Blast into Space by Tinybop, an interactive world where kids can play their way to interplanetary knowledge and explore the solar system from their own personal spaceship.

What we love: Cruising over planets for a closer view of their surface and chucking meteorites to test their gravity. Touring Jupiter’s big red spot, Venus’ volcanoes, and Neptune’s diamond sea is pretty stellar too.

Quick tip: If you extend the space-measuring tool way, way, way out, you’ll find the Voyager 1 (which is 14 billion miles from Earth) and unlock a cool Easter egg.

Meet the creator: Several members of the Tinybop team who built the Space app are lifelong space nerds, and everyone learned a lot in the process, says CEO Raul Gutierrez. “For example, who knew that Uranus is thought to have seas of liquid diamond underneath its clouds?”
