Tricky navigation, but super cool to match to actual sky.

The parents' guide to what's in this app.

Educational Value

Kids can learn about the placement of planets and constellations in the sky as they match up the app's virtual sky to their own real-life position and use the app to identify where stars and planets are. The constellation drawings will help kids visualize how random stars are grouped together into fantastical beings. They'll also learn a few fun facts about roughly 30 planets and constellations. Most of all, Ready Jet Go! Space Explorer gives kids a starting point for exploring their night sky and a launching pad for asking many more questions.

Ease of Play

Navigation can be a bit awkward and isn't particularly intuitive: It may take a little while for kids to orient and discover the different ways to interact with the content.

Violence & Scariness
Sexy Stuff

A small icon on the home page takes kids to a listing of other available apps from the same developer; a parent gate protects purchases and downloads.

What parents need to know

Parents need to know that Ready Jet Go! Space Explorer is based on the TV show and recreates the night sky, complete with planets and constellations, for kids to explore. Kids can swipe and tap to learn more or move the device itself around to scan through the sky. Upon opening the app, users will be asked to give permission for the app to access your location data. The app will work even if you decide not to grant access, but the stars in the virtual sky won't match up with where they are in the real sky. Read the developer's privacy policy for details on how and under what circumstances this and other information is collected and shared.

What's it about?

Jet and his friends are here to help kids explore and learn about planets and constellations in READY JET GO! SPACE EXPLORER. Kids can play in two ways: Swipe or move the device to scan through a generic sky, or turn on location services and tap the compass icon to have the app match the sky exactly as kids see it from where they are. Tap on constellations and planets to learn a few fun facts about them, color the constellations with some simple drawing tools, or play hide-and-seek with Jet using clues to figure out where he's hiding.

Is it any good?

This is a solid, though somewhat superficial, introduction to the wonders of the night sky. Exploring the sky and seeing how stars form pictures will certainly be fascinating to lots of kids, although they can learn only three simple facts about roughly 30 planets and major constellations. As kids look for Jet in the hide-and-seek game, there's a bit more substance in the form of carefully worded clues and the guiding hand of Jet's sidekick, Sunspot. In-app navigation controls could use a bit of clarity or explanation, as it's not immediately clear how to use the different features. But by far the most interesting part of this app is that kids can calibrate the virtual sky to their real-world sky and try to match stars and find constellations. Even with the sometimes confusing user experience and information coverage that just barely touches the surface, this feature -- and the fact that the app is free -- makes it worth checking out.

Talk to your kids about ...

  • Families can talk about what they see in the sky from their own backyards. Bring the device out on a clear night and match it up to your sky. Point out the stars you can find, and draw imaginary lines to form the constellations.

  • Help kids research to find out more about the things that most interest them in the sky. Go to the library or bookstore or look online for more information about planets, stars, constellations, and more.

  • Look at the Ready Jet Go! series and online materials to discover more about outer space.
