Way too expensive for what it is
Heavily vibe coded slop
Not good
Looks decent but doesn’t work (like at all) without a $10 a month subscription
Paywall to learn?
£60 a year or £8 a month for something you could learn online. If it was free with ads/ one time purchase I would have considered given that the app doesn’t look too bad. A shame that profits come before educating in this world
Paid
Don’t say subscribe for full access when you can’t do anything without a subscription, its subscribe for access at all.
Good try on the upsell
Downloaded after I saw an ad on insta but was very disappointed to see that this “Duolingo for devs” is just a cash grab with no free tier, just a subscription bar the moment you download the app.
Disappointing
I was really excited to find a quality resource like this to study system design, especially one that described itself as Duolingo-like for the novelty factor, but this wasn’t that. You are immediately forced to pay for 100% of the content sight unseen and are locked in a settings panel, that ironically says “Subscribe for full access” when you have NO access. The apps likeness that you are using to market this all have free tiers and I would have been very willing to pay for premium features if it improved the base app experience and I knew that the course material is high quality.

Subscription is crazy expensive
£60 a year?! Should be one time unlock or free with ads
Slop
I’m going to be honest, I was very excited for this, but this app is very, very obviously just AI slop. I’m not saying using AI to make the app is bad, I am NOT part of the “AI bad” crowd at all, but you can kinda tell that this app was just entirely scaffolded and made using AI with little human effort. The UI/UX is weird to say the least, the quizzes and lessons just feel like I asked ChatGPT/Claude to “give me system design questions”. I don’t know how to describe it, but it’s soulless and it doesn’t feel like it was engineered by someone with an actual curriculum in mind. I love the person behind this’s videos so I’m disappointed

Bait and Switch
Trash, gets you going with questions and then sends you into an eternal loop begging for money. It’s 100% paid. They need to be forward with that from the start, not letting you create an account and then the eternal loop.
It’s great!
The spaced repetition feature is the best.
Stuck inside Settings
Whenever I log-in I get redirected to the settings page with literally no way out. I can’t use this app…
Not Really Like Duolingo…..
It claims to be like Duolingo, but there’s basically no free access. You either have to pay or you get stuck on a weird settings page with no clear way to continue. Very disappointing.
App is completely paywalled👎
You can’t even leave the settings menu without buying a subscription
Stuck, app not working
I answered some of the questions, but now it looks like I’m just stuck in a Settings menu. I can’t get out of it. This app is very confusing.
Zero features behind a paywall
Clickbait TikTok content creator so called ex FAANG after internship trying to monetize. Nice try
I love it so far
Love it
Misleading Marketing
I appreciate what the Devs are trying to accomplish but lead with using the app requires purchasing a subscription.
Nonexistent Free Tier
There isn’t an available free tier. Everything is hidden behind a subscription that was not advertised as a part of the developer/creator’s various videos. The introductory quiz was well made and had a lot of potential.
Stuck on settings
Absolute garbage for trapping a person on settings page till one subscribes. This kind of Holding hostage behavior is cheap and trashy. At least do a freemium tier to let people get used to the app then let em decide if they want to pay or not.
Stuck in Settings?
I downloaded the app, completed the intro quiz, and then got stuck on the setting page somehow. Someone needs to devmaxx their UX skills…
