Please fix this. I’m a really slow reader and the audio function helped me rip through a bunch of questions. Now It takes me much longer to get through the same amount of test questions. ### 5/5 — Spot on *2025-05-19, version 7.6.2* Just went 5/5 on first engineers unlimited, in and out in 4 hours. Sea trials made it all possible! Questions were super up to date, maybe saw 10/350 I didn’t recognize ### 5/5 — Well worth *2025-05-14, version 7.5.8* Just passed my 1ae tests just using this app. You don't need any other study material ### 5/5 — The perfect study app for USCG licensing exams *2025-05-09* I initially used this app 4 years ago to study for my 3AE license exams, in unison with my license prep course. I stand by this app and the structure of the study material and ability to break down sections and generate test. It is the ONLY material I used to pass my license prep course as well as my exams. The app made it so easy to study and generate test, it became addicting to study! It actually motivated me to study because I actually enjoyed the interface and the ease of access of all the material. I also enjoyed how some test questions that required a diagram had a direct link to it making it easier to navigate and study. Whereas some other applications/study material require you to scroll through an entire pdf or web page before finding the diagram. The time it takes to find the diagram on other apps, I’ve already forgot the question and have to flip back and forth several times. I also enjoyed the ability to flip through sections (and subsections) with or without the answers shown AND to shuffle the order of the questions. I am back again to study for my 1st Unlimited! ### 5/5 — Worth the investment! *2025-05-02* I started my Chief Mate studying with Upgrade U and then Lapware, and added in sea trials at the end. Should have used sea trials from the beginning! I like the ease of the program both on the go and on a laptop, and the AI function to explain things is very helpful. Sea trials was a great addition to my study plan and would recommend to anyone to use for studying for Chief Mate! ### 5/5 — Very useful study tool *2025-04-28, version 7.5.4* This app has been the best resource I have used while studying for my original 1600 Ton Mate license. I suggest it to all mariners seeking to advance from AB to Mate ### 5/5 — Organization and tools! *2025-04-21, version 7.5.2* I have been studying for my 2nd/3rd mate unlimited and it is by far the most organized/structured tool I have used yet! ### 5/5 — Helps in a big way during a crazy time *2025-04-20, version 7.5.2* Everybody had that pit in their stomach going in to try and get their license, sea trials helped thoroughly prepare you for the exams and provide the solid knowledge base to confidently test and pass!! Eternally grateful. ### 5/5 — Worth it for a working woman! *2025-04-01* I tested for my USCG 100T Masters and the Sea Trials App made it possible. While working 2 other seasonal jobs, I was able to study on the go and to the point with this app. There’s so much material to cover for any USCG license, but this app cuts to the chase– the exam questions. Highly recommend for anyone studying while balancing other work! ### 5/5 — 👌 *2025-02-25, version 7.3.8* Easy access and reliable app. ### 5/5 — MacBook Masters! *2025-02-04, version 7.3.5* So great to have a Mac friendly, instant access exam prep! Thank you Alex! ### 5/5 — Mac Masters! *2025-02-04, version 7.3.5* Instant access for those of us who have Macbooks! The question banks and setup are amazing! ### 5/5 — Review *2025-01-28, version 7.3.2* Great app, very streamlined in order to help with exams. ### 5/5 — License Prep MUST HAVE! *2025-01-09* I’ve been taking classes for the last year to prepare for taking my 3rd mates license exams. Sea trials has been an incredible tool in helping me prep for my license exams. It’s so much more than questions and answers and that’s what makes this app worth the money! The features really make this app standout from all others! ### 5/5 — Great! *2024-12-17, version 7.2.3* Sea Trails is the best app out there to study for mates! It has the most up to date questions out there and they continue to update. It’s so nice to be able to study anywhere on my phone. Definitely worth the money. ### 5/5 — Studying for third mates exam *2024-12-13* This app has been a great help to me in studying for my coasties. My school provides lapwere to me but I prefer to use seatrials as having the mobile app is amazing for studying deck gen/nav/safety. Pros: 1. Allows you to keep track of the questions you have looked over in study mode. This is the only one of the competitions that I could find that do this 2. Unlimited test generation (with subscription) 3. It’s on your phone 4. Makes you feel guilty when you miss days because it tracks how many questions you do pre day Cons: 1. Expensive, with new subscription model you pay 30 dollars a month. I used to pay 10. 2. The basic 20 dollar a month version only lets you take FIVE practice tests a MONTH. this is the biggest con in my opinion. 