Start where you are
A placement check of about 10 minutes, with a “Not sure” button, so lessons begin at the right place instead of at hydrogen for everyone.
For high-school chemistry
Learn the whole periodic table, a few facts a day.
Short lessons teach each element with a memory hook and its place on the table. Practice brings every fact back right before you’d forget it, and the games use only the elements you’ve learned.
No sign-up needed to try it. Works on phones, Chromebooks and computers.

Play five of the games
Name an element and see its memory hook, find squares on a blank table, sort metals from nonmetals, match symbols to names, and spell words with element symbols. About three minutes, using the first 36 elements.
In the app, the games use only the elements you’ve learned, and the ones you miss come back sooner until all 118 stick.
How it works
Teach first, then practice, then play
Every element is taught before it’s tested, and every fact comes back at the right time.
2
Meet a few elements at a time
Each lesson gives an element a memory hook, shows its place on the table, and shows how to work out its number from the noble-gas landmarks.
3
Practice that sticks
Spaced practice brings each fact back right before you’d forget it. Tap Sure, Think so or Guess: a lucky guess doesn’t count as knowing it.
4
Play with what you know
Eight games, from Element Hunt to Mendeleev’s Puzzle, use only the elements you’ve met. Ranks, badges and streaks keep it going.
What’s inside
Built around the topics of a high-school chemistry course.
All 118 elements
34 lessons and more than 800 facts: symbols, names, numbers, groups and periods, families, mass, valence electrons and electron configurations.
Quizzes with grades
14 graded quizzes, with a percent and a letter. Retakes get new questions, and the best score counts.
Chemistry 1
17 lessons for a first chemistry class: trends, ions and bonds, naming compounds and acids, forces between molecules, equations, precipitates, and acids and bases.
The Lab
Spin 3D atoms, build an atom, mix two solutions to see what forms, balance equations, and get coached through naming any compound.
Works anywhere, even offline
Phones, tablets, Chromebooks and computers. Install it like an app; it keeps working without the internet.
One device, several learners
Brothers and sisters can share a tablet. Each person has their own progress and sign-in, with an optional PIN.
For families
See the week at a glance
- The Progress tab shows days practiced, facts mastered, the tricky ones, and one question to talk about together.
- With an account, parents can get the same summary by email on Sunday evenings. Weeks with no practice are skipped.
- A parent area behind a PIN: milestone rewards, quiz grades and resets.
- Trying it needs only a first name. No ads.
For teachers and schools
Your class, on every device
- Add students by email. Each one signs in with an emailed code, then can set a password.
- See each student’s progress, streak, minutes per day, quiz grades, and the facts where they need help.
- Teacher accounts see only their own students. Resets for a lesson, an element, a quiz or a whole account.
- Covers atomic structure, how the table is organized, periodic trends, ions and bonding.
