1. 5/5Save THOUSANDS w/ SkillCat

   *Real Customer, not a PAID review* I recently started using the SkillCat app, and I am thoroughly impressed with its latest update. The app is now more user-friendly and intuitive, making navigation a breeze. This update has significantly enhanced the overall user experience. One of the standout features of SkillCat is its tailored approach to user needs. The app offers a wide range of trade-specific certifications, including HVAC with the EPA 608 certification, electrical, and plumbing certifications and more. This makes it an invaluable resource for anyone looking to advance their skills in these trades. What sets SkillCat apart is its affordability and convenience. There’s no need to spend a fortune on trade school when you can access high-quality, accredited training through SkillCat. The app offers a free trial, and after that, it’s only $10 a month. This is a fraction of the cost of traditional trade schools, making it accessible to a wider audience. Overall, SkillCat is a game-changer for anyone pursuing a career in the trades. Its user-centric design, comprehensive certification options, and cost-effectiveness make it a must-have app for both beginners and seasoned professionals.

2. 4/5Good for learning but app stops working after free trial

   The courses were decent enough, and the EPA certification was far faster than other sites. The problem is that unless you pay for the continuing service, you will be completely unable to access any of your certificates or diplomas you might have earned. The website says that downloading the app will allow you to access these certificates by logging in and viewing your profile. The app simply refuses to load past the loading screen that says “loading you profile”, however, preventing you from doing this. I have waited ridiculous amounts of time on the screen on multiple connections to test this, and even re-installed the app. To be clear, the programs were all decent enough that a few months subscription would have been worth it to me, if I needed more time to complete a course or two. I DID pay the $50 to get a physical EPA 608 card, so this is not saying that everything should be free. It can definitely be worth it. Having been in the trades for years, everything I experienced within the app while it was working shows me it is a worthwhile tool. Outside of a few videos not working, some errors in quizzes and tests where correct answers were marked incorrect, or very poorly worded, the whole experience was good. I am only saying that I would not expect to be able to access anything after your subscription ends, which could be a major issue.

3. 5/5Incredible team for making this!!

   Incredible free app to learn hvac!?? how could anyone pass on this. I appreciate the developers and whoever spent time into this project. Education should be free and this is really really exceptional for free service. Opportunities can easily be grown from going through their courses!, It’s not the most high end online school but it’s simple and not over complicated with how they educate. I just turned 18 and getting my Epa certification I hope will benefit me greatly. Use this app to get a job or just learn. Honestly I thought Hvac was going to be impossible for me to begin until I decided to get Skillcat. Thank you so much for the free service!! I wasn’t born into a gifted family so the top-tech $$$ schools are out of hand so I rely to free information, Skillcat is superb with this!. 5 stars so more can see this!!! p.s. Carful with how much $ you’ll be making after a few years of Hvac it’s dangerously good. Get motivated and start working harder!

4. 3/5Interrupted mid-lesson by an indefinite loading screen

   So far I am enjoying the app and the course material for the EPA 608 Universal course. However, I can’t keep track of how many times the app has forced me out of the course when I’m watching a video or answering questions to give me a loading screen that lasts indefinitely. I’ve tried to wait for it to go away but I’ve waited several minutes in one instance. Therefore, I have to manually close the app down and reopen the app. Luckily it saves my progress on the specific module, but it’s not optimal. I would recommend fixing this issue because I don’t know how many times it will happen again, and if you’re watching a video and this happens, you can’t skip ahead to where you left off because they don’t offer a slide bar. Legit, you have to sit and watch the video from the beginning and some of the videos are 10+ minutes!! Please fix. I will give 5 stars if you guys fix and it doesn’t happen again! Yes, I am a paying subscriber!!! Yes the app is awesome with lots of content! For me, it’s just this one issue that’s the real dividing line of being an amazing app! Thanks for reading.

5. 5/5If you are like me and can’t afford tech school tuition or have time, then here me out

   I’m so glad I stubbled Upon skillcat One day when searching for free education. This app is amazing at teaching you the basics of not only HVAC but they also do electrical and plumbing. This a TRULY FREE APP. I went to a votech school for four years for hvac but unfortunately what you learn is up to the instructor and the school district. School setting is not for everyone. I’m using skill cat to refresh my knowledge and earn an epa certification which is awesome and I couldn’t even get one in my votech hence why I needed to go to more hvac school after high school. This is simply awesome and the fact that it is free is truly amazing. If you are someone who wants to leave the basics to see if the trade is for you, then you need to use this app. Explore electrical and plumbing too because it never hurts to learn more about other trades. I highly RECOMMEND
