3/5Good study questions, poorly optimized app
While the study questions are good, the app itself could use some help. It is not optimized to work with newer iPhones with the “dynamic island”… the back buttons barely work and need to tapped multiple times in different areas for it to be registered as a click. Some of the text is also hidden behind the “dynamic island” making it unreadable.

5/5Great Practice Tests and study options!
This app is definitely what got me through the test to get my AC certification. Spent 6 total hours going through the universal and type 1 questions and aced those two sections when it came test time! Would definitely like it updated to follow more in line with actual wording and add some questions that weren’t on the modern test. Well worth the $10. Please keep updating this developers!

5/5Perfect test prep
Anyone looking for an edge on taking any level of the epa 608 needs this. I wasted money on the book, on study plans and my adhd just can’t lol. This honestly made the test a breeze, I aced it first time, thanks to this app. It’s simple which makes it perfect, easy to follow and if you get distracted easily like I do this is the app for you. The minimalistic look is what kept me from getting distracted. Use the study part to become familiarized with the questions on each section. And then use the practice tests as a way to hammer in the answers. Before you take your test, do a final practice test on each section individually. Doing that helped me, hope it helps someone else with a similar squirrel brain.

3/5Almost Perfect
I should start off the review by saying that the app is good in respects to what you can expect to see on the actual exam and should be used more as a supplement to actual studying (which I recommend skillcat), but I did note a few things that felt careless by the developers. For starters, I saw it had older and outdated questions that aren’t in modern versions of the section 608 exam. I’m not sure how the questions are gathered but they should be up to date with modern versions and exclude content from outdated versions of the exam this app is for. This aspect really fluffs the use of this app and provides unnecessary information and questions that gets in the way of studying for a modern version of the section 608 exams. Another thing I took note of was the app experience falling short in optimization, I was surprised to see there wasn’t an option to go back to previous questions on the practice tests. All in all, I did find this app useful to test my knowledge in preparation for the section 608 exams but felt held back by all the outdated content.

5/5As good as it gets
Obviously any app is gonna have its issues. Yes a couple of the thousand questions are outdated but it still gives you all the information you would need previous to taking the epa 608 exam. The app has multiple different options and levels for review and helps you out when there’s certain questions you have a lot of trouble with.