3. The explanation that is provided for the questions is often wrong and I have a feeling it was AI generated. Overall I still give it 5 stars as it has been very helpful for me to study. But if your school provides you with another service maybe skip this one because of the price ## Most critical reviews (10 lowest-rated) ### 1/5 — App Broke *2026-06-13, version 8.6.9* I downloaded app. Couldnt get it loaded. It konks out when trying to upload a photo for the account. Wont allow an upload. Couldnt use the free trial or anything. ### 1/5 — App must have a bug for new users *2024-08-15, version 7.0.9* I can’t create an account aug 15 2024. ### 1/5 — Can't Create Account *2024-07-02, version 7.0.2* This app won't allow me to create an account. It continues to state that my password needs to be 8 to 15 characters, however, it's more than that. **update ** 2 July 2024 Nothing has changed. There’s apparently still too many bugs needed to be fixed. It keeps kicking me back to a section I’ve already completed, and it doesn’t have the school I’m attending. ### 1/5 — Does not work (2024) *2024-06-03, version 6.2.1* Took the test in 2024 and only recognized about 20% of the questions after studying for weeks ### 1/5 — Unable to create new account? *2023-10-17, version 6.1.0* After filling out username, email, license, and photo the create account does nothing. ### 3/5 — Super Buggy Recent Updates *2026-02-28, version 8.6.6* Switched to vibe coding the app? Numerous recent updates and frequent app crashes. ### 3/5 — Engineering electronics *2026-01-25, version 8.4.6* Using app for studding DDE the general and safety stability and fire test is spot on. The electrical isn’t spot on at all maybe only a few questions I got on my test. Other wise it’s a great tool ### 3/5 — It’s okay *2025-05-03, version 7.5.6* Question bank is decent. Not all the questions though. It’s great for on the go and offline study. My biggest complaint is the lack of solutions. When you’re working a problem out, don’t expect this app to have solutions drawn out like Lapware. Might have to use both. ### 3/5 — Good App *2021-09-13, version 5.1* Better than Upgrade U. I like it ### 3/5 — Eh *2021-08-21, version 5.1* Eh ## Most praised reviews (10 highest-rated) ### 5/5 — License prep? Look no further *2026-07-28* Currently holding my Chiefmate unlimited oceans, this app was vital to me upgrading. I grew up using upgrade U but there is no comparison. Hammer the general modules on here till you’re making 90’s, in conjunction with lapware later on towards the end before testing and you will do just fine. Remember to test on the practice exams from the USCG website. Those exams will be very similar to the questions you will see exam day. 🫡 ### 5/5 — Thank you!! *2026-07-13* App works much better after the recent fix to the last mega update. I’m studying for my CM/Master Unlimited and this is my go-to app for studying. I love how it tracks your problem areas so you know what needs to be improved. Thank you for taking the time to respond to my last feedback post and fix the issue. You guys are great!! ### 5/5 — Passed! (Mate Unlimited GL I) *2026-05-19, version 8.6.9* Just want to thanks to the developers! No way I would’ve passed my tests today without it! Can not recommend this app enough if you’re studying for your exams! ### 5/5 — A+++ *2026-03-15, version 8.6.9* Normally don’t leave reviews but this is better than ChatGPT ### 5/5 — C/E limited *2026-02-13, version 8.6.2* This is all you need to pass the 4 exams the app is great and is way more relevant information than other platforms. Cannot recommend them enough.full disclosure i tried the books and MA and was far superior in every aspect.I rarely leave reviews but this deserves it ### 5/5 — Good Customer Service *2026-01-29* I was having issues with the UI and the app crashing. I reached out to customer service and they helped me resolve all of these issues. They were quick to respond and clear in their explanation on how to fix the problems I was having. I highly recommend this app. Currently studying for my 500ton mate’s tests. ### 5/5 — Best USCG Studying App *2025-12-03* I have been using the app and the website for a long while now. The new updated version has been helping me study so much better. I highly recommend giving it a try to see for yourself. The customer service on their end has also been helpful and responsive. 10/10 highly recommend giving it a try. ### 5/5 — Highly recommended *2025-08-17, version 7.9.6* Great app, expanding my knowledge on coast guards exams, very helpful. Would rate 10/10 telling all the mariners about this app. ### 5/5 — Good job Duffy poo *2025-06-25, version 7.7.4* Mommy’s milk :0 ### 5/5 — Bug when signing up resolved *2025-06-19* The developer was very responsive when I let them know that I could not complete the signup process. There was an app update after that and I was able to get started. The content and format look very interesting, so I am looking forward to learn more. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
