Store ratings include star-only taps from in-app prompts, which skew high. The peak and recent figures come only from people who wrote a review, which skews low. Compare each against itself: the drop is the signal, and a big gap between the two usually means heavy rating prompting is masking unhappy users.

App kinda sucks

★ · v7.0.5 · Aug 17, 2026

Not so much SkillCat. Just the layout.

Need help

★ · v7.0.5 · Aug 12, 2026

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

It’s hard to unsubscribe from them.

★ · v7.0.5 · Jul 28, 2026

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.

so glitchy

★ · v7.0.5 · Jul 6, 2026

The app is terrible. Super slow and always times out with network error. The content is decent but the design is terrible.

Poor quality

★ · v7.0.4 · Jun 13, 2026

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.

Problem with videos

★ · v7.0.4 · Jun 12, 2026

Videos are having difficulty playing

Bug/Issue

★ · v7.0.2 · Mar 24, 2026

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.

It was great

★ · v7.0.2 · Mar 2, 2026

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.

This app is horrible.

★ · v7.0.2 · Feb 27, 2026

Only half of the courses load. It litteraly sits there and try’s to load indefinitely. This app sucks

Always crashes, terrible app

★ · v7.0 · Nov 10, 2025

Hire some qualified engineers to fix your app

Glitchy

★ · v6.5 · Aug 17, 2025

When I try and restart it keeps loading. I tried deleting and re-installing. Same problem. Says something about not connecting to the server. I think it’s a server issue. Very unhappy and frustrated.

App not good

★★ · v6.5 · Aug 8, 2025

If I go away for a second, it starts spinning and then sometimes takes to final exam. Then spins when I try to go back to keep learning. Then I have to shut off the phone to reboot it.

Have to be super careful not to let the screen lock

★ · v6.4.1 · Jul 9, 2025

If you’re not exceedingly diligent to make sure the screen doesn’t turn off and lock, it will mark the chapter completed and you have to go back in and find where you left off. Super annoying mechanic.

Buggy

★ · v6.3 · Jun 3, 2025

Bugs all the time. Currently cannot even see anything in the certifications tabs.

Disappointment

★ · v6.3 · May 5, 2025

I can understand the appeal of this app due to the price, but the shortcomings of the platform have to be discussed. The app is a buggy mess, requiring frequent restarts to function properly. Recent updates have done nothing to address performance concerns. This would be acceptable if the material was good, but it's not. I used SkillCat for EPA 608, the main draw of the platform. The language of the course DOES NOT match the language of the assessment. You'll spend 10 hours preparing for questions that are never asked and you'll be asked questions you've never heard. This is a quiet bit of fraud and a real failure to properly educate students. There is no practice exam and you'll only get 4 attempts. I'm beyond disappointed and I hope SkillCat fixes these issues. Unfortunately, I don't think this will happen because of the captive user base of non tech tradies. Such a shame!

Subscription not working

★ · v6.2 · Apr 6, 2025

I am subscribing for a monthly plan yet the membership thing keeps popping up after i subscribe like. I keep subscribing over n over again but can’t even open one course why.

Not able to log in

★ · v6.2 · Mar 20, 2025

Not able to log in. App takes me to a log in page and then tells me that it is not accessible through the app.

Application bugs

★★ · v6.0.3 · Jan 11, 2025

Customer support is really bad. I reported an issue and never received a response from them.

I can’t finish my profile set up because I can’t get past the verify your phone number page

★ · v6.0.3 · Dec 10, 2024

I can’t finish my profile set up

App doesn’t work

★ · v6.0.3 · Dec 6, 2024

I’ve been trying to verify my number for days and it won’t register

App Does Not Work

★ · v6.0.2 · Nov 14, 2024

The app doesn’t work correctly to the point that it literally will not function even enough to be able to successfully complete a profile let alone then even attempt to do anything else. From the very start it forces you to create an account/profile and then uses a pop up webpage screen to then complete your profile before it lets you do anything further and the app will NOT let you scroll at all and even when attempting to tap as far down as possible to hopefully move the page down that way it still doesn’t work enough to get far enough and complete enough information to successfully complete the account creation screen. Additionally every time you attempt to close the app and reopen and try again it automatically forces any log in attempt to be account creation attempts instead which results in multiple error loading attempts before finally saying you have to complete a profile to continue which then of course will not let you do

Keeps shutting down

★ · v6.0.1 · Nov 10, 2024

Please fix as soon as possible. I’m using a m3 iPad The app shuts down right after trying to login with my credentials

App keeps crashing

★ · v6.0.1 · Nov 2, 2024

Because of a faulty app the site keeps crashing on me, requiring me to delete the app and reinstall. This makes the app and programs useless because I can’t even access the material.

Force closing

★ · v6.0.1 · Oct 25, 2024

App constantly force closing around 10 secs after tapping the app. Using iPad Pro 11 2024.

The mute button is overlapping the pause button.

★ · v5.3.3 · Aug 7, 2024

The mute button is overlapping the pause button. Fix it! It's impossible to press pause.
