It's inconvenient because it pops up every time the window is displayed. ### 3/5 — UI、UX周りを改善して欲しい *2025-11-09* 画質、接続共に文句無しですが改善して欲しいのが ①アプリ起動中にコントロールセンターを出そうとすると強制的にアプリから締め出されてしまう。iPhoneの明るさ調節など出来ない。 ②タップしただけで検索画面に行ってしまうと誤タップが怖い。タップしたら右上にXボタンが出てくるとかにして欲しい ③横向き固定ではなく縦でも使えると嬉しい iPhone 12 mini iOS 18.5 ### 4/5 — Works for me *2025-02-23* One feature to make it perfect: Background play. Keep playing when screen is off! 😀 ### 2/5 — O som parou de funcionar *2025-01-17* Me deixou na mão, o áudio parou de funcionar e não é meu dispositivo, pq nem no iPhone nem no iPad o áudio é recebido, precisei comprar outro app **Developer response:** Hello Kohjac Will Make sure you device is not in airplane mode. if you continue to experience a problem please contact our support by email. ### 3/5 — Funktioniert - aber mehr Features wünschenswert *2024-06-03* Also an sich macht die App ja was sie soll und das auch sehr zuverlässig - deshalb sollte Mal eigentlich zufrieden sein. Aber: Seit Ewigkeiten stützt die App jedes mal ab wenn man das Kontrollzentrum öffnet - das ist echt lästig. Außerdem wären einige kleinere Features wünschenswert. - Wiedergabe im Hintergrund - speichern der aktuellen Wiedergabe (dass nicht bei jedem öffnen das Signal erneut angewählt werden muss - UV-Meter - Anzeige von tech. infos zum NDI Signal wie Format oder Statistiken zur Übertragung Es würde mich freuen wenn es hier zu ein paar Updates gäbe! ### 2/5 — NO Audio-Disappoint *2024-03-29* Video quality is good but I can’t get the audio. Disappointed. **Developer response:** Hello Hejar berenji Make sure you device is not in airplane mode. if you continue to experience a problem please contact our support by email. ### 3/5 — Can not receive as portrait window *2024-01-13* 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 ### 2/5 — Works on ipad. Audio doesn’t work on iPhone *2022-01-31* Beta app at best Things work on ipad but not refined No audio on iphone App crashed into a loophole ### 2/5 — Very crashy *2021-09-10* 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 app. **Developer response:** Hello lightbord As you suggested yourself, using a lightning to ethernet adaptor will likely make all the difference to you. Also turning off hi res will reduce the bandwidth requirements and enable you to use the app with noisy wifi. ### 3/5 — Please support Rec.2020 HDRs Viewing. *2021-08-31* Hi, good app. Please support Rec.2020 HDRs Viewing. ### 2/5 — 入力はできました。 *2021-08-17* 高帯域での入力に対応していません（画質が酷い） 対応してるのかもしれませんが、やり方がわからないです… **Developer response:** こんにちはプラスクラブとかシラネ [システム設定]-> [アプリ]-> [NDIモニター]でHiResとRetinaを有効にできます ### 4/5 — Much improved *2021-08-08* 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. ### 3/5 — About Apple new M1 CPU *2020-12-16* Hi, I’m going to buy a new laptop which has Apple new M1 CPU, my question is does this NDI app support Apple’s silicon chip M1 already? ### 3/5 — A great start, but could be much more *2020-11-09* 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. ### 3/5 — Great Potential *2020-10-26* 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 **Developer response:** Hi Ultan21. Perhaps your NewTek ScanConverter is emitting NDI at a higher resolution than the app can support. Try sending HD from ScanConverter and check if that works as expected. If you continue to experience issues with audio please contact support so we can investigate. ## Most critical reviews (10 lowest-rated) ### 1/5 — Simply does not work at all *2026-08-10* Mid streams appear, but when you tap them, they do nothing at all. The app just returns to the holding screen. Do not waste your money ### 1/5 — No audio *2022-12-09* No audio in app at all - all ndi tested - full ndi, ndi hx2 and ndi hx3 Ndi hx video only supports h264 at 8 bit 4:2:0, no support for 4:2:2 or 10 bit, and h265/hevc gives a codec error for both ndi hx2 and ndi hx3 Using iPhone 13 Pro Max **Developer response:** Hello PTRJAY Please visit the troubleshooting guide at http://www.sienna-tv.com/ndi/support.html and contact support if you continue to have problems ### 1/5 — 可以退款吗？