## Flight Test X20 Reviews in United States

### ***** "Wish there was more than 5 stars."
It doesn’t get simpler than this. You follow the instructions. You pass the test. Just buy it you wont regret it. I just passed my FOI today with 96% using shepherd.
-- juice duce, 2024-12-03

### **--- "Content very effective, app needs work"
As others have noted, Sheppard is a good test prep service, but the app would benefit from some updates. If you switch to another app, even for a second, it closes and has to reload. It is good about saving progress so it’s merely annoying, but it is pretty annoying. And accessing figures and explanations requires chasing content back and forth across the two halves of the screen.
-- Jordan Schooler, 2024-10-15

### ***-- "Great material, lousy app"
Utterly inexplicable that someone could put this app out there. Terrible app. Shuts down if you dare open another app, such as the PHAK. If you are in a practice test and open a different app, it will close you out, update for the 15th time in your study session, and you miss out on checking your answers. 

The questions are the identical to the ones on the writtens. 

Please please PLEASE update this app before I don’t need it anymore.
-- Black Shotzy, 2024-08-01

### *---- "The app is terrible - not Sheppard Air"
I used the old app for Commercial and didn’t have many problems with it. However, since starting FOI and FIA, I’m having a ton of problems with the app reloading itself whenever I switch pages. I was almost through a practice test when I received a text. I replied to the text and came back to the app. The app reloaded itself and I lost my test. I even lost all the questions I had marked to review along the way. This happens a lot when going through the study materials but isn’t that annoying because it saves your progress. The tests don’t save your progress and are completely deleted once you are done. This is a major design flaw.
-- oSICKNASTYo, 2023-12-09

### *---- "Great Service, Horrible App"
Shepherd air is great and their study method really works, but the app is clunky and outdated. Every time you go home or switch to another app is has to redownload the data and takes you to the main menu. It crashes every few questions, requiring you to do the same thing. The computer version works much better.
-- sw4gdaddy, 2023-10-18

### *---- "Review of App, Not Sheppard Air"
Sheppard Air is an excellent resource for studying for your written exams, however, the app is a complete failure in simple programming. I’ve had to change my iPad’s sleep settings to never let me iPad go to sleep, just so that the app wouldn’t crash. If you accidentally touch a corner that switches app, the app will crash. If you overlay a note taking app or try to split screen, the app will crash. If you accidentally swipe up to take you back to the home screen, sometimes the app will crash. Resuming your studying is no big deal but in a practice test you have no choice but to start over. I have restarted more practice tests than I have completed due to the app crashing, about 70%. This has happened on all 3 separate exams preps I have bought from Sheppard Air.

It has also been a while since the app itself has been updated and it is in desperate need of an update. Sheppard Air itself is great, but this app nosedives into awfulness worse than the MCAS incidents on the 737 MAX. The app is a waste of your precious time.
-- TechyMark, 2023-08-15

### ***** "Worked for me"
Studied for about 6 hours just as the course outlined. Got a 100 on my test for MCN.
-- spencer strange, 2023-07-21

### *---- "Good study material on awful software."
I have lost progress on many practice tests due to the app kicking me back to the login screen. For how much money I paid for the course I expect better.
-- I-am-glory, 2023-07-04

### ***** "Great app to get 90% pass rate"
I just passed my commercial written to 94%. Study strategy which works. Thank you Sheppard. 

Please hire UX designer to fix app. Good interface does not require long explanation with steps, student should follow intuitive. Just don’t give lazy idiots to go to tests before learning steps.
-- sergattic, 2023-06-17

### ***** "Result explains everything"
I attended the IRA test and get 100%, 5/5 stars. The result explains everything
