AP Sensor app for iPhone and iPad

Flip the laboratory and do Physics experiments using your smartphone! Perform your own scientific investigations anytime, anywhere. It records and shows real-time measurements from standard sensors in your smartphone including the accelerometer, magnetometer, gyroscope in the intuitive gauge mode or in a more scientific chart mode. Using the built-in microphone and speaker, it turns your smartphone into a sound level meter, a sound generator and even a sound spectrum analyzer. You may save and share the sensor data for further analysis.
