Sensor Logger is the easiest way to stream sensor data from your iOS device straight to a locally hosted server in the form of socket.io or HTTP requests. With a stripped down, minimal interface, Sensor Logger provides exactly what you need and nothing that you don't. - Track your device's accelerometer, gyroscope, and magnetometer. - Adjustable streaming period with a maximum speed of roughly 3 polls/second. - Two protocols to use, HTTP or socket.io (WebSocket library) - Sample node.js server with JSON and CSV exporting is available from the developer's website, www.joecrozier.ca/sensor-logger Please note - this app is meant for developers who wish to use their iOS device to monitor the world around them. If you're not comfortable writing code it's recommended you use a different application for this task.
