I really like how there are multiple sections and helped me work from getting familiar with the content to learning and understanding it all. My favorite part would have to be the study section where it gives detailed explanations on the selected answer as well as why the other answers aren’t correct. I would highly recommend this app to anyone looking to pursue a career in dispatch. ### 5/5 — Helpful prep for upcoming 5-week *2023-07-02, version 2.1* No ads, clear and easy format within the app. Good understanding of what I need to study for the ADX test. ### 5/5 — Everything you need for ADX *2023-06-20* Great app, everything you need in one place to pass the ADX. I used the quiz mode mostly to memorize the question answers, and the study mode for instructions on graphing and book problems. Passed on first attempt! ### 5/5 — Awesome Study Tool *2023-04-11, version 2.1* The study and quiz modes are extremely helpful. Then using the test mode to give you a basis of where you truly are is wonderful. Highly recommend buying this if you are attending Sheffield or prepping for the ADX! ### 5/5 — Great ADX study tool! *2023-02-08, version 2.1* Don’t hesitate to purchase this app when preparing for the ADX. It is comprehensive and extremely easy to navigate. The app is by far the most important resource I utilized to help me pass the exam. ### 5/5 — Really helpful *2023-01-07* This app is easy, organized, and helpful. Instead of having multiple pages open on a computer, you have everything in one easy app. It makes it easy to study anywhere. I have yet to take the ADX test but feel confident because of the practice tests and mock tests. ### 5/5 — This app is the reason I passed the ADX test! *2022-12-16* I simply love how user-friendly and accessible this app is. Since I downloaded it to my iPhone, I had so much information at my fingertips at all times. I could study at the grocery store, while waiting at a restaurant, while at the doctor’s office, while waiting in line for a car wash, etc. The begrudgingly slow mundanity of daily life tasks became productive because of this app. I solely used this app for studying and did not access other materials. I recommend taking the simulated realistic 80-question practice tests generated within the app to gauge how well you might perform on the test. Once you consistently score 80-85%, you are ready to take the test. I personally experienced an 8% margin between my predicted score and my actual score, so the projections are pretty accurate. I would recommend this app to any friend or acquaintance looking at a future in flight dispatch! 🛩🛫 ### 5/5 — Good app *2022-09-20, version 2.1* The app has a lot of information to study for the ADX test. There is explanation for each question to help with studying. The quiz and exam simulator are very helpful to practice too. I would recommend this app to anyone who needs to take the ADX. ### 5/5 — Great app. Crashes on me now. *2022-08-02* I’m about halfway through the study topics and have been enjoying the structure of the app. It’s a great app! It’s now crashing on me every time I push the “begin study” button. Giving it a five stars because it has been very helpful. Would like to get this rectified if possible. **Developer response:** Thank you for your review. The app went down for approximately a week. We answered concerned emails immediately and reported everything to the developer asap and they rectified the issue and updated a few "techno items." We also offered web access to those who had an app delay. All has run normally as usual since the issue. ### 5/5 — ADX Test Prep *2022-07-02, version 2.1* This app was very beneficial helping me knock out my ADX before school started. Works great and easy to use. Well worth the money!e ### 5/5 — Great study prep tool! *2022-06-28, version 2.1* This app has immensely helped with my knowledge of the ADX topics. ### 5/5 — Very useful study tool *2022-06-18, version 2.1* The Sheffield ADX Prep app gives me full confidence in taking the ADX.

The App is so easy to use and simple. I am amazed at how well all the topics are covered .This is one of the reason I chose Sheffield School of Aeronautics. ### 5/5 — Prime Tool for ADX Prep *2022-03-23, version 2.1* The Sheffield ADX app is a versatile tool when preparing for the ADX. The content is constantly updated, and insights into the inner workings of the ADX are presented. It is a massive undertaking to take this exam, and the material is presented in-full. The quiz mode is good for rote memorization, and the study mode is good for learning more about the “why” of the q&a’s. Highly recommended! ### 5/5 — Extremely well designed and useful app! *2022-01-24* Using the Sheffield app for ADX prep takes so much of the stress of study away with its intuitive user interface and quantity of valuable content. The app is updated regularly so you know you’ll be learning the most up-to-date FAA questions. Has made the world of difference in comparison to going through various lengthy pdf’s. Definitely worth the cost! ### 5/5 — Excellent Prep Tool *2022-01-20, version 2.1* Used the app to prep for my ADX test that I took on 01/19/21 and passed. The app prepared me for all the types of questions that were given on the test. The different modes of study, quiz, and test make it perfect for each phase that you are in when preparing. ### 5/5 — Very Helpful *2021-07-29, version 2.1* This app was so helpful in studying and mastering every subject for the ADX written. It was nice to be able to take a test/quiz on my phone at any time. If you do a little bit each day, you eventually have all the subjects down. Thanks for the wonderful app! ### 5/5 — Great Studying tool *2021-07-27* This has been very helpful for studying for the ADX test. I like how everything broken down to all different sections and aspects. It definitely helps with retention and being able to increase or decrease the amount of sections to study and memorize. ## Most critical reviews (10 lowest-rated) ### 1/5 — Broken parts *2024-12-07, version 2.1* When I am opening up images on quiz or study mode using my I phone the arrow to go back disappears. Essentially, I cannot look at