Both are frustrating ### 5/5 — No Complaints *2026-07-21, version 7.0.5* Great app, highly recommend. 👍🏾👍🏾 ### 3/5 — Resubscribes without permission *2026-07-21, version 7.0.5* I had to delete the app off phone. I canceled subscription a while back, but recently just opened app and it apparently renewed my subscription just by opening the app without any confirmation message. Was good for some stuff, but if you’re not using it make sure and remove it off your phone to prevent this problem from happening. ### 5/5 — Videos glitchy *2026-07-19, version 7.0.5* Love the courses but the video glitchy and sometimes I have to close out of the app to correct it. Not sure if the because I downloaded the latest iOS 26.5.2 ### 5/5 — Great app *2026-07-18, version 7.0.5* This is a great app for EPA exam. ### 5/5 — Recomendación *2026-07-15, version 7.0.5* Esta aplicación me ha echo interesarme más por aprender cada día más acerca de mi trabajo ### 3/5 — Great App But… *2026-07-13, version 7.0.5* Love the app so far but I’m noticing the app loses connection on every final exam I’ve taken so far. It’s slightly annoying to have to keep restarting the app every final exam I take. ### 5/5 — Very wonderful *2026-07-07, version 7.0.5* Really all you need is this app and few hands-on experience. Love the app ### 5/5 — Very effective *2026-07-03, version 7.0.5* Extremely efficient at covering and preparing for the tests. The content is broken down into small segments with quizzes which made retention easy ### 5/5 — Trade Schools Beware! *2026-07-02, version 7.0.5* A well and clean app for a multitude of training and necessary certifications. 10$/month or ~96$/year is a great deal for the amount of time saved finding and learning by just trying to search up youtube tutorials or google searches. ### 5/5 — GRATEFUL *2026-06-30, version 7.0.5* The learning EXP through skillCat is out of this world and so simple to learn the basics to become a long term experienced technician in all the trades that they offer certifications in! Mahalo SkillCat🤙 ### 5/5 — 100% love it *2026-06-29, version 7.0.5* Definitely download it ### 5/5 — Gold Education! *2026-06-26, version 7.0.5* I’m so happy and glad that I came across this site-by far the BEST online training site I’ve ever seen and I’m a Certified Energy Engineer for over 40 years. The cost is insane!!!! Only $10/month-unbelievable. I completed the 608 course and learned a lot! Believe me, try this out and you’ll be amazed just as I am. ### 5/5 — Brazing and Soldering *2026-06-20, version 7.0.4* I had an opportunity to take this course way back 20 years .I found it interesting refreshing course. ### 5/5 — No access *2026-06-20, version 7.0.4* The app took my money but will not grant access to the courses and videos. ### 5/5 — Its the real deal. *2026-06-16, version 7.0.4* I can't believe how much I've learned and earned. Mind you I put in work and time. I promise, you will be glad you found this app... Nope, not an app, a tool that if used correctly can literally change the game. ## Most critical reviews (10 lowest-rated) ### 1/5 — App kinda sucks *2026-08-17, version 7.0.5* Not so much SkillCat. Just the layout. ### 1/5 — Need help *2026-08-12, version 7.0.5* I’m paying for the app but I don’t have an account with them? I have and account and even payed for it but when I sign in it says user not not find but I’m still getting charged. Need help finding original account or transfer my payment to a new account ### 1/5 — It’s hard to unsubscribe from them. *2026-07-28, version 7.0.5* Initially, my employer set up the subscription for me; later, when the company stopped paying, I took over the payments myself. Eventually, I realized I didn't need the subscription and decided to cancel it. I was using the web-based desktop version but couldn't easily find the cancellation menu there, so I had to download the app and log in to my account. I started the cancellation process in the app, but it redirected me back to the web interface, where I had to have a link sent to my email to complete the cancellation. It’s outrageous; someone else might fail to navigate all this and simply end up stuck with the subscription forever. I have never encountered such a convoluted cancellation process anywhere else. ### 1/5 — so glitchy *2026-07-06, version 7.0.5* The app is terrible. Super slow and always times out with network error. The content is decent but the design is terrible. ### 1/5 — Poor quality *2026-06-13, version 7.0.4* App freezes on almost all videos at, at least one time stamp in it.. You end up missing half of the video because it gets stuck at specific time stamps over and