An amazing visual gyroscope for your iPhone, iPod or iPad. This application displays a 3d gyroscope that acts just like a real gyroscope would and looks so real you'll want to touch it! And it acts as an educational tool too — press a button and learn about the maths and the history behind gyroscopes.

Gyroscope is an advert supported application.

NOTE: we've received reports that gyroscope-based applications fail to download or install on some iPad 2s running iOS 4.3 prior to 4.3.1. If you have problems downloading this app then please try attaching your device to iTunes and updating it to the newest version of iOS.

What's New in Version 1.2

Gyroscope is now iPad 2 compatible.

Customer Reviews

Nicely done; missing precession.

Very nicely done. One behavior is missing, though: a gyroscope precesses. Being a pilot, I'd really like to see this simulated (perhaps with an option to disable it - but with a brief description as to why precession is there in the first place). It would be fun to tilt the iPad forward and see the axis tilt to the side (in addition to the pitch change.

The description uses an aircraft for illustrating roll, pitch, and yaw. When any of these changes, the precession caused by the rotating propeller must be compensated for, though most maneuvers are slow enough that the effect can be relatively small. That said, on takeoff, rotating to climb attitude will cause noticeable yaw - especially for a tail-dragger. Speaking of which: aerobatic maneuvers result in rapid changes to the plane of the prop's rotation, requiring control input to compensate (most aerobatic planes are tail-draggers).


Different themes would be nice!

The reviews make it seem like the ads are ALL IN YOUR FACE, at least thats the impression I got. In fact they're not that bad IMO... Just the regular iAd at the bottom of the screen.

Not a real gyro

I tested this while driving in a car. This app simply uses your accelerometers.

You can also test this by setting it flat on a table and rotating it. The accelerometers won't detect a change but the gyroscopes will. You will see that, because this is using the accelerometers and not the gyros, it will not detect the rotation.

When going around a corner, a gyroscope will stay vertical. This "gyroscope" does not.