any charts or graphs provided. Totally broken. ### 1/5 — Would not purchase again if I had the option *2019-12-27, version 2.1* Exam simulator does not work on cell phone. This is not stated before purchasing. This was the main reason why I purchased it. Contacted Sheffield and nothing could be done. Requested a refund and none was given. This was not helpful at all. Would NOT recommend. If purchasing an app that does not work on cell phone go with Shepard Air. ### 3/5 — Good app until bug crash *2017-08-02, version 2.1* This was a good app until a bug crashed their system on the day of my exam making it inaccessible. I recommend the app for content and ease of use but you'd better have a backup plan in case it crashes. ### 4/5 — App UX issues *2024-12-21, version 2.1* No back button when having to view an image or diagram. So I have to exit the test and start over. ### 4/5 — Sheffield Aero FAA ADX app *2018-07-18, version 2.1* This app was very helpful in preparation for the ADX test. The app is well arranged, easy to use, and extremely fast. The study mode and quiz modes I thought were the best to gain knowledge of the material. The Exam simulator can be adjusted to you liking, but is still very similar to the actual test. ### 4/5 — Good app *2017-06-08, version 2.1* Great to have mobile version to study questions. ### 5/5 — Must have *2025-04-09* I bought this because I have a lot of downtime at work. I was able to use this instead of scrolling Instagram for hours on end. It is definitely worth the price. I ended up passing the ADX exam with an 89, so I was glad I had this to use. ### 5/5 — I passed!!!! *2025-01-27, version 2.2* I used this app to succesfully pass my ADX. I have zero aviation experience and I was able to get all of the information I needed to pass my exam. 100% recommend! ### 5/5 — Thank you Sheffield! *2024-09-14* Thanks to this app, I passed the ADX with ease. The study mode really helps you memorize answers in a flash card style format. The simulated exam mode helped me see what the real exam would be like and it allowed me to see if I’m trending up in my score. Hint: I’d recommend you average between 85-90% on the simulated exam before taking the real one, to practically guarantee a passing score. Thanks again Sheffield for helping me get this useless, but extremely important exam out of the way so I can focus on actually studying to become a dispatcher! ### 5/5 — User friendly *2024-08-20* I appreciate how user friendly this app is! There’s various ways to study in test mode, quiz mode and study mode. If you want to know the “why” study mode is for you. I prefer quiz mode. One of the strategies I used was to take the exam simulator 10+ times and score 80%+ consecutively. The exam log saves your exams so you can review them and learn from them. Great app! ## Most praised reviews (6 highest-rated) ### 5/5 — Great ADX Study Tool *2024-04-01* Love the ease of being able to have it on multiple devices! I use it most on my phone and enjoy being able to study while on the go and at the gym. Thank you Sheffield for creating an ADX study product that we can trust!! ### 5/5 — Fantastic Test Prep App *2024-03-29* This app is amazing! It helped me pass the ADX test. A lot of the questions I studied from the app were on the actual exam. The interface is easy to use, and there are tons of practice questions covering everything I needed to know. I especially loved the study mode feature because it helped me to track my progress and focus on my weak spots. The explanations were great and I appreciated whenever the explanations included statements about what we would realistically come across as a aircraft dispatcher. I would start off with study mode then I would do quizzes on each topic from study mode then move on to test mode. Highly recommend for anyone looking to take the ADX! ### 5/5 — Very convenient app for someone starting out with aircraft dispatcher. *2024-03-17* As someone who didn't have have prior aviation experience coming in, Sheffield's study app is very convenient for someone is just getting started with their dispatching career. Initially after downloading the app, you a prompt a login screen(obviously). At first, I thought I need to have a account by registering their course, but signing up is pretty simple. It is only after you login, and want to access additional study material where you would have reach out to Morris access to additional ADX study material. Just let him know you purchased the study app, and he will grant you access to the materials. While you are studying, the app gives detailed explanation to the answer, and even you initially get an answer wrong, it can guide you to the right one. There were some some concepts that were a bit confusing and so I had to do some internet research to better understand unfamiliar concepts in aviation including any abbreviations that the exam throws at you. I look forward to a dispatching course with Sheffield in the future. ### 5/5 — Great resource!! Main reason I passed the ADX *2023-10-30, version 2.1* This app was a phenomenal resource for studying for the ADX exam. It really helped me prepare, quiz myself, and then practice for the exam itself. I highly recommend this app for anyone that is studying for the ADX. I even was able to take practice quizzes while at the beach with my wife. (I know, what a great way to spend time “relaxing”). Definitely a main reason I passed the ADX exam on the first try. -Pat ### 5/5 — Excellent Study Aid *2023-09-25* I used the Sheffield ADX app to prepare for and pass the FAA ADX on first attempt! The app is well designed and comprehensive. It gives you the option to go deep into the learning and analysis behind each question in the test bank. I found it to be invaluable in my study. Highly recommended. ### 5/5 — Everything you need for ADX *2023-08-04, version 2.1* Great app, everything you need in one place to pass the ADX. I used the quiz mode mostly to memorize the question answers, and the study mode for instructions on graphing and book problems. Passed on first attempt! --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/). User reviews are verbatim App Store reviews.
