  • Has had a critical flaw for years... Sep 12, 2019

    By scmgames2
    For at least 3 years (the time I’ve used it for) I need to be on WiFi or it won’t be able to load the questions. I have an iPhone 7 Plus. I have no other apps with this problem. Also the UI hasn’t been updated in years... really unfortunate. Incredibly useful when it works.
  • Worked great at first Feb 19, 2019

    By Lolokaynickname
    The most recent update broke this app - at least for me. I now have to tap through five or six error notifications (which always redirect me to the start page) to even begin a lesson. Sometimes I have to restart the app multiple times to get a question set started. The display for the questions has been “zoomed in” for some reason (seriously, just why) and the answer bubbles are now less responsive to tapping (you have to tap the answer more firmly). Loading times are also longer. These issues occurred only with version 3.0.1. This app used to be so helpful. Now it’s barely functional. I hope these errors get addressed soon.
  • Fair app but ..... Sep 1, 2018

    This app it not apple iOS friendly in regards to interface. The display is blown out. What you see in the app previews is most likely a windows/android based phone. My iPad and iPhone do not display question and answer choices all on one screen. You must stroll to see lower answer choices. This is annoying considering how many questions you are tackling on CertMaster. You indication of a incorrect or correct answer overlaps answer choices and is sometimes hard to distinguish. Again after the 50 questions this optically exhausting. Hopefully this can easily be addressed.

    I started using this app to study for my Security+ and in the beginning it was great. I was able to go between my phone and computer to complete sections and they stayed synced. But now, I can't even get into a module without the app crashing and at the worst time for me,(seeing as how my test is in a few weeks). I really wish they would fix this bug. This app was convenient for me due to my job, but now, it's hindering my studies.

    While it doesn’t look like the UI has been updated for the iPhone X, it doesn’t take away the usefulness of the application itself. It’s very convenient to have considering I’m not always able to sit at my computer to review and or study. If you’re always on the go but still want a tool to review before these exams this app is WONDERFUL to have. Do not forget about it!

    This app crashes very often. When it does work it's a really nice experience, but when it crashes there is nothing you can do except wait a day and try again.
  • A bit sloppy so far Nov 25, 2017

    By the-exception
    Try signing in. The sign-in button does nothing after pasting a password. Tap the pwd field again then tap return. If you don’t figure this out and think your login isn’t working or something then tap the Just getting Started? Link below. Now if the option here is to login because you are already registered, then it takes you to the web! There is no function to return you to the app’s home screen! So you have to close the app. Lol great job.

    Good app. Good practice. Need to NOT charge $200 for certification. If I'm paying $200 and I apply for job. What the point of interviews. I paid and pass certification. What more do the company need to know other than who I am. Need to create more on hand jobs or on the job training than having to be certified. Ridiculous!

    I'm studying for a certification exam and I'm not very advanced but this interface is easy to do in between shifts at work, at lunch, before class and during any other down time. Exactly what I need for my tight schedule. Hopefully these questions prepare me for the exam!

    I am so grateful there is a user friendly app for CertMaster. It made it more likely to use and more accessible to use. RECOMMENDATIONS: Please add the smart refresh option to the app. The mobile version implies the user is on the go and wants to make progress.

  • Outdated UI. Login Issues. Unusable iPhone XS Jan 6, 2021

    By methodchild
    Ok so I rarely write reviews, but this app. I mean come on. It looks like this app only gets updated once a year. Even then the notes show it’s barely on life support. This app needs a modern overhaul. For me it’s unusually. I am unable to use my cert master credentials to login. I’ve typed it a dozen times no effect. Type it in a browser and first try I get in. Try to copy it from a note and it won’t even let me hit the login button (probably a problem with clipboard copy/paste). Also with respect to the UI, given I don’t make it far, It looks like this was designed for an iPhone 4. The resolution is low and looks like it was expanded to fill a screen the size of a 6 at some point. Now a days were all using 1080p or 2k OLED screens. It just looks ancient like 720p ancient. I don’t know if I’d want to use it at that resolution even if I could login. Please update this app!

  • Sep 21, 2020

    By Jarod Tresner
    This app is 6 years old and looks like it was made and is maintained by one person (basic stock photos/very simple effortless design). If you leave for anything at all and then go back into it, it will crash every time no matter what. Its nice to be able to practice questions on my phone but you would think they would put in a little effort for all the money paid to access anything on there.
  • Mar 11, 2021

    By Jay Findley
    It's not even usable. You would think for as much as you pay for certifications and the study material they would make an app that works. It would be useful for practice before my exam, as I travel a lot.

    By Steven Fteven
    Awesome app but crashes alot. Only way to get it working again is to uninstall/reinstall in order to work again.
  • Useless without additional purchase Aug 16, 2018

    By Joey gggdyyhvx
    I hadn’t looked into the website before stumbling across this app while practicing for my A+. They need to do a better job to imply you have to actually purchase the full courses (couple hundred dollars). Thought it was a free useful tool to help practice, disappointed. Please more clearly express that without larger purchases this app is useless. Once I maybe purchase a course one day I’ll come back and edit this
  • Feb 11, 2020

    By Kendra Plant
    It would be great if these A+ questions were proofread and if the app didn't constantly crash. I hope to see an improvement as this tool is being used in my certification class! I wish there was a a spot to send feedback on the screen for each question that is written poorly so it could be reviewed.
  • Just a mess... Feb 24, 2020

    By GalaxyA1
    Between the incredibly unintuitive UI and the abhorrant load times for questions, it’s outright shameful for training software that you pay HUNDREDS OF DOLLARS FOR AT MINIMUM. Each certmaster course is somewhere in the 150$ range so that’s what you’re actually paying for, this app is NOT FREE. It’s also unacceptable that the iPad version of this app is just a port of the phone version, making NO use of the additional screen space. Put funds into a better user experience rather than the pockets of the suits at the top!!

