1★Recurring issue of not being able to access any courses except the EPA 608 Universal. They contacted me last time (a week ago) to let me know it was a temporary issue that they quickly resolved (and it was, within 24 hours) but it's doing the same thing again. I like this app because I can learn whenever works for me, but lately I don't have that. I'll gladly give the app 5 stars again after they address the reliability issues. If they don't, I'll have to consider ending my subscription.

4★it's a decent app with several courses available for folks wanting to get into a trade. courses are pretty straightforward and easy. there were several errors and questions in section quizzes that weren't at all covered, but I passed the 608 universal in less than 24 hours. the online proctoring is a huge plus and why I chose it. however, it's pretty slow to load and drains the battery quickly compared to any of my other apps.

3★Good content and quality. But I mark right choices and they be wrong. You can pick the right answers and it would still say you missed one etc. Lagging after you complete a modules/ quiz. But you can't beat the free. I would of been done on my type one. My type one I had to redo it . Cause the app kept saying not answers then jumps around. But good information..

4★SkillCat has some good training on the app. Some of the more basic stuff is REALLY basic, but maybe some people need it. Working on my EPA Universal, finished my EPA Type 1. If I have a complaint, it's that after finishing a quiz, it doesn't automatically show your score...you must go back to the list of modules, click back onto the quiz before you can see your score. This app is good...and best of all, it is COMPLETELY FREE. Great resource for a new HVAC worker or one wanting to learn HVAC.

4★Overall, great app for EPA 608 Universal Certificate. Nothing beats free. Just a few issues with the app. Some questions on the quizzes get marked wrong when they are correct. Some questions are ambiguous. During the actual exam, I had several questions appear multiple times. Also, occasionally while navigating through the course, it would take quite a while for the menu to appear.
