This app either doesn’t do it, or does it wrong. Additionally it directly stole NewTek’s logo, which is not cool. It misleads potential users. ### 1/5 — Does not work on iPhone 12 Pro MAX *2021-11-28, version 1.0* Does not work! ### 1/5 — Has anyone got this working? *2021-10-07, version 1.0* Can’t see any NDI feeds that I know are there. What’s the trick to make it work? ### 1/5 — Why is this even on the App store? *2021-09-29, version 1.0* This app connects to nothing. If you enter an IP, it tries port 0 by default. NDI uses port 5961. You can’t configure a port in the app. ### 1/5 — NDI Source not showing *2021-09-24, version 1.0* I tried looking at my ndi source and nothing shows up and if I enter the IP address it just says error very non useful piece of junk ### 1/5 — Doesn’t work *2021-07-31, version 1.0* I can’t get this to see NDI video feeds or test cards. But laptops on the same network running the NDI viewer can see them so I know they’re broadcasting. ### 1/5 — Can’t get working *2021-07-07, version 1.0* Doesn’t work over our network ### 1/5 — It just do not Word *2021-04-30, version 1.0* Do not see any NDI Channel that work with ndi studio on PC ### 1/5 — Does not find NDI sources *2020-12-24, version 1.0* When other viewers work on the same network, this one does not. Tried on both iPhone and iPad. All networking is correct. ### 1/5 — Retracted *2020-08-27, version 1.0* Retracted ### 1/5 — Not NDI, or very outdated protocol support *2020-08-24, version 1.0* I don’t know what protocol this uses, but it isn’t NDI (or if it is, it is limited to the old-style, pre-HX NDI). It can’t see any of the NDI sources on my network, and when I point to my TBS 2605, it shows a 404 error page like it is trying to hit the web server on the device instead of talking to it via the NDI protocol. ## Most critical reviews (10 lowest-rated) ### 1/5 — Scary *2025-01-12, version 1.0* This was randomly downloaded on my phone? ### 1/5 — Does not work *2024-11-26, version 1.0* Cannot connect to any NDI feeds ### 1/5 — Garbage *2023-12-28, version 1.0* Does not work like all their other apps. ### 1/5 — Does not work *2023-12-09, version 1.0* Does not work at all. Bought NDI monitor for $10 and it works perfectly, so I know there is nothing wrong with my setup. ### 1/5 — Should be removed *2023-08-08, version 1.0* Doesn’t discover my cameras… I’m just trying to find the best NDI monitor and can’t even test this one. Other apps work right away so I’m not sure what the problem is, it’s not my network config. ### 1/5 — I wish it worked *2023-03-20, version 1.0* Looking for a simple NDI monitor. Unfortunately this doesn’t work. No sources found and specifying them manually also doesn’t work. ### 1/5 — Can’t connect to my camera *2023-01-10, version 1.0* It automatically assumes the port is zero, and it won’t let me change it. This prevents the app from connecting to the camera. Seems like NDI started working on this app, and then stopped before they were done. ### 1/5 — Trash *2022-08-16, version 1.0* Have not once been able to get to work. Such a good idea but never worked ### 1/5 — Same gripe - I can’t see a thing *2022-05-22, version 1.0* Other NDI apps work fine on my iPhone. This one doesn’t find any of my devices. Not sure what the deal is, but it’s not usable for me. ### 1/5 — Needs updating *2022-03-10, version 1.0* Does not see NDI sources on a network that other apps can. ## Most praised reviews (4 highest-rated) ### 3/5 — Good but *2025-01-28, version 1.0* no zoom controls. But it has ptz controls. ### 2/5 — It works, sort of *2021-08-08, version 1.0* So, it can’t auto-discover since my cameras are hardwired and my phone is on WiFi. If I enter the camera IP address it connects. I can see the a video stream. But, it won’t control the PTZ, except for Home and presets 1-3. No other preset buttons work and the arrows don’t work. There are no zoom buttons either. Pretty sad that the company that maintains the NDI spec can’t write software to control cameras which follow that spec. ### 2/5 — Not working for us *2020-10-15, version 1.0* Just says ‘connection refused’ ### 2/5 — Doesn’t support NDI|HX *2020-08-08, version 1.0* Could be super useful but doesn’t support ndi hx so it doesn’t detect my AIDA NDI PTZ cameras. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
