The official Sphero app for Windows Phone is now in the Windows Phone Store.
The app lets users remote control the small ball-shaped toy via Bluetooth, control speed, colors, core reactor, and boost times and also complete missions, purchase tricks, and master your skills.
Unlike other 3rd party apps the official app will also let you upgrade your firmware.
If you do not already have a Sphero, the second generation of the robotic toy can be had for only $99.95 on Amazon.com.