    If you enrol on this courseware, be sure to do it in a browser or desktop. When using the app, progress outside the app is not synced. Periodically crashes too and laggy. With regards to courseware, reinforcement learning algorithm is generally suitable as exam practice, though some questions are suspect, and explanations provided for some solutions are too generic (boilerplate definitions) or not contextualised to question (unable to explain why an option is correct/incorrect).

  • Passed A+ & Net+ Jul 12, 2017

    By joey.jacks
    Using this app has helped me pass the A+ and Net+. Studying for Security + now. App is a great help for studying during busy times. I have a Full time entry level IT job and 3 kids at home. Did not study IT in college and this app plus the Sybex books have helped me understand the fundamentals of ITS.

    Amazing, I'm not a fan of the price tags of the CompTIA CertMaster packages but these questions are very well put and straight forward. I've taken the 220-901 and studying with these questions helped me to pass my test. These questions do a good job of breaking down the sections and subsections of the exams.
  • Works very well Sep 27, 2018

    By Tech224
    Works as well as accessing the portal via a computer and remembers where you left off in the chapters. Occasionally, the app will ask you to sign in again. Overall, this app works great for practice tests and studying!

    By Robert Ronayne
    Using Linux + which is new to me so it's overwhelming. I also took an introduction to Linux class. This forces you to retake questions you get wrong. Repetition until you get it. I love the layout. I think it's a year paid subscription vs 3 months for some
  • Excellent Product Nov 21, 2018

    By ColumbusGaNerd
    I'm just happy Comptia offers an app! Other 'popular ' Comptia study products do not offer that option. And many users are thus stuck with the desktop option of studying only.
  • Sep 27, 2018

    By Lonni Noris
    Awesome study guide, passed both A+ 901 &902. Occasional crashes. And occasionally a question wouldn't load but the answers would. If left on more than 10-20 min without using then would have to close out and restart
  • Good Companion for when website is down May 11, 2017

    By arsherwood23
    Works great as a partner with test prep courses. And since it's from CompTIA you learn how they ask questions when it comes to the actual test.

    By Michael Baxter
    It is a good study tool. I dropped a star off the review because it asks you to rate and review it multiple times in a study session. That gets annoying and distracting and breaks your study flow.
  • My Experience Sep 4, 2018

    By KPatton80
    I do like the app but wish that the modules could be downloaded and accessible offline so it uses data when traveling. Also the questions need to change with algorithms.
  • Aug 26, 2019

    By Ivan Polyak
    Not sure how the app is relevant for the exam, but seems fairly good. I however miss a feature that would allow to test knowledge accross all modules. For now one can only learn/test within one chapter/module at a time.

    By RandomName6863
    The app would be great if it weren’t so buggy and glitchy. Every time I open a lesson after closing the app it runs through the same beginner notices (how to chose an answer, etc.); there are multiple errors and error messages per session, and you sometimes have to kill/ restart the app multiple times to get it to work correctly.

  • Please fix this app Jan 5, 2021

    By Kendrastic
    I have used this app for both A+ and Network+ certification practice. There are frustrating typos in both study materials that I don’t understand why they wouldn’t proof read and fix. Also, the constant scrolling at the top of the app while you try to read the questions is very distracting. If these issues were fixed I would recommend the app for preparing for the exams.
  • Not great... Dec 2, 2017

    By TooManyApps
    The app clearly not a priority to CompTIA at all. It’s very dated, not what I expected from the CertMaster curriculum. The app is low res, never keeps you signed in, and doesn’t display the same progress metrics that you’d see when using the website. (Last updated 7mo from time of review) The curriculum itself is good, just not the app. I hope CompTIA releases an app development certification so their devs can take it.

    Great app when you get past the 40 million times it crashes trying to sync it with your account, that is, if it ever does sync with your account. Paid $200 for security+, you would think there would be a functioning app.
  • Feb 28, 2019

    By A Google user
    IF there's an upside to this awful app, it's that it's just as awkward, misleading, frustrating, and poorly executed as Comptia's actual exams, of which I've now taken three. Do yourself a favor and just avoid the brain-numbing ineptitude of Certmaster altogether.
  • I guess it "works" Dec 7, 2020

    By Cormin
    It's not taking advantage of phone screens from the last 3 years. Not a good look for being a cert that has an entire section on mobile devices. The list doesn't show progress you've made in that section until you click on it. It's just very lazy. Unfortunately the web experience is better. Even their own app store screenshots are taken on a device that shows it's not optimized for newer devices. You can see the black bars in their own screenshots. That's so bad! Tapping an answer takes just long enough to register that I hit it twice and it reacts twice. It shows the tips every time I leave and come back to the app.
