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.
* No test center. No excuses.

- Accredited Trade School Diplomas
* HVAC. Plumbing. Electrical. Appliance Repair.
* Self-paced. IACET-accredited. Built for people with real jobs and no time to waste.

- OSHA-10 Certification
* Get it. Need it. Required by just about every company that matters.

- NATE Certification Prep
* Want more money? Certify like a boss. NATE preps are inside the app.

- 200+ Courses. No Fluff. No Filler.
* From "How to not die on the job" to "Fix the unfixable."
* Airflow. Wiring. Refrigerants. Motors. Diagrams. All killer, no filler.

Who It’s Built For:
* HVAC newbies & seasoned pros
* Electricians & plumbers who want that paper
* Maintenance techs leveling up
* People who are done with dead-end jobs
* Anyone ready to say “screw it” and build a real career

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
* We’ll even email you memes. Maybe a photo of our CEO stress-eating drywall.

SkillCat is the trade school we wish we had.
It’s funny. It’s fast. It’s accredited. And it actually works.

Download it. Use it. Change your life.
Your future self will high-five you.

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.

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 👍.

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..
