The 3D labs

Eight animated labs show bonds and reactions step by step.

Play, pause and drag the timeline to any moment.
Rotate the molecules with one finger. The caption explains each step.

Language, theme and tours

Open Settings to switch between Spanish, English and French, choose light, dark or the system theme, and replay the intro or the guided tour. Settings also shows the installed version, the licenses and the privacy policy.
