The app utilizes Rightware's leading Kanzi framework for smooth rendering with HW accelerated 3D graphics. There are two different themes to choose from: traditional style "Adventure" and modern "Marine".
As a bonus, Marine mode contains a damped string suspension with modeled physics for rough conditions. No matter how you move the device, the compass ball just seems to be magically floating in the air.

- The algorithm requires all three movement sensors. Some fairly modern devices in the market do not include gyroscope (for example, Samsung Galaxy Tab 2 10.1).
- Marine mode ball compass is supposed to be viewed from side, not from top. Directions seem opposite if viewed from top.

Gyroscopes are relatively new on Android devices and are usually only equipped on device manufacturers "flagship" phones/tablets. So, unless you have recently purchased one of the more high-end devices available, the chances are that your device does *not* have a gyroscope. If you open Gyroscope Explorer and you get a message saying that the gyroscope does not exist on your device, your device is either not equipped with a gyroscope, the device has been rooted or the manufacturer never implemented the gyroscope in the Android API.
If you do have a gyroscope, be aware that the quality of the drift compensations on the gyroscope sensor vary considerably among devices. In the case that your device has a gyroscope that doesn't work well, there are multiple option to fuse the gyroscope with the acceleration and magnetic sensors. These option, which uses a fusion of the acceleration, magnetic and gyroscope sensors via complementary filter or Kalman filter to determine the rotation of the device, is far more reliable that the gyroscope sensor alone.
You can now log the output from the gyroscope and filters to an external .CSV file.
Gyroscopes measure the rotation of a device with a pair of vibrating arms that take advantage of what is known as the Coriolis effect, which is caused by the Earth's rotation. By measuring changes in the direction of the vibrating arms caused by a rotation and the Coriolis effect, an estimation of the rotation can be produced. The gyroscope is one of three sensors that are always hardware based (the other two are the magnetic and the acceleration sensors) on Android devices. In conjunction with the acceleration sensor, the gyroscope can be used to create other sensors like gravity, linear acceleration or rotation sensors.
If your device is equipped with Android 4.4 or higher, you *might* have the uncalibrated version of the gyroscope so you can see how drift affects the gyroscope sensor relative to the calibrated gyroscope.
Gyro Plane is simply the most efficient way to keep track of your gyro plane flights. With the ability to insert a log entry it will then allow you to view each log entry individually using a convenient drop down selector. After you have entered a log entry, exercise full control by editing or deleting any entry. Frequent flier? View all your log entries at once with the added ability to scroll each entry horizontally to view all your fields, and as if that’s not enough search through all your log entries to quickly find any entry.
The gyroscope rotational speed around the z-axis is visualized as a gray circle.
Compass is red/white.
Accelerometer is green.

This gyro compass does not use the GPS and you can use it offline and without a GPS signal. It uses the magnetic field to determine north.
You can also see where magnetic north is and find out where the other geographical points are relative to it.
The gyro compass is used for navigation and for getting your bearings. Gyro compass is a free app.
Point the phone up to the sky and all the letters come falling down towards you. Touch a letter to hear the sound and drag it to move it around the scene.
Drag the letters around to make and spell your own words to hear each of the letters in the word.
This will keep your kids entertained for hours and reinforce the letters and their sounds.
More function to be added weekly with free updates. Put in your requests in the commments.
This is still in testing so feel free to give me your suggestions and feedback.
Touch screen controls:
__Top Left - Accelerate
__Middle Left - Rotate Left
__ Bottom Left - Brake
__Middle and Drag - Move Spaceship
____(This will change to be controlled by moving your phone around)
__Top Right - Missile (With missile cam)
__Middle Right - Rotate Right
__Bottom Right - Lasers
1. Sit on the floor
2. Hold the phone with your arms straight towards the sky
3. Now twist right, left, up, down, all around to zap those meteors before they hit the ground.
Note: You may need to orient yourself towards north for the over head camera to line up better with your movements.
Good luck ! Leave suggestions along with your comments along with any requests for different games that could use the gyro function like this.