没画面啊 *2022-04-11* 可以退款吗？没画面啊 **Developer response:** Hello 眼睛疼也 Please contact our support for help ### 1/5 — Low quality pure crap BAD BAD BAD *2022-02-25* Top Price for low quality. Its about 360p. Very jaggy edges. M’y Wifi is very good it’s not the problem. **Developer response:** Hello imedia123, your app is probably set to view the proxy stream If you want full resolution, visit the app settings and turn on Hi Res. Very simple solution. ### 1/5 — I phone 12 pro max *2021-04-28* Reverse picture with Iphone Pro Max ### 1/5 — NDI Display *2020-07-16* This is an overpriced display. I could have used the NDI cameras IP to display for free. Was hoping for the ability to control at that price. Has NO control options. A huge disappointment. ### 1/5 — Doesn’t work. *2020-06-22* Black screen. Audio is fine tho... **Developer response:** Hi Djsky123 Please visit the troubleshooting guide at http://www.sienna-tv.com/ndi/support.html and contact support if you continue to have problems. ### 1/5 — Shows no video at all *2020-06-04* I choose the stream in the list but nothing shows. **Developer response:** Hi Sbikofsky Please visit the troubleshooting guide at http://www.sienna-tv.com/ndi/support.html and contact support if you continue to have problems. Most issues like you describe are due to firewall on the sender. ### 1/5 — Just goes black on my iPad *2020-03-13* How do we get our money refunded? It isn’t working on my latest iPad. It just goes black screen. **Developer response:** Hi Marysol1901 Please visit the troubleshooting guide at http://www.sienna-tv.com/ndi/support.html and contact support if you continue to have problems. ### 1/5 — Ndi 拉取画质模糊 *2019-12-11* 信号观看特别模糊有种480p既视感，没有任何参数可以调整 **Developer response:** 你好shefirtwins 请参阅“设置”应用程序-> NDI监视器->高分辨率NDI和Retina显示，这将使您提高分辨率 ## Most praised reviews (10 highest-rated) ### 5/5 — Works as intended *2025-09-10* Works as intended in iPad Air 2 OS 15.6. Delay on 5Ghz Wi-Fi is around 200-500ms, almost seamlessly. ### 5/5 — Simple and effective *2024-08-13* This is the lowest latency NDI monitor that I’ve found. It’s noticeably quicker than Top Director. However, Top Director is significantly more feature rich. ### 5/5 — Best NDI monitor I’ve found *2024-02-07* This app does an excellent job of finding NDI sources and of playing both NDI audio and video. Highly recommended! ### 5/5 — Simple and easy use *2021-12-12* Last NDI framework update was a little slow coming but got this app working again. If you use NDI this is a handy app to have. ### 5/5 — 不能全屏啊 *2021-11-26* 如何才能设置他全屏啊 ### 5/5 — Easy connect, monitor your NDI feeds *2021-10-18* Finds and displays all available NDI feeds. Note- on some iPhones with silent switch on side, silencing the ringer will also silence NDI audio. ### 5/5 — Great monitor, though more features would be great *2021-09-15* Worked straight away on my iPad, although would be great if you could zoom in on the source to see more detail and to fill the screen. Recording would be a great option too ### 5/5 — Stable, Production ready *2021-09-01* Very stable and prod-ready monitor solution. It requires very-high bandwidth capability under non-HX codec. It should be stable with WiFi6 or wired connection. Otherwise I had to untick "Hi-Res Video" setting for stability. ### 5/5 — Perfect! *2021-02-21* Thank you for that great software. It works really good with vMix or even the NDI iPhone Cam app. Its so cool to have a iPad as a other screen to use it as teleprompter! ### 5/5 — Great *2020-07-11* Works easily. Although appears not to scale content correctly (screen share from iPhone is squashed on iPad) --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
