What you get, every day.
Fresh questions daily
A new set of questions every day. You'll never open the app and wonder what to study — the quiz sets the agenda.
Patterns and SOLID coverage
All 23 GoF patterns and every SOLID principle are in rotation. Questions span identification, application, and trade-off reasoning.
Instant explanations
After submission, each question reveals a concise explanation — not just the right answer, but why the others are wrong.
Streak tracking
Your streak is your scoreboard. Miss a day and it resets. This mild pressure is what makes the habit stick.
No setup needed
Open, answer, done. No configuration, no category selection, no timer to set. The quiz is ready when you are.
Topic accuracy tracking
Over time, you'll see which patterns you consistently nail and which ones keep tripping you up. Focus your study accordingly.
Show up every day. That's the whole system.
Consistency compounds faster than intensity. Ten minutes of daily recall practice outperforms a four-hour weekend cram — and a streak makes consistency visible.
"Miss a day, the streak resets. That's the point."
The reset is not a punishment — it's the mechanic. Knowing the streak breaks keeps you honest. Most users report the streak itself becoming the motivation after the first week.
Who it's for.
The Daily Quiz is designed for engineers who want to maintain and sharpen their LLD knowledge through consistent, low-friction practice.
- Engineers in active interview prep who want daily micro-practice between full sessions.
- Senior engineers keeping design pattern knowledge fresh without heavy time investment.
- Students who've read the patterns but need retrieval practice to make them stick.
- Anyone who learns better through testing than through passive reading.
