Why I built it
The story behind DayQuizz.
I wanted a small daily habit that leaves me a little sharper — something you finish with your morning coffee, not another app that eats your evening. Ten questions felt right: quick enough to never skip, long enough to actually learn something.
So I built DayQuizz. Every day there are ten fresh questions in each subject — English, Spanish, Math, History, Science and Trivia. Get at least one right to keep your streak alive, and watch your flame grow.
The scoring has a bit of bite: easy questions cost more when you miss them, HARD mode doubles your points, and if you go negative your flame freezes over. It’s a game, but you’ll come away knowing something you didn’t yesterday.

FAQ
Questions, answered.
Is DayQuizz free?
Yes. Pick one subject a day for free — ten questions, both modes, streaks and the leaderboard. SERIOUS is $5 a month for every subject, every day, and you can cancel anytime.
How does scoring work?
In Easy mode a right answer earns +1, +2 or +3 depending on difficulty, and a wrong one costs −3, −2 or −1 — easier questions cost more. HARD mode doubles your points, up to +6.
What keeps my streak going?
Answer at least one question correctly each day. Miss a day and it resets to zero — that’s why SERIOUS members get a daily email reminder if they haven’t played yet.
Do I need an account?
No. You can play as a guest right away. Register for free to save your points, streak and stats across devices.
Can you build a tool like this for my business?
Yes — that’s what I do. Besides my own apps, I build websites and custom web tools for clients, from games and learning apps like this to tools that run your business. Tell me your idea and I’ll tell you how I’d build it.
