Sensor Logger

Sensor Logger is an easy-to-use, beautifully designed data logger that logs readings from common sensors on your phone — including accelerometer, gyroscope, GPS, audio, camera and bluetooth devices. An intuitive interface allows you to select your desired sensors. A simple tap of a button initiates the recording function, which works even when the app is in the background. You can view and manage recordings within the app via interactive plots. The export functionality conveniently outputs your recordings in a variety of formats, including Zipped CSV, JSON, Excel and Kml. For advanced use cases, you may also stream data via HTTP during a recording session, or create Studies to collect recordings from other Sensor Logger users systematically with ease.
