Scientist Club: STEM Quiz

Light up one star a day: ask "why?", guess, then see the answer. Fully in English & Korean. Stars connect into constellations as you think. Free to start — no login.

Science Club isn't about memorizing science — it's about asking "why?", making your own guess, and reasoning your way to the answer. A daily science-thinking app for anyone curious about science (ages 9 and up).

Each day you light up one star — one science idea. Before you see the answer, you write your own guess. Then you check the answer and a clear 3-line explanation. The goal isn't being right; it's growing the habit of thinking for yourself.

[Who it's for] · Anyone who loves science or wants to dig deeper · Students, gifted learners, and homeschoolers building reasoning skills · Anyone bored by drill-and-memorize workbooks · Anyone who likes a quick daily "why?" — on the commute or before bed

[How you learn]

1. Guess — write your own idea before seeing the answer.
2. Check — a clear answer plus a 3-line explanation.
3. Connect — link each new star to an earlier idea so knowledge ties together.
4. Log — note today's thinking in your journal and watch it grow.

[A universe that grows as you think] Lit stars connect into constellations across four fields — Physics, Chemistry, Biology, and Earth Science. Clear every star in a chapter to complete it; clear a whole field to conquer it. Learning stacks up as a visible universe, not a score.

[Alone, and together] Post short research notes about what you've learned and react to other learners' ideas in the Society space. Some questions don't have one right answer — think them through together.

[Light, but deep] Science Club rewards questions over answers and depth over speed. It's built to help you grow the habit of asking on your own. There are no ads, and you can learn two new stars free every day. Want more? An unlimited pass is available (a one-time purchase, not a subscription).

[English and Korean — both] The whole app works in both English and Korean. Flip the toggle at the top-right of the home screen to switch languages anytime — meet the same science idea in either language.

Works on iPhone and iPad, with a landscape-optimized layout on iPad for a wider view of your universe.

One star a day, a universe where thinking grows. Start now — no login required.
