Features

A table worth exploring.

All 118 elements in one clear grid — and for each of them, what a student needs to learn.

The whole table

All 118 elements including the lanthanides and actinides. Pinch to zoom and drag to move around.

Colour modes

Colour the elements by group, state of matter, block or school curriculum. Tap a legend item to highlight just that group and see what it means.

Element details

Atomic number, mass, position in the table, oxidation states, electronegativity and an animated Bohr model of the atom.

What it’s used for

For curriculum elements, where students meet them in everyday life — and a fun fact for every element.

Search

By symbol, Czech or English name, or atomic number — even without diacritics.

Nothing gets lost

Elements that don’t match the search are only dimmed and the table zooms in on the results, so students always see where they are.

What it means

Every value in the element details comes with a short explanation written for students. A “Czech curriculum only” switch shows just what’s taught at Czech schools.

Czech and English

Switch the app’s language right inside it, without changing your phone’s language. Element details always show the English name too.

For every student

VoiceOver support and a legend with symbols, so students with colour vision deficiency can read it too. Works in portrait and landscape.

Who it’s for

For students and teachers.

For students learning element symbols, names and atomic structure, and for chemistry teachers who want a clear periodic table on iPhone and iPad in class.

Safe for kids

No ads, no data collection.

The app needs no internet connection or account, has no ads or in-app purchases, and collects no personal data.
