This is the sensor data collection app for people who are serious about their data collection. Used widely across both commercial and academic labs. Easy to use, accurate, and captures data from all of the IOS sensors.

▲ The latest app within the Wavefront Labs Data Collection series. The often requested, long-awaited app that collects and integrates all sensors, including the i3D Gyro data.

▲ Collects data from all the sensors including the 3D Gyro
▲ Integrates the 3D Accelerometer data with the 3D gyro data to provide accurate attitude, rotation, and user acceleration data.
▲ Collects data from the GPS including location, altitude, speed, and course.
▲ Collects data from the proximity sensor

Data collected includes:
▲ 3D Accelerometer: X, Y, Z acceleration

▲ 3D Magnetometer and Compass
▲▲ Magnetic and true heading
▲▲ 3D magnetic fields (microTeslas)

▲ Integrated Accelerometer and Gyro data
▲▲ Attitude: pitch, roll, yaw
▲▲ Attitude: Quaternion
▲▲ Attitude: 3x3 rotation matrix
▲▲ Gravitational acceleration X, Y, Z vector
▲▲ User acceleration X, Y, Z vector
▲▲ Rotation rate

▲ Location and GPS
▲▲ Latitude / longitude
▲▲ Course / speed
▲▲ Altitude

▲ Proximity Sensor

** Two collection Modes **

▲ Capture Mode - Captures data to files stored within the device Flash filesystem.
▲ Streaming Mode - Real-time sensor data streamed to another computer with UDP packets.

▲▲ Other Features

▲ Supports data file transfer through iTunes File Sharing
▲ Internal web server allowing you to easily view and transfer collected sensor data files to another computer.
▲ Library manager within the app to allow you to easily view and manage captured sensor data within the app.
▲ Configurable sample rates from 1 to 100 Hertz.
▲ Configurable number of samples
▲ Data captured and transferred as CSV (comma separated) values for easy integration into spreadsheets and other data analysis software.

Note: Some devices don't have all sensors.

Note: Continued use of GPS running in the background can dramatically decrease battery life.

What's New

Version 1.26

Resolved a problem with requesting permission to use the GPS data in some cases that was causing no GPS data to be collected in the app for some people.

Ratings and Reviews

Frustrating to work with


Biggest complaint is that it is so hard to use.

For example, the app resets your IP address and port number EVERY time the app closes. Sensor data can only be streamed when the app is open and the screen is on.

I was able to get it working, contrary to other recent reviews

No work

Bugs hunter

You are 100% failure again. I thought you were joking.

streaming doesn’t work!


app crashes when i turn the streaming on.
