I had to download a program to sync my laptop with the IPAD but I am unable to install it to my laptop, saying something about sxstrace.com error message. My laptop’s OS is Windows 7. ### 3/5 — Cant connect *2018-05-15, version 1.6* I got the app and software installed it says it is connected but cdu remains dark doesnt show anyhting? ### 4/5 — Works well after sorting out issues *2017-10-01, version 1.5* Make sure to check the PMDG ini file for setting the SDK broadcasts. Seems like if you add this after other apps it edits the file and added a second SDK header. That caused none of the screens to show. Only caught it as other add ons that also previously shows data no longer worked either. After editing the file again and removing the extra header all was good. ### 1/5 — Never loads... *2016-09-18, version 1.0* Do I have to pay for apps which takes a day to initialize?? Give me my money back... ## Most critical reviews (10 lowest-rated) ### 1/5 — Useless product *2024-05-20, version 1.91* Always crashes and unresponsive if the author is not supporting this product he should take it off market! ### 1/5 — Close but not complete *2022-04-19, version 1.91* No text is visible but buttons work ### 1/5 — Unreliable *2022-02-04, version 1.91* This app is very unreliable. It works well ONLY when it works which is once every million time you try to use. This is waste of money ### 1/5 — Terrible. Not worth a penny *2021-06-09, version 1.91* I spent $7 on this and was able to connect with no issues. However nothing shows on the screen and the buttons on the app don’t match the buttons on the MCDU in game so I press menu and it brings up the fix screen I game etc. As I said nothing shows up on the screen on the app so you have to look at the computer anyway to see what your doing. Absolutely defeats the purpose and is a total waste of money. ### 1/5 — Waste of money *2020-11-02, version 1.91* Extremely complicated to make it work. I have not been able to use the app on the iPad. Waste of money. ### 1/5 — Waste of money *2020-08-06, version 1.9* Looks good on the apple store, but don’t be fooled. Not true images. Sure you get a fmc on your apple device, but no text in the box, you have to use the PC screen to see what the buttons do. Sorry I donated $13 for a useless piece of app. ### 1/5 — Just doesn’t work *2020-03-30, version 1.9* So I bought this and opened it for the first time and just dident work takes you to a page for a link and it just doesn’t work. Would not recommend do not buy ### 1/5 — Save your money *2019-12-01, version 1.6* It just doesn’t work , and no answers to my emails ### 1/5 — Setup easy but... *2019-07-12, version 1.6* So it’s all connected and looks great, but whatever I type on the CDU is duplicated - so if I type EGKK in the scratchpad it comes out EEGGKKKK? Can you help? This will be awesome when it’s fixed though ### 1/5 — Cannot get the app to work *2019-07-12, version 1.6* I can’t get the app to work going to request my money back. Should be a simple download and use app like every other app I’ve ever used before. ## Most praised reviews (10 highest-rated) ### 5/5 — Great App *2021-05-04, version 1.91* I recently downloaded this app and it’s associated PC software and I am delighted with it. I have used it on PMDG 777, 747 and 737 flights and they all worked perfectly. It was easy to get connected and operational, no problems at all. I would highly recommend this app to any PMDG user. Cheers ### 5/5 — Great app but... *2020-05-21, version 1.9* I was using this app for about a month and suddenly today the app doesn’t work properly I get no image on the iPhone If I open the Cdu in the sim it does receive the input but I see nothing in the iPhone ### 5/5 — Great App *2019-12-15, version 1.9* All keystrokes respond no more mouse great app to use with Ipad or phone. Customer support has been responsive and helpful. Price is competitive. Update to PMDG 737NGX u was free and done quickly. ### 5/5 — Could be good *2019-03-06, version 1.6* After the issues I was having with this app caused me to write e negative review, I take it all back, the app works perfectly and the author is just brilliant, you have a problem and he will get back to you within a couple of days, do not buy the other expensive FMC apps on here as this one is perfect 👌 ### 5/5 — Great App! *2018-01-21, version 1.5* I love this app! Great and easy to install and use. Makes it really nice not to have to pan or open up the CDU. Fast connection and little work to set up. Worth the price! ### 5/5 — Brilliant *2017-12-20, version 1.5* This app is brilliant to use! ### 5/5 — Now compatible with P3D V4! *2017-11-01, version 1.5* Glad the app has been updated. It works great and I've been using it for most of my flights in the simulator. Much easier to setup too. ### 5/5 — Works with P3Dv4 *2017-09-20, version 1.5* I just flew 5 legs with is App. Everything works as advertised. Be sure to read the setup document and follow the order exactly as it's written. If you miss a step you will likely end up with a black screen. All functions seemed to work fine. Blue Sky's! ### 5/5 — Lovely *2017-08-07, version 1.5* Works wonderful highly recommended for any flight simmers ### 4/5 — Great app *2022-06-01, version 1.91* I love this interface and use it often, well I did until PMDG’s B737 for MSFS. Is there any chance of this app being available for MSFS? --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