over. Don’t waste your money. Once it freezes the only way to continue is to go to the next segment of that item. ### 1/5 — Problem with videos *2026-06-12, version 7.0.4* Videos are having difficulty playing ### 1/5 — Bug/Issue *2026-03-24, version 7.0.2* I am using this app to complete a EPA certificate however while I am reviewing the material I am constantly being shown a POP UP that requires me to “choose a plan” when I already have a membership. This wouldn’t be a problem if the pop up didn’t kick me out of whatever I was studying and forces me to start again and this is every 5 minutes so it’s largely impossible to get any meaningful progress is a short amount of time. ### 1/5 — Great when it works *2026-03-11, version 7.0.2* It’s great when it works but every time you go to take a test it says network connection lost auto save failed and fills the rest of your test questions in with whatever it decides to. ### 1/5 — It was great *2026-03-02, version 7.0.2* This app was great, but now just loads and reloads but the name of the courses never show up, is frustrating. This needs to be addressed and fixed please. ### 1/5 — This app is horrible. *2026-02-27, version 7.0.2* Only half of the courses load. It litteraly sits there and try’s to load indefinitely. This app sucks ## Most praised reviews (10 highest-rated) ### 5/5 — yes *2026-08-31, version 7.0.5* epa cert ### 5/5 — Great online learning *2026-08-29, version 7.0.5* The best online course I’ve ever taken ### 5/5 — Hvac learning *2026-08-25, version 7.0.5* This program was so detailed and organized. Easy to watch the modules and listen to anywhere. ### 5/5 — Hvac *2026-08-19, version 7.0.5* They helped me get my EPA certification without them. I probably would’ve never got it. There are also a lot of good information.I would definitely recommend them. ### 5/5 — Perfect for the development of any career HVAC-R professional *2026-08-14, version 7.0.5* Some courses may seem redundant and often times as professionals we learn the majority of our skill set on the job, which is an excellent method, however it cannot be understated the importance of having certification which can aid in proving competency. 5 stars is not nearly enough to surmise the excellence of this application and the courses therein. Kindest regards and eternal gratitude, Kamil ### 5/5 — Learning made easy *2026-08-11, version 7.0.5* It’s fun ### 5/5 — Building operations *2026-08-08, version 7.0.5* Best app ever to learn and use as credential ### 5/5 — Amazing app *2026-08-08, version 7.0.5* Thanks to SkillCat I have been able to obtain a job in the hvac field and I can continue my learning as I go farther into my career. The EPA 608 certification course is the best out there and they keep it affordable. ### 5/5 — An Outstanding Learning Platform for Anyone Entering the Skilled Trades *2026-07-31, version 7.0.5* SkillCat has been one of the best educational resources I've found for learning HVAC-R and expanding my knowledge of the skilled trades. As a student in an Energy Management and Controls Technology program, I've used many different training resources, and SkillCat has done an excellent job of presenting complex topics in a way that's easy to understand while still being technically accurate. What I appreciate most is that the lessons are well organized, engaging, and self-paced. The combination of videos, illustrations, quizzes, and hands-on explanations has helped reinforce concepts that I can apply both in the classroom and in real-world situations. The certifications are an added bonus and demonstrate a commitment to helping students and technicians continue developing their skills. I also appreciate that SkillCat continues to improve the platform and genuinely asks for student feedback. That says a lot about a company that is invested in creating a better learning experience. If I could suggest one future enhancement, it would be adding the ability to highlight lessons, bookmark important sections, and take digital notes directly within the app. I think this would make it even easier for students to review material and build a personalized reference guide throughout their training. Overall, I highly recommend SkillCat to anyone interested in HVAC-R or the skilled trades—whether you're just getting started or looking to expand your knowledge. It has become a valuable part of my education, and I look forward to continuing through the rest of the curriculum. ### 5/5 — Excelente *2026-07-23, version 7.0.5* Es super buena y muy fácil de usar, realmente muy intuitiva, da gusto aprender con esta app --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
