LEGO® Boost – Creative Coding for Kids

What is LEGO® Boost?

LEGO® Boost is a free Android application from LEGO System A/S that works with the LEGO® BOOST Creative Toolbox set (17101). The app provides a visual programming environment where kids can learn basic coding concepts while controlling motorized LEGO models.

Main features

• Guided activities – Step‑by‑step challenges introduce coding blocks gradually, helping beginners build confidence.
• Customizable projects – After completing the built‑in models, users can design their own creations on the Creative Canvas and program them with the same block‑based interface.
• Digital building instructions – The app includes electronic building guides for the five official BOOST models, making construction easy to follow.
• Progressive coding blocks – New blocks unlock as users advance, expanding the range of possible actions for their robots.

How it works

The app connects to the LEGO® BOOST hub via Bluetooth. Once paired, children drag and drop visual code blocks to define movements, sensor responses, and sound effects. The program is then sent to the hub, which executes the commands on the physical model.

Practical uses

• Introduce basic programming concepts in a playful, hands‑on way.
• Encourage problem‑solving by experimenting with different sensor inputs and motor actions.
• Support STEM learning at home or in classroom settings.

Installation information

Search for LEGO® Boost in the Google Play Store, then tap Install. The app is free to download and does not require a purchase within the app.

Things to know before installing

• The app requires a Bluetooth‑capable Android device.
• While the app itself is free, it is designed to be used with the LEGO® BOOST Creative Toolbox set, which must be purchased separately.
• Internet access is needed for the initial download and for occasional updates.

Who may find it useful?

Parents, educators, and children aged roughly 6‑12 who are interested in building, robotics, or learning to code will benefit from LEGO® Boost. The visual programming approach makes it accessible even for those with no prior coding experience.

Frequently asked questions

Do I need the LEGO® BOOST set to use the app?

The app can be opened without the set, but its core activities and coding challenges are designed around the motorized hub and sensors that come with the set.

Is the app compatible with all Android phones?

Compatibility depends on Bluetooth support and the Android version required by the app. The Play Store listing provides the minimum version needed.

Can I create my own code without following the preset activities?

Yes. After completing the guided challenges, the Creative Canvas lets users build and program custom models using the same block interface.
