Every element opens instantly, even offline.
Elemora is a periodic table built for learning. All 118 elements and every detail live inside the app, so it works with no internet connection, and nothing is locked behind a subscription. Look an element up, see the patterns, then lock it in with quick quizzes.

The whole table in portrait
All 118 elements fit your phone screen, with group and period numbers. Pinch to zoom; taps land on the tile you see.
Every detail, one tap away
Atomic number, standard atomic weight, group, period, block, category, electron configuration, state, melting and boiling point, density, electronegativity and discovery year.
Electron shells and real uses
A shell diagram for each element and a short line on where you meet it in daily life, like lithium in phone batteries.
Family colors
Alkali metals, halogens, noble gases, lanthanides and more, each in its own color. Tap a family to highlight only those elements.
Trend heat maps
Turn the table into a heat map of electronegativity, atomic radius, melting point or atomic weight to see periodic trends at a glance.
Five quiz modes
Symbol to name, name to symbol, atomic number, element category, and find it on the table. Pick elements 1–20, 1–36, 1–54 or all 118.
Mistakes and mastery
Wrong answers go to a mistake list you can practice again. Get an element right three times in a row and it is marked as mastered.
A little every day
Element of the day on the home screen and in a widget, a daily goal with a streak, and an optional morning reminder.
FAQ
- Does it work without internet?
- Yes. All 118 elements and their data are built into the app, so the table, the details and the quizzes all work offline.
- Is any element information behind a paywall?
- No. Every element and every detail is available without a subscription. Elemora shows ads to keep the app running.
- Does it show group, period and whether an element is a metal, nonmetal or metalloid?
- Yes. The table shows group and period numbers, each element has a category color, and the detail screen lists group, period, block and category.
- How can I memorize the periodic table?
- Start with elements 1–20 in the quiz, review your mistake list, and move to 1–36 once most are mastered. The memory tips section has sentences for remembering the order.
- Can I quiz myself on more than symbols?
- Yes. Besides symbol and name, there are atomic number, element category and find-it-on-the-table modes.
- Is there a dark theme?
- Yes. Choose light or dark in Settings. Temperatures can be shown in °C, K or °F.
- Where does the data come from?
- Atomic weights follow IUPAC standard values and physical properties follow public NIST reference data. Classifications that textbooks disagree on are marked as the common classification.
- Do I need an account?
- No. Favorites, quiz results and your streak stay on your phone.
