About this app

Trade School? More like Trade Revolution.
College is $100K of debt. Traditional trade schools are stuck in 1997.
SkillCat? It’s $10/month. On your phone. And way more fun.

We’re the only app where you can earn your EPA 608, OSHA-10, and Trade School Diploma while sitting on the toilet — and STILL come out certified.

300,000+ tradespeople already joined. What’s your excuse?

What’s Inside:
- EPA 608 & 609 Certification
* Official, accredited, and fully mobile. Core. Type I, II, III. Universal. 98% pass rate.

Who It’s Built For:
* HVAC newbies & seasoned pros
* Electricians & plumbers who want that paper
* Maintenance techs leveling up

Why SkillCat Slaps:
* Train from your phone. Anywhere. Anytime.
* No tuition. Just $10/month. Seriously.
* Certs that employers actually respect
* Built by real tradespeople, not some crusty board of directors

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.

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.

These guys and gals nailed it! Been doing construction my whole life, I'd like to think a fast learner as well, and their structure is phenomenal! I once heard "You don't know your trade well enough to teach it if you can't put things in elementary terms". Blows penn-foster outta the lineup, for sure. If your hungry, this is the right one for you 👍.
