NDI sources on your local subnet are presented in a pop up menu to select, when you tap on the screen. If you enter additional 'NDI Access' IP Addresses from other subnets into the system prefs panel for NDI Monitor, those NDI sources may also be accessed. Includes support for NDI Discovery server (see app settings), resolution control, video flip for autocue and control of NDI network Protocol for reliability. A preference allows 9x16 streams to be shown in portrait mode for social media production workflows. Notes: A very stable WIFI connection, or a wired ethernet connection are required for smooth playback of NDI Streams. Using a directional WIFI antenna and using the sweet spot of your wifi can help. If you experience glitching of audio or dropped video frames, the problem is very likely a wifi connection which is insufficiently stable to support smooth NDI video to iOS - in this case please try a wired ethernet to lightning adaptor. You should not expect perfect performance when selecting Hi Resolution NDI - which is offered as an experimental mode for users with very fast devices, on very fast, clean network connections. In some cases you may see great results in hi res. There are preferences in the System Settings app for NDI Monitor to setup application options. You can also use the app NDI Scanner as a stream selector - it will open NDI Monitor when you click on a selected stream. You can also now set the NDI Device name, required for multi device operations with iOS17 NB. This app does not support NDI | HX1 format streams - only NDI full bandwidth format or NDI HX2/3 Set the "NDI Device Name" in the app settings if you are using multiple devices on the same network - to give them unique names. ## NDI Monitor Screenshots - [Screenshot 1](https://is1-ssl.mzstatic.com/image/thumb/Purple113/v4/86/9c/82/869c8234-4223-beeb-0a89-7d31b885cd64/pr_source.png/2688x1242.png) - [Screenshot 2](https://is1-ssl.mzstatic.com/image/thumb/Purple123/v4/d2/c1/43/d2c14350-aca4-61dd-e495-ce9b1451aa7d/pr_source.png/2688x1242.png) ## NDI Monitor Rating Breakdown in United States - 5 stars: 10 (37%) - 4 stars: 4 (15%) - 3 stars: 3 (11%) - 2 stars: 3 (11%) - 1 stars: 7 (26%) ## NDI Monitor Reviews in United States ### ***** "Best NDI monitor I’ve found" This app does an excellent job of finding NDI sources and of playing both NDI audio and video. Highly recommended! -- DaleBru, 2024-02-07 ### ***-- "Can not receive as portrait window" Works to receive well, but can only view any source in landscape even if the source is portrait. It gets fit to window to yield big black bars on the left and right of a smaller portrait window -- NEWPVizzies, 2024-01-13 ### **--- "Works on ipad. Audio doesn’t work on iPhone" Beta app at best Things work on ipad but not refined No audio on iphone App crashed into a loophole -- matthew b cho, 2022-01-31 ### ***** "Easy connect, monitor your NDI feeds" Finds and displays all available NDI feeds. Note- on some iPhones with silent switch on side, silencing the ringer will also silence NDI audio. -- dm4321, 2021-10-18 ### **--- "Very crashy" Once you enable Hi-Res NDI and Retina in settings, it looks halfway decent (those should be enabled by default, or at least you should be told that it will look like garbage until you do that). To those saying the audio doesn't work, I've discovered you cannot have your device in silent mode for it to work, unlike several other apps that show video or make noise. It freezes and crashes quite a bit. I found any time I switched sources, it would either crash or freeze requiring a full close and re-open of the app. Though, half the time, when closing the app, it'll crash itself, meaning if I switch to another app for a second and come back, it'll have crashed and I'll need to select my source again and wait the sometimes 30, even up to 45 seconds for it to reconnect to my source, if it does at all. I also find it randomly crashes, such as when getting a system-wide alert, or sometimes even when getting a notification from an app. Swiping down and opening control center (even just beginning to swipe down, by accident, and not opening it all the way) will also result in a crash, similar with pulling down to see your notifications in Notification Center. It also requires a fairly new device to keep the stream going. The preceding thoughts were written based on my experience using it on my iPhone XS Max. When it tried it on my iPad Air 2 (admittedly an old device but it still holds up to other tasks and even some games quite well), the stream was very jerky and the audio cut out a lot, eventually causing the app to crash. It should be noted the two devices were in the same physical location, which is quite close to the Wi-Fi access point, and gets a very respectable amount of bandwidth in iPerf tests on both my phone and iPad. I have not tried wiring the iPad (or my phone for that matter) in with the USB-Ethernet adapter + lightning camera connection kit, but I'll give it a shot. I suspect it won't help the stuttering and jerkiness on the iPad, though. Overall, I'm disappointed with this app and wish there were alternative apps available. The only reason I'm giving the app 2 stars is because it does actually receive and show NDI and audio (most of the time, anyways). It's interesting, because I quite frequently use the Sienna NDI Monitor app on my Mac, along with a few of their other NDI tools (I actually prefer their NDI Monitor over NewTek's), and would have expected more from them in an iOS app. The app is very much not worth the $9.99 I spent on this ap -- lightbord, 2021-09-10 ### ****- "Much improved" A great app for monitoring our livestreaming PC without much delay! The app is much improved with the new version's auto relaunch of your last used source. -- CJD102, 2021-08-08 ### ***-- "A great start, but could be much more" This is the only app out there that does what it does, so it’s hard to make comparisons. The basic functionality works fine — it detects and displays NDI a/v streams. Sometimes the video freezes when switching between apps and requires an app restart, but usually reselecting the source will reset it. Where it falls down are the little things that you expect to work but don’t. The audio output won’t play over Bluetooth, so you can’t use wireless headphones or speakers. The app hasn’t been built with iPad multitasking support, so you can’t do side-by-side mode or picture-in-picture, which would be really useful if you’re monitoring a stream that you’re controlling with another app. For the price, a little more polish would be nice, but until there’s some competition, I don’t know if we’ll see it. -- Wyrdebeard, 2020-11-09 ### ***-- "Great Potential" Works great however having issues with audio (no audio seems to play) and newtec scan converter seems to crash it. Could be a great tool if issues addressed. Iphone Xs Max iOS 14.1/ Mac Book Pro/ Google Wifi AP -- Ultan21, 2020-10-26 ### ***** "Works, but" App works as described. But it can be difficult to exit app and it will not auto rotate. Tried emailing support, never heard back -- mdwill1, 2020-07-01 ### *---- "Shows no video at all" I choose the stream in the list but nothing shows. -- Sbikofsky, 2020-06-04 [View all NDI Monitor reviews and detailed analytics on AppTail](https://app.apptail.io/signup?utm_campaign=ai-crawl&utm_content=reviews) ## NDI Monitor Store Rankings | Chart | Country | Category | Rank | |-------|---------|----------|------| | Top Paid | Thailand | Photo Video | #45 | | Top Paid | Czechia | Photo Video | #185 | ## NDI Monitor Available In -
