Works *2025-03-12, version 1.1.10* Audio de-syncs sometimes. I really wish there was a build for Apple TV, given that the only options on the App Store are rather expensive. ## Frequently asked questions about Vxio ### What does Vxio do?
