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.

Hi there — really sorry again for the inconvenience earlier. We wanted to let you know the issue was resolved within a few hours that same day. We totally understand how important a smooth, reliable experience is — especially when you're trying to learn on your own schedule. Thanks for your patience, and we truly appreciate you sticking with us.

really great app, I highly recommend it. giving it 4 stars instead of 5 only for 2 reasons. some training modules are buggy, and it's really expensive to buy a physical copy of your certificate card when you earn a certification. what I liked about it is that there are so many courses and certifications you can do at any time any place easily on your phone and learn so much about multiple trades.

This app provides online training for MEP trades. You have to pay a subscription fee to access courses. Unfortunately, some courses, though listed on Skillcat, aren't included in the subscription. The same is true for some final exams of courses. You can take the course on Skillcat, but you have to pay extra to take the final exam and get the certificate of completion.

Thanks for the feedback — we understand how this could be confusing. SkillCat includes 300+ hours of training and many certifications within the subscription. Some industry certifications like NATE, OSHA, and CPO do require separate fees wherever they’re offered, while many other courses and certificates are fully included.
