No. It runs in any web browser, it is free, and there is no signup or account.
Does it work on a tablet?
Yes. Every section is built for tapping and scrolling.
For parents and teachers
The star-size and planet-weight sections tend to land hardest, because both turn an abstract number into something a child can see directly. They support the NGSS 5-ESS1 ideas about the Sun's brightness compared with other stars and the scale of the solar system.
