5/5Really great for Junior Engineers and CS majors
The app is really good if you’re trying to learn system designs way ahead of entering the job market, or if you’re already a junior engineer trying to level up. I’m currently trying to switch careers into engineering and it’s been helping me learn as much as possible about system designs.

4/5Great with one issue
overall really great and helpful app. My one complaint is that the titles of the questions generally answer the question. You match the title with the option that has that phrase or name in it and it’s correct ~80% of the time.

1/5Just the average grift
You can literally build the same exact thing yourself, using AI and ironically enough learn the concepts better than a bunch of multiple choice questions that you have to pay 8$ a month for, dont waste your time or money on this

5/5Dark mode please
Amazing material, could use a dark mode though

2/5Stuck in the setting menu - bug or intentional?
I was really excited to download the app after seeing it on social media, and the intro quiz experience was well done. After completing it, I was immediately overwhelmed with upselling menus and now I am locked at the “Settings” menu until I pay. Is this a bug or is this intentional? It’s not clear either way, it’s a disappointing experience for someone who just downloaded the app 30s earlier.

An hourglass appears in the last five hours of the day if your streak is at risk • Combo multiplier: chain correct answers for up to 1.5x XP Practice more, your way: • Quiz sessions: 5 random questions for a flat +25 XP • Endless practice: scroll through questions whenever you want more reps • Spaced-repetition review queue: questions you miss come back on a 3, 10, then 20 day schedule so the tricky ones actually stick Learn the fundamentals: • 14 lessons covering system design basics, from load balancers to CDNs, with native diagrams and a quick knowledge-check quiz at the end. Get all three right on your first try for a perfect bonus. Smarter question UI: • Ordering questions: tap an item then tap where it should go, with positions numbered live.
